Check for loss of AC power at the 240 VAC outlet. Confirm GFCI (Ground Fault Circuit
Interrupter) has not tripped. Check with a meter or 240 VAC test light that AC power is present
at the end or in your extension cord. Reset AC power if it was not present. Confirm all charger
cables are installed with the correct polarity connections at each battery and that all connec-
tions are clean and tight. Wait for 2 minutes until the unit completes analyzing stage.
System Check OK LED (green) is OFF and Troubleshoot LED (bank1, bank2 or
bank3) is ON (red).
Identify the battery bank LED that is lit, remove AC power and check the battery bank indicated,
for example bank 1, bank 2 or bank 3 (model specific). The LED indicates there is a fault
present. Below are listed typical faults and instructions on how the fault status can be solved:
Note: After making any corrections, reapply AC power.
Poor battery connections - Make sure all connections are tight and clean.
Blown DC cable fuse - Use the ohm meter or continuity tester to make sure all
fuses are healthy and visually inspect the DC battery cables to ensure they have
not been compromised or shorted in any manner.
Reverse polarity - Make sure all wiring connections are color coded and connected properly
and that each bank cable goes to one 12V battery where (+) = red and (-) = black.
Battery too low to charge - Using a digital voltmeter, make sure the battery is over 2.5 volts
DC. If not, have your battery charged out of the boat and have it load tested by your local
battery dealer to ensure it is safe to charge and that the battery is capable of holding a charge.
High battery voltage input - Make sure a bank lead has not been spread across 2 batteries
connected in series for 24 volts DC. If so, correct by following the wiring diagrams on pages 13-20.
Battery(s) not charging, AC Power LED (blue), Charge Mode LED (red)
and Battery Monitor LEDs are ON
Confirm all charger cables are installed with the correct polarity connections at each
battery, and that all connections are clean and tight. Confirm that there are no bank
Battery Trouble Status LED indicators on. With the charger on, read DC voltage at each
battery. If any of the readings are less than 12.8 volts DC, proceed with the following:
A.Disconnect AC power at the 240 VAC outlet.
B.Refer to pages 13-20 in this manual and confirm your charger is connected
correctlyto the battery based on the wiring diagram in Installation section.
C. After completing step B, plug your charger into AC power and observe the LED display. Charger
should be in the charging mode (charging LED under Charge Mode is red). In case the batteries were
completely depleted, after completing a full charging cycle that may take up to 10~12 hours or more,
maintaining LED (green) under Charge Mode and 5 Charge Monitor LEDs (green) are also illuminated.
Note: If a Digital Volt Meter (DVM) is available to you, instead of waiting to complete a full charging
cycle, you can simply use a DVM and take DC voltage measurements across each 12 volts battery.As
long as the voltage continues to increase while the fast charging LED (red) under Charge Mode is on,
this will serve as a confirmation that the charger is properly connected and is properly charging.

Instructions on Wiring your Charger
The wiring diagrams slightly vary depending on how many banks the charger
model supports. To find the correct wiring diagram that matches with your battery
charger model, choose the illustration that has the same number of charger
output bank cables as your battery charger in hand and wire exactly as shown
(choose the illustration that matches your application) for proper charger opera-
tion.
Incorrect wiring can result in reverse polarity. In the event this happens, the
charger has been designed to not fail as a result, however it will cause the
charger to "internally disconnect" and provide "no output" until the (reverse
polarity) caused by putting the "Red" + lead on a - negative battery terminal). In
the event of miswired battery(s), the charger will illuminate a red Battery Trouble
Status LED for the specific battery requiring attention.
Note: Battery Chargers are designed for any combination of group 24, 27, 29, 30 and 31 batteries.
Each battery charger DC output cable must be connected to one (1) 12 volts DC battery (even if
batteries are configured for 24 volts DC or 36 Volt DC trolling motor or system applications). Most
specifically you do not have to remove series or parallel jumper cables to use your Charger.
Note: Your charger must be connected to the batteries to operate. It will not operate as an individual
2 volts power supply.
Installation
Each charger cable must be
connected to 1 battery, as
illustrated. Observe black wire
to (-) and red wire to (+).
Do this for each battery.
When connecting to an engine start battery only, connect the battery bank cable
that is LABELED: "FOR ENGINE BATTERY USE THIS BANK CABLE ONLY".
If there are more charger outputs than batteries, then sets of leads can be
doubled on the larger battery in your system. Typically these are connected to
the more drained trolling motor battery

Your battery charger is designed to be permanently mounted on-board, and can be
mounted either vertically or horizontally.
Always mount your charger in a compartment area that can be properly ventilated during use.
Do NOT mix battery types on-board. All batteries should be of the same age and in
good operating condition.
Do NOT make any electrical connections to the charger or batteries until th steps
below are completed:
Easy Steps for Installation:
Select a mounting location that allows for free air ventilation with a minimum of
6 inches of clear unobstructed space around and in front of your Battery
Charger. Open all battery and engine compartments and ventilate for at least
15 minutes before starting the installation of the charger. Ensure all battery
cables can reach each of the batteries.
Note: For installations requiring an extension of the DC battery charger
cables,please call or visit your retailer or dealer to purchase a 5 foot or 15 foot
battery charger DC cable extenders.
Do not install charger on carpeted, upholstered, vinyl, or varnished areas.
Make sure to place the charger in an accessible area where all indicators are
clearly visible. Install this unit on a hard surface.
Using the battery charger or the enclosed template, mark the position of each
mounting hole. Ensure the mounting screws will not puncture or protrude into a
live well, a fuel or oil tank or the bottom of the boat.
Using a 1/8" drill bit, drill pilot holes in the (4) marked locations as described in
step Apply a silicon sealer in each of the mounting locations to waterproof the
screw holes.
Position the charger over the mounting holes and secure with a power screw-
driver by installing 4 stainless steel # 10 screws. (mounting screws are not
supplied)
Prepare each battery in advance by cleaning each terminal post with a wire
brush until a shiny surface is obtained.
Run cables free from sharp objects and secure the cables with cable ties. Coil
excess cable, do not cut or shorten the length of the cables, as in-line fuses
1/8" pilot hole with silicon sealer
IMPORTANT NOTICE
Confirm the surface you will be mounting
the charger to is adequate in strength and
thickness to hold the battery charger in
place with the mounting screws you have
selected.
Maintain an obstruction free area of 6
inches around the Battery Charger.

are located 4 inches from the end of each red (positive) cable. In addition,there
are fuses in all but one of the black (negative) leads. These fuses protect
hecharger and output cables in the event of a short or reverse polarity. We
recommend the use of wire ties or cable clamps to provide strain relief for the
cables and to reduce the risk of damage to the cables or connections.
Connect the DC output cables as illustrated on pages 16-23. Make sure the
(black) wires are connected to the negative side of the battery and the red
wires are connected to the positive side of the battery
Make sure all DC connections are correct, tight, and free from corrosion.
Locate the AC power cord in an open-air area of your boat at least 21 inches
from the charger, batteries, and fuel fill lines.
Connect a heavy duty UL approved extension cord to your charger first. After
connecting the extension cord to the charger, proceed to plug the extension
cord to a nearby 240VAC GFCI protected (Ground Fault Circuit Interrupt)
outlet. Always remove the extension cord from the 240 VAC outlet first when
charging is completed, followed by unplugging the charger. You are now
connected and charging your batteries, and can monitor the progress by
viewing the LEDstatus indicators.
Important Note: Your battery charger will not operate properly if it is not connected properly
to each battery. Reminder, each DC jacketed bank cable must be properly connected to
individual12V batteries. Number of the DC jacketed bank cables equals the number of
batteries that must be individually connected. For example, a 3 bank battery charger must
be connected to 3 individual 12V batteries, as Illustrated on pages 16-23. For charger
setup, simply choose the illustration that has the same number of charger output bank
cables as your battery charger in hand and wire exactly as shown (choose the illustration
that matches your application) for proper charger operation.
