Safety Considerations
1. Always disconnect your battery
banks and ensure that switches
are “OFF” prior to installing your
regulator.
2. Remove loose-tting clothing or
jewelry, which could become en-
tangled in your motor or other ma-
chinery prior to installing regulator.
3. Wear ANSI-approved safety eye-
wear and protective gear.
4. DO NOT attempt to modify the reg-
ulator. Modications could result in
damage to your charging system,
and will void your warranty.
5. Do not attempt installation if you
are tired or fatigued.
6. Ensure that the engine has cooled
before initiating installation.
7. Do not attempt regulator installa-
tion while using alcohol or medi-
cation that could impair your judg-
ment or reaction time.
8. Always use the right tool for the
job. Improper tool use may dam-
age regulator or your vessel, and
could result in personal injury.
9. Take time to read the manual.
Equipment damage and possible
injuries may result from an incom-
plete understanding of the installa-
tion and operation of the MC-614
regulator. If you are unfamiliar with
marine electrical systems, consult
with a licensed marine electrician.

tors, the MC-614 features user selectable programs for the fol-
lowing battery types: Deep cycle ooded, standard ooded, gel,
AGM and spiral wound AGM batteries. In addition, the regulator
features a universal default program that’s safe for most battery
types, as well as a program that’s designed for use in vessels
utilizing voltage sensitive halogen equipment.
In addition to the user selectable preset programs, the MC-614
features a wealth of advanced programming modes which make
it possible to tailor charging to a wide variety of environments.
When used in conjunction with optional MC-TS-A and MC-TS-B
alternator and battery temperature sensors, the MC-614 features
the ability to monitor and respond to a range of ambient tempera-
ture conditions, including reduction or discontinuation of charg-
ing voltages, should a catastrophic over-temperature condition
occur at the alternator or the batteries.

NOTES:
SUP-0201 | REV A

CAUTION: The following instructions are intended for use by experienced marine
electrical installers. If you are not experienced at installing electrical system
components, we recommend the use of a qualied marine electrical technician.
Regulator Installation
The following information is intended to provide the installer with the
basic information required to complete installation. This section of the
installation manual will deal with mounting, wiring connections and ba-
sic programming for battery type. Additional information regarding ad-
vanced programming adjustments and troubleshooting are addressed
later in the manual.
Unpacking The Box
Your Max Charge MC-614-H regulator kit is packaged with the
following items:
• Max Charge MC-614 regulator
• 54” wiring harness
• Fused (1A) battery sense wire pigtail
• Magnetic programming tool
• Installation and operation manual
If any of the listed items is not included with your regulator kit, call our
customer service department at 360-435-6100. Please note -- if your regulator box is marked Max Charge MC-614, with-
out the “H” designation, your kit will not include the wiring harness or fused battery sense pigtail.
Locate And Mount The Regulator
Choosing a mounting location for your voltage regulator should be deter-
mined based on the following factors; distance from alternator, distance from
inverters, transmitters and other sources of RF noise, convenient access
and readability of the display. The regulator wiring harness is 54 inches long,
providing a three to four foot radius for mounting. Ample airow is essential
for the regulator’s proper operation. Ensure that the regulator is free from
obstructions that restrict air movement around or below the regulator’s alu-
minum heat sink. While the regulator is designed to operate safely in condi-
tions typical of a marine engine compartment, the regulator may be better
protected, and easier to use and monitor if mounted outside of the engine
compartment.
Should it be necessary to install the regulator further than 54 inches from
the alternator, ensure that any wire extensions are properly connected, as
resistance in the harness wiring can affect charging efciency. If harness
length must reach beyond approximately eight feet, replace the RED power
and BLUE eld wires with larger gauge wire that’s sized to ensure voltage
drop < 3%.
Basic Wiring Installation
The regulator’s wiring harness includes six wires required for standard
installation. Four of those wires are connected to the regulator via a
Ford-style plug connector that’s pre-installed on the regulator. These
wires include the Ground (BLACK), Power (RED), Ignition (BROWN)
and Field (BLUE). Plug is shown at right.
In addition, the harness includes a separate Stator (WHITE) wire. The
proper terminal connection points for this, and additional wiring connec-
tions, are illustrated on the pin location legend shown and discussed on
the following pages.

If there is little or no magnetic pull at the pulley shaft or at the rear bearing, initiate the following test:
With the key off and the engine off, remove the large harness plug from the regulator.
Insert the end of a short length of electrical wire to the RED connector slot of
the regulator harness and the other end of the wire to the BLUE connector slot.
This bypasses the regulator and tests the alternator and the harness.
Using your steel screwdriver, inspect for a magnetic eld as described above.
With your voltmeter, check for voltage on the blue wire at the alternator. If volt-
age does not exist, the harness may be at fault. If voltage does exist at the
harness, but no magnetism is present, the alternator is likely to be malfunction-
ing.
If a magnetic eld is present. Both harness and alternator brushes and rotor
appear to be working properly. If no magnetic eld is present, proceed with the
next test.
Testing the actual output of the alternator is known as “Full Field Testing”. This can
be accomplished by jumping a positive 12VDC current to the eld terminal at the
rear of the alternator. This test eliminates both the regulator and the harness, mak-
ing it easier to isolate your investigation to the alternator.
CAUTION: Ensure that all voltage sensitive equipment is turned off prior to starting the engine. Voltage is unregulated
during this test and could damage sensitive electronics. DO NOT let the engine run any longer than necessary to detect
charging. If the system is not charging, remove the alternator and have it inspected by a qualied alternator shop, or call
Balmar for warranty evaluation.
To test the alternator:
Clip a jumper wire to the positive post of the alternator, or on the battery side of the isolator (if an isolator is in use).
Use a SHIELDED alligator clip for post attachment. Unintentional contact between the alligator clip and the alternator
case could result in damage to your electrical system.
Disconnect the eld wire from the rear of the alternator and attach the other end of the jumper wire to the alternator’s
Field terminal (F). CAUTION: Do not allow the wire to contact the case while it is attached to the positive post. The
case is grounded and severe damage could occur.
The regulator is now bypassed. When the ignition is engaged and the motor is started, the voltage should rise and
charging current should be present.
The motor should be run long enough to determine that charging voltage is present. Unregulated voltage can rise
quickly. Do not allow extended unregulated charging to occur without carefully monitoring voltage levels. If the alterna-
tor fails to generate voltage during eld testing, a malfunction of the alternator is likely. Contact your local alternator
repair shop or Balmar’s technical service staff for recommendations.
Conclusion
If your readings differ substantially from the “Expected Readings” listed in the troubleshooting charts, the regulator may
be malfunctioning, or there may be a continuity problem. Contact our technical support staff at [phone]. If you
determine that repair service is necessary for either your alternator or regulator, please gather the following information
before contacting our service technicians: Make and model of alternator. Model of voltage regulator and date of mfg. (date
punched on rear side label of regulator). Voltage readings on red, brown and blue wire at regulator with engine off, key on.
Voltage readings on red, brown and blue wire at regulator with engine running at a fast ideal 1400 rpm.

Voltage Regulator Testing
Set your voltmeter to 12VDC and connect the negative lead to the BLACK ground wire at the regulator as shown at in the
diagram at right.
With the ignition turned OFF, check voltage on the RED (power), Voltage Sense (Terminal #9), BLUE (eld) and
BROWN (ignition) wires in the regulator plug.
Voltages should be as follow:
• RED wire equal to battery voltage
• Terminal #9 RED wire equal to battery voltage
• BLUE wire zero volts
• BROWN wire zero volts
With the ignition in the ON position (engine not run-
ning), check voltage on the RED (power), Secondary
RED on Terminal #13 (voltage sense) BLUE (eld) and
BROWN (ignition) wires in the regulator plug:
• RED wire equal to battery voltage
• Terminal #9 RED wire equal to battery voltage
• BLUE wire between 4V and 11V
• BROWN wire equal to battery voltage
PLEASE NOTE: In systems where the ignition (BROWN) wire is supplied power via an oil pressure switch, jump directly
from test #1 to test #3.
With the ignition in the ON position (with engine running at 1,400 rpm fast idle), check voltage on the RED (power),
Secondary RED on Terminal #9 (voltage sense) BLUE (eld) and BROWN (ignition) wires in the regulator plug. Volt-
ages should be as follow:
• RED wire equal to battery voltage
• Terminal #9 RED wire equal to battery voltage
• BLUE wire between 4V and 11V
• BROWN wire equal to battery voltage
If voltage is not present on the RED, the BROWN and the Positive Battery Sense Wire, the regulator will not work. If volt-
age is as expected at the RED the BROWN and Positive Battery Sense wire, and there is zero, or an unexpected voltage
reading at the BLUE wire, contact our technical support staff at [phone], or e-mail us at [e-mail].
If all voltages at the regulator meet expectations, yet the alternator is not producing charging current, test the alternator.
The following tests are recommended for determining alternator functionality.
Alternator Testing
TEST #1- The following test is used to isolate the alternator and determine if the failure is a result of the alternator. Once
again, testing at either the alternator or regulator is only effective if the wiring, fusing and batteries have been determined
to be in correct working order. The alternator and regulator can be tested for function by determining if a magnetic eld
exists at the alternator’s pulley shaft or rear bearing. To test:
With the ignition in the OFF position, place the tip of a non-magnetic steel screwdriver near the nut on the pulley shaft
or near the rear bearing of the alternator. There should be no evidence of a magnetic eld pulling the screwdriver to-
ward the alternator. (A slight amount of magnetism may be present, due to residual voltage in the alternator.)
Engage the ignition, without starting the engine, to activate the voltage regulator. If an oil pressure switch is used, a
jumper between the RED and BROWN wires in the Ford-style plug will activate the regulator.
After allowing time for the regulator’s start-up delay, place the head of a steel screwdriver near the nut on the pul-
leyshaft or near the rear bearing of the alternator. There should be substantial magnetic pull. If a magnetic eld is
present, the voltage regulator, alternator brushes and rotor are likely to be working properly.

Additional Regulator Features
Small Engine Mode
In situations where additional power is needed for propulsion, the MC-614 provides the option to manually reduce regula-
tor eld output by approximately one half. This option, called Small Engine Mode, can be accessed by creating a direct
pathway between the positive and negative Alternator #1 Temperature Sensor terminals.
This can be done by splicing into the positive and negative wires of the Alternator Tem-
perature Sensor cable (MC-TS-A) with a switched wire. With the switch in the OFF posi-
tion, the Alternator #1 Temperature Sensor will work normally. With the switch in the ON
position, the regulator will reduce eld output by approximately 50%.
To enable the Small Engine Mode:
1. If the Alternator Temperature Sensor cable is being used, replace the female termi-
nal connectors on the cable with Multi-Stack Connectors (Ancor Part # 230612).
2. Install a standard ON/OFF switch in a location that’s easily reached from the helm.
3. Run wires from the switch back to the positive and negative terminals of the Alterna-
tor #1 Temperature Sensor terminals (terminals #5 and #6).
4. Add appropriate connectors to the switched wires and connect to the positive and
negative terminal connections.
Dash Lamp
The MC-614 provides a Dash Lamp circuit that’s capable of providing a signal to a user supplied and installed audible or
visual alert if the following issues were to occur while the regulator is in operation;
• Low Battery Voltage <12.8V
• High Battery Voltage >15.5V
• High Alternator Temperature >225˚F (Requires installation of MC-TS-A sensor cable.) Temperature adjustable.
• High Battery Temperature >125˚F (Requires installation of MC-TS-B sensor cable.)
• Alternator Failure (No voltage on stator).
Aux #1 Lamp
The MC-614 provides an Auxiliary Lamp circuit that’s capable of providing a signal to a user supplied and installed audible
or visual alert to indicate the following while the regulator is in operation:
• Small Engine Mode is activated,
• Regulator is at full eld.
System Troubleshooting
Regulator Troubleshooting
The majority of charging difculties can be attributed to damage, corrosion or wear at wiring, fusing or wiring connec-
tions. Before attempting to troubleshoot alternator or regulator issues, be sure to address the following:
1. Remove and clean all charging system electrical connections (positive and negative). Check the voltage regula-
tor’s harness for continuity. Wires and terminals can and will become corroded, and need to be cleaned or replaced.
Ensure that the regulator’s ground wires are provided with a clean connection to system ground.
2. Inspect and replace 10A and 1A ATC type fuses in the regulator wiring harness if fuses appear to be damaged or
corroded. Ensure that the fuse holder is also free of corrosion.
3. Charge all batteries to their proper fully charged state, and determine if they are serviceable. If your batteries are
ooded-type, use your hydrometer to determine their condition.
4. Check and tighten alternator belt. If the belt show signs of wear or damage, replace it. Always replace existing belts
with the nest quality replacements available.
If batteries and wiring are in suitable condition, use the tests on the following page to determine if charging problems are
a result of a faulty alternator or regulator. These tests provide an opportunity to isolate the alternator, regulator and wir-
ing harness in order to determine the problem source. In order to perform these tests, you will need an independent DC
meter (preferably a digital type). In an emergency, a 12V light bulb or test light can be used to help determine if power or
working grounds exist. An amp meter and a battery hydrometer with a thermometer are also helpful diagnostic tools.

Installation By Wire
Install BLACK Ground Wire
The BLACK Ground Wire (#1 in diagram at right) are included in the four-wire Ford-style plug on the wiring harnessand
are factory installed on regulator packages designated with “H” at the end of the model number. The other end of the
Ground Wire is tted with a ring terminal connector. In most applications, this
wire can be connected directly to the alternator’s ground terminal post. Both
alternators and regulators must be connected to system ground.
Install RED Power Wire
The RED Power Wire (#2 in diagram at right) is included in the four-wire Ford-
style plug and is factory installed on regulator packages designated with “H” at
the end of the model number. The other end of the Power Wire is tted with a ring
terminal connector. In most applications, this wire can be connected directly to
the alternator’s positive output post. When a diode-type battery isolator is used,
the power and voltage sense (#9) wires must be connected to the battery side
of the battery isolator. Power Wire is equipped with 10-amp ATC type fuse. The
Power Wire must be fused to ensure against damage to the voltage regulator.
Install BROWN Ignition Wire
The BROWN Ignition Wire (#3 in diagram at right) provides the ON/OFF voltage
for the regulator. This wire is included in the Ford-style plug at the regulator end
of the wiring harness. The other end of the wire is tted with a butt connector.
Typically, the ignition wire is connected to the ON side of the ignition switch. This
may be at the actual switch, or to the wire in the existing engine wiring loom that
delivers switched voltage from the ignition switch. In some cases, an oil pres-
sure switch may be used to activate the regulator. In either case, the regulator’s ignition wire must see zero volts when
the engine ignition is switched off.
Install BLUE Field Wire
The BLUE Field Wire (#4 in diagram at right) provides regulated current to control alternator output. The wire is included
in the wiring harness Ford-style plug and is pre-connected at the regulator. At the other end of the wire, you’ll nd either
a plug or a ring terminal, depending on the alternator’s eld terminal connection. Attach the eld wire to the alternator’s
eld terminal.
Install Alternator Temperature Sensor
The optional Alternator Temperature Sensor (MC-TS-A) allows your MC-614 voltage regulator to monitor your alternator
for temperatures in excess of safe operating levels. The MC-TS-A
sensor includes a 54” cable, a sensing attachment lug and positive
and negative regulator plug-in connectors. To install the MC-TS-A:
1. Connect the sensor lug to one of the four bolts that hold the alter-
nator’s front and rear cases together. Extend sensor cable to the
regulator. The cable can be included within the regulator’s wiring
harness, or can be run alongside the harness and attached with
cable ties.
2. Connect the positive and negative female connectors to the Al-
ternator Temp. Sense terminals on the regulator (#5 is negative.
#6 is positive). It is essential that the terminals match the polarity
of the regulator connection pins (red wire to positive terminal and
black wire to negative terminal).
Install Battery #1 Temperature Sensor
The optional Battery Temperature Sensor (MC-TS-B) allows your Max Charge MC-614 voltage regulator to monitor your
battery bank for changes in battery temperature, and adjust charging voltages to suit. The MC-TS-B sensor includes a
20-foot cable, a sensing attachment lug and positive and negative regulator plug-in connectors. To install the MC-TS-B:
1. Connect the sensor lug to the battery negative post closest to the center of the battery bank. Extend sensor cable to
the regulator
2. Connect the positive and negative female connectors to the Battery temperature sensors on the regulator (#7 is nega-
tive. #8 is positive). It is essential that the terminals match the polarity of the regulator connection pins (red wire to
positive terminal and black wire to negative terminal connectors).

Install Positive Battery Sense Wire
(REQUIRED FOR REGULATOR OPERATION)
Included with the MC-614 wiring harness kit is a fused wiring pigtail
which features a ring terminal at one end and a butt connector at the
other. In the center is a 1-Amp ATC-type fuse and fuse holder. This
wire MUST be connected at the (#9) Positive Battery Sense terminal.
A female quick connect plug has been pre-attached on the terminal
#9 pin. To complete installation of the sense circuit:
1. Identify the favored location for battery sensing. In most instances,
the positive output of the alternator, the common side of a battery
switch, or the positive post of the battery being charged will work
best. If the batteries are connected to a battery isolator, the
positive sense wire must be connected to the battery side of the
isolator, preferably at the larger of the battery banks.
2. Attach the included wiring pigtail with 1-amp fuse to a length of wire of sufcient to reach the desired sensing location.
If the length of the wire run between the regulator and the sensing location is 8’ or less, a 16-gauge wire is satisfactory.
If the wire run exceeds 8’, increase the wire size to 14 gauge.
3. Remove the female 1/4” spade terminal from the terminal #9 pin. Crimp the spade terminal to the sense wire and
reconnect the spade to the #9 terminal pin.
Install WHITE Stator-In And Tach-Out Wires
When an electric tachometer is used, the alternator’s stator output will provide the electrical pulse needed to drive the
tachometer. The MC-614 has been designed to provide regulated tach output when the WHITE stator wire is connected
to the regulator’s Stator In (#12 in diagram) terminal and the outfeed wire to the electric tachometer is connected to the
Tach Out terminal (#13 in diagram).
Stator output can also be used to detect alternator failure. See Page 6 for details.
When the tachometer is connected via the MC-614, the regulator will ensure that it will not discontinue supplying eld
current when the batteries are fully charged. When connecting the tachometer to the alternator stator output, it will be
necessary to determine the number of poles in the alternator in order to properly adjust your tachometer. Most Balmar
alternators feature 12-pole rotors and stators, though, in some cases, the pole count may be 14. See alternator manual for
specics. See your tachometer manual for adjustment instructions.
Install Battery #2 Temperature Sensor
Your Max Charge MC-614 voltage regulator can accomodate a secondary battery temperature sensor. Used in conjunction
with an optional MC-TS-B battery temperature sensor, the regulator can monitor temperature at a secondary battery bank
and respond to a battery over-temperature condition by discontinuing charging.
To install a secondary battery temperature sensor:
1. Connect the temperature sensor to the secondary battery bank following the directions provided for the primary battery
temperature sensor.
2. Plug the positive and negative sensor to the appropriate positive connector; the BLACK negative sensor wire should
be connected to terminal pin #14. The RED positive sensor wire should be connected to the #15 terminal pin.
Data TX and Data RX
Data TX and RX circuits provide a connection point with outside monitoring equipment. At this time, the Data TX and RX
circuits are only for factory use.

CAUTION: Reversing the polarity of the terminal connections on any of the alternator or battery
temperature sensors can result in invalid sensing and potential damage to alternators, regulator
and/or batteries.
Alternator Temperature Threshold. Controls the setpoint at which point eld current is reduced
when the the alternator temperature sensor indicates an over-temp condition at the alternator. Requires
temperature sensor installation. Preset at 108˚.
Float Voltage. Controls the target voltage for oat stage. Adjustment spans from 13.0 to 13.8 volts.
Default is based on battery program selected. To reverse direction of scroll, release magnet and wait for
LED to display Fv code. Re-activate switch and release when desired value is indicated.
Float Time. Controls time setting for oat mode. Standard value set is 18 minutes. Settings are from 6
minutes to 12 hours. To reverse direction of scroll, release magnet and wait for LED to display F1c code.

96%. To reverse direction of scroll, release “f” code. Reactivate switch with magnet and release when
desired value is indicated.
Field Threshold - Bulk To Absorption . Controls the criteria used to determine eld output re-
quired to maintain calculated bulk charging mode. Factory set at 65% eld output. Raising “fba” shortens
calculated bulk charge time. Lowering “fba” increases calculated bulk charge time. Span of adjustment
is 16% to 96%. To reverse direction of scroll, release magnet and wait for LED to display “fba” code. Re-

Battery Equalization
Due to the hazardous nature of equalization (the intentional overcharging of batteries to remove sulfation from the battery
plates) we strongly recommend that the process be done at the dock with a voltage-adjustable shorepower charger. If it is
absolutely impossible to do so, equalization can be done with the alternator and regulator by doing the following:
1. In Advanced programming, Pra, change the following values.
2. Cl to a voltage above the desired equalize voltage.
3. AHL to a voltage above the desired equalize voltage.
4. Bv to the desired equalize voltage.
5. Blc to the desired equalize time.
6. Disconnect ALL battery temperature sensors.
7. YOU MUST MONITOR THE BATTERIES DURING EQUALIZE PROCESS!
8. Once the equalization is complete, activate the regulator’s basic programming and reset the battery program mode to UFP, and
allow the program to save. Once saved, access the basic programming mode again and reset for the desired battery program.
WARNING: EQUALIZATION IS A MANUAL PROCESS WITH POTENTIAL DANGERS. DO NOT LEAVE SYSTEM UNATTENDED.

2. Connect the negative terminal on the lamp to the Aux. #1 terminal on
the regulator.
Install Dash Lamp
The Max Charge Dash Lamp (#17) terminal provides the ability to activate a visual or audible indicator when the regula-
tor monitors the following conditions: Low system voltage, high system voltage, high alternator temperature, high battery
temperature (temperature conditions are only indicated when appropriate temperature sensors are connected) and no
voltage on stator, indicating that the alternator has failed. When a described condition is detected, the regulator sends the
Dash Lamp terminal from neutral to ground. To utilize the Dash Lamp function:
1. Connect a small LED or incandescent lamp, or an audible (piezo) alert
2. Connect the negative terminal on the lamp or audible alert to the Dash
Lamp terminal on the regulator.

Magnetic Reed Switch
Looking much like a small thermometer atop the regulator’s circuit board, the magnetic reed switch provides a durable,
sealed interface that enables the user to set basic
and advanced regulator programming features.
Included with the regulator is a small screwdriver
that doubles as the regulator’s programming tool.
A small magnet embedded in the tip of the screw-
driver’s handle allows the user to activate the
magnetic reed switch. By holding the magnet to
the RED dot located at the end of the reed switch, the user allows the user to scroll through the regulator’s various program
modes and individual program selections.
Initial Pre-Flight Test And Start-Up
-
fore turning on the engine, it is advisable to check voltages at the following terminal connections to ensure that the wiring
the regulator turned on.
Note: If the regulator’s BROWN ignition wire is receiving it’s switched source of voltage from an oil pressure switch, it may
be necessary to start the engine before applying test #2. If the engine must be run to accomplish test #2, be sure that
alternator is properly cabled on both positive and negative sides to the battery being charged. Failure to do so could result
in damage to the regulator and alternator.
Using your hand-held multi-meter, test the following wiring terminals for voltage:
TEST #1: Engine/Ignition Off
• Primary RED Power Wire (Terminal #2) >12V
• Positive Voltage Sense Wire (Terminal #9) >12V
• BROWN Ignition Wire (Terminal #3) 0V
• Primary BLUE Field Wire (Terminal #4) 0V
TEST #2: Engine/Ignition ON
• Primary RED Power Wire (Terminal #3) >12V
• Positive Voltage Sense Wire (Terminal #9) >12V
• BROWN Ignition Wire (Terminal #2) >12V
• Primary BLUE Field Wire (Terminal #1) 4-12V

AP.1

Regulator Operation
The MC-614 regulator’s microprocessor controlled charging system uses a sophisticated, multi-stage prole to deliver
maximum charging output, while protecting the batteries from overcharging damage. When the regulator is rst turned on,
the processor performs a quick one-second self diagnostic assessment. Following that diagnostic, the MC-614 initiates a
charge program as follows:
1. Start Delay - Factory set at one second. Can be user-adjusted to a maximum of 999 seconds in the regulator’s ad-
vanced programming mode. See Advanced Programming section for adjustment instructions.
2. Soft Ramp - Gently increases voltage to bulk preset levels based on battery program selected.
3. Bulk Charge - The most aggressive of the charging stages. Voltage is held at a pre-set level, specied by battery
program selected, for a set time period. Factory-set bulk time is 18 minutes. Adjustable in 6-minute increments.
4. Calculated Bulk Charge - Holds voltage at bulk level for six minutes, then calculates battery condition by comparing
existing voltage, time at voltage, and eld percentage to target values. If values are met, the regulator advances to
the next stage. If values are not met, the regulator continues to bulk charge and compares real-time to target values.
This will re-occur until all values are met.
5. Ramps down to Absorption voltage.
6. Absorption Charge - Regulator continues to control the alternator’s output voltage for an additional 18 minutes at
approximately 2/10’s of a volt below bulk charging voltage. Adjustable in 6-minute increments.
7. Calculated Absorption Charge - Holds voltage at absorption level for six minutes, then calculates battery condition
bycomparing existing voltage, time at voltage, and eld percentage to target values. If values are met, the regulator
advances to the next stage. If values are not met, the regulator extends the absorption charge and compares real-
time to target values. This will re-occur until all values are met.
8. Ramp down to Float.
9. Float Charge - Regulator continues to control the alternator’s output voltage for an additional 18 minutes, typically
at a volt less than bulk voltage (based on battery program presets). After that initial xed time period, the regulator
can respond to increased charging demand by cycling to absorption voltage. After 12 hours of continuous operation,
the regulator will automatically revert to absorption voltage through calculated absorption and back to oat charging
stage.

Basic Programming
Programming The Belt Load Manager
The MC-614 provides the ability to manage regulator eld potential, making it possible to govern the horsepower loads
placed on the drive belt(s) by the alternator. The Belt Load Manager can also be used to protect the alternator from extraor-
dinary load created by a battery load that’s too large for the alternator’s capacity. The Belt Load Manager is accessed in
the basic programming mode, directly after the battery type programming mode. The Belt Load Manager can be accessed
at the same time the battery program is set, or by itself. To program the Belt Load Manager
When activating the programming mode, keep in mind that the regulator will scroll through the basic programming mode
three times before saving and returning to the operational mode. To adjust the regulator for your battery type:
1. Turn on the regulator. This may be accomplished by turning the ignition switch at the panel to the ON position. If the
regulator’s BROWN ignition wire is connected to an oil pressure switch, it may be necessary to start the engine to
activate the regulator.
2. If the battery type program has been adjusted, TOUCH / HOLD when entry into the Belt Load Manager is indicated by
the bEL display on the regulator’s LED.
3. If you don’t wish to adjust the battery programming, TOUCH / HOLD the RED dot when the regulator is activated.
RELEASE when the Pro display is indicated. The regulator will indicate bA, for battery type, and will cycle to bEL.
4. TOUCH / HOLD. The regulator display will indicate b-0 (indicating that the Belt Load Manager is off). Continue to
HOLD. The regulator display continue to scroll through seven settings. Each setting decreases the eld potential by
approximately seven percent.
5. RELEASE when the display indicates your desired level of eld reduction. The display will cycle to bEL. You can re-
activate to change your selection, or wait until the regulator cycles to the next programming mode.
6. The display will cycle to Ab2, indicating the selection mode where the user can toggle between a secondary alternator
temperature sensor or a secondary battery temperature sensor on terminals #14 and #15.
Programming For Short Or Long Display Mode
You can choose the amount of information displayed on the regulator. The information displayed on the short or long dis-
play is detailed on Page 8 of the manual. To adjust the regulator for short or long display:
1. TOUCH / HOLD when entry into the short/long display selector is indicated by dSP on the regulator’s LED.
2. The regulator display will indicate codes Sd (for short display) or Ld (for long display).
3. RELEASE when the display indicates your desired display mode. The display will cycle to dSP. You can re-activate to
change your selection, or wait until the regulator cycles to the next programming mode.

Programming For Alternator Failure Advisory Mode (BDL)
The regulator provides a ground signal on the dash lamp terminal when the following conditions occur: low battery volt-
age (<12.7V), high battery voltage (>15.5V), high battery temperature (>52˚C), or high alternator temperature (105˚C). In
addition, the user has the option to send the dash lamp to ground in the event that the stator output drops to zero volts.
The Regulator’s Default bdL setting is ON. Monitoring stator output is an optional function which can be turned on or off
in the basic programming mode. The regulator’s default setting for the bdL mode is ON, meaning that the stator output is
being monitored. This function can be used in conjunction with a relay to control a charge indicator lamp.
To enable or disable the stator monitoring function, activate and hold when the bdL mode is indicated. Release when the
desired setting is shown. NOTE: Stator wire must be connected to the regulator’s Stator-In terminal to use this function.

Regulator Programming Modes
Using The Magnetic Reed Switch
Control of the MC-614 regulator’s basic and advanced programming
modes is provided by a magnetic reed switch located in the upper left corner
of the regulator’s circuit board. The reed switch provides selectable control of
the regulator’s programming without creating an intrusion point as is common on
many other adjustable voltage regulators currently on the market.
A small screwdriver with a magnet embedded in the tip of the handle is included to
activate the magnetic reed switch. While any magnetic tipped tool can be used, the
Balmar programming screwdriver does an excellent job as an interfacing tool.
Programming is accomplished by contacting and removing the magnet from the
RED dot afxed to the regulator’s epoxy potting. If the magnet has difculty ac-
tivating the reed switch at that position, try moving the up and down along the
length of the reed switch until the RED light is illuminated at the top of the LED
display, between the second and third display digits. The RED light indicates acti-
vation of the the reed switch.
Within the basic and advanced programming instructions, activation of the reed
switch will be described by the following actions:
• TOUCH / RELEASE - Indicates the action of contacting and immedi-
ately removing the magnet from the reed switch
• TOUCH / HOLD - Indicates the action of contacting and holding the
magnet to the reed switch
• TOUCH / HOLD / RELEASE - Indicates the action of contacting and holding the magnet to the reed switch,
then releasing the reed switch be removing the magnet from the RED dot on the epoxy potting
Basic Programming
Programming For Battery Type
The MC-614 features selectable programs for the following battery technologies; Standard Flooded (FSb), Deep Cycle
Flooded (FdC), gel (gEL), AGM (AgL), Optima (OPS), as well as a factory default program (UFP) and a program for sys-
tems with voltage sensitive halogen equipment (HAL). Programming can be done whenever the regulator is active. Sys-
tem voltage must be greater than 12.5V for programming changes to be saved.
When activating the programming mode, keep in mind that the regulator will scroll through the basic programming mode
three times before saving and returning to the operational mode. To adjust the regulator for your battery type:
1. Turn on the regulator. This may be accomplished by turning the ignition switch at the panel to the ON position. If the
regulator’s BROWN ignition wire is connected to an oil pressure switch, it may be necessary to start the engine to
activate the regulator.
2. Once the regulator is on and the display is scrolling, TOUCH / HOLD the magnetic end of the programming screw-
driver to the RED dot on the regulator as described above.
3. Continue to hold the magnet to the RED dot. The letters PRO will appear on the LED.
4. Continue to hold the magnet to the RED dot. The letters BA will appear on the LED.
5. Continue to hold the magnet to the RED dot. The LED display will begin to scroll through the various battery codes.
6. When the desired battery code is displayed, RELEASE the magnet from the RED dot.
7. The display will indicate BA once again. At this point, you have the option to re-enter the battery type mode by re-
applying the magnet to the RED dot. Otherwise, the display will cycle to bEL, indicating entry into the Belt Load Man-
ager mode.
