HYFIRE®VIASERIES
ELECTRONIC IGNITION CONTROL
PART NO. 6852M
INSTALLATION INSTRUCTIONS
FORM 1522 (REV. B) 03/01
GENERAL INFORMATION
Battery
The HYFIRE®VIA Series Ignition Control operates on any negative
ground, 12 volt electrical system with a distributor. It will also work
with 16 volt batteries and can withstand a momentary spike of 24 volts
in case of jump starts. This system delivers full voltage with a supply
of 10-18 volts, and operates with a supply voltage as low as 8 volts.
If your application does not use an alternator, allow at least 15 amp/
hour for every half hour of operation. If you crank the engine with the
same battery or other accessories, such as an electric fuel or water
pump, increase the amp/hour rating
Coils
For optimum performance with your HYFIRE®VIA Ignition Control, we
recommend Mallorys PROMASTER®Coil P/N 29440. Mallorys
PROMASTER®Coil P/N 29625 can also be used, as well as most
stock coils or aftermarket coils designed as stock replacements.
NOTE: Do not use Mallorys PROMASTER®Coil P/N 28880.
Tachometers
The yellow wire on the HYFIRE®VIA Ignition Control provides a trig-
ger signal for tachometers, shift lights, or other add-on RPM activated
devices. This wire produces a 12 volts square wave signal with a 20%
duty cycle.
Some vehicles with factory tachometers may require a tach adapter
to work with the HYFIRE®VIA Ignition Control. If your GM vehicle
uses an inline filter, it may cause the tach to drop to zero on accelera-
tion. If this occurs, bypass the filter. For more information on tachom-
eters, see page 4.
Foreign Vehicles
Because of modern fuel injection systems, some foreign vehicles may
require a tachometer/fuel injection adapter to work with the HYFIRE®
VIA Ignition Control.
NOTE: Do not install the HYFIRE®VIA Ignition Control in any
vehicle that is originally equipped with a CD ignition control.
Spark Plugs and Wires
High quality, spiral wound wire and proper routing are essential to the
operation of the HYFIRE®VIA Ignition Control. This type of wire pro-
vides a good path for the spark to follow while minimizing electromag-
netic interference (EMI).
NOTE: Do not use solid core spark plug wires with the HYFIRE®
VIA Ignition Control.
Routing
Wires should be routed away from sharp edges, moving objects, and
heat sources. Wires that are next to each other in the engines firing
order should be separated. For example, in a Chevy V8 with a firing
order of 1-8-4-3-6-5-7-2, the #5 and #7 cylinders are positioned next
to each other on the engine as well as in the firing order. Voltage from
the #5 wire could jump to the #7 wire. This could cause detonation
and engine damage.
For added protection against cross-fire, Mallory offers PRO SHIELD
insulated sleeving. PRO SHIELD is a glass woven, silicone coated
protective sleeve that slides over your plug wires. It also helps reduce
damage from heat and sharp objects.
Spark Plugs
Using the correct spark plug and heat range is important for optimum
performance. Because there are so many variables to consider, we
suggest starting with your engine manufacturers spark plug recom-
mendation. From there, you can experiment with small changes in
plug gap and heat range to obtain the best performance from your
engine. Use the chart at right as a starting point. We also recommend
non-resistor spark plugs.

When you find a suitable location to mount the unit, make sure all
wires of the ignition reach their connections. Hold the ignition in place
and mark the location of the mounting holes. Use a 1/8" drill bit to drill
the holes. Use the supplied self-tapping screws to mount the box.
WIRING
Wire Length
All of the wires of the HYFIRE®VIA Ignition Control may be shortened
as long as quality connectors are used or soldered in place. To lengthen
the wires, use one size larger gauge wire (12 gauge for power leads,
16 gauge for all others). Use the proper connectors to terminate all
wires. All connections must be soldered and sealed.
Grounds
A poor ground connection can cause many frustrating problems. When
a wire is specified to go to ground, connect it to the chassis. Always
connect a ground strap between the engine and chassis. Connect
any ground wires to a clean, paint-free metal surface.
Ballast Resistor
If your vehicle has a ballast resistor in line with the coil wiring, it is not
necessary to bypass it. This is because the HYFIRE®VIAIgnition Con-
trol receives its main power directly from the battery.

MISCELLANEOUS INFORMATION
Sealing
Do not attempt to seal the HYFIRE®VIA Ignition Control. All of the
circuits of a HYFIRE®VIA receive a conformal coating of sealant that
protects the electronics from moisture. Sealing the HYFIRE®VIA will
not allow any moisture that seeps in through the grommets to drain
and may result in corrosion.
Welding
To avoid any damage to the HYFIRE®VIA Ignition Control when weld-
ing on the vehicle, disconnect the positive (red) and negative (black)
power cables of the HYFIRE®VIA Ignition Control. It is also a good
idea to disconnect the tachometer ground wire as well.
Distributor Cap and Rotor
We recommend installing a new distributor cap and rotor when install-
ing the HYFIRE®VIA Ignition Control. Be sure the cap is clean inside
and out, especially the terminals and rotor tip. On vehicles with smaller
caps, it is possible for the air inside the cap to become electrically
charged causing crossfire which can result in misfire. You can prevent
this by drilling a couple of vent holes in the cap. Drill the holes be-
tween terminals at rotor height, facing away from the intake. If needed,
place a small piece of screen over the holes to act as a filter.
HYFIRE®VIA Diagnostic LED
On the end panel of your Hyfire 6A ignition there is a small hole. Be-
hind this hole is a red LED indicator. This serves two purposes: when
you first turn on the ignition switch, the LED will flash rapidly 3 times.
This indicates that the ignition system has power, and that the micro-
processor is running properly. In addition, the LED will flash when
receiving a proper trigger signal from the vehicle. If, after a normal
power-up, the LED doesnt flash when cranking the engine, you should
check your triggering circuit for problems. If the LED flashes when
the engine is cranked, but there is still no spark, the problem
lies somewhere else.
HYFIRE®VIA Cylinder Selection
Your HYFIRE®VIAIgnition comes from the fac-
tory set up for 8 cylinder operation. If you want
to use this ignition with a 4 or 6 cylinder en-
gine, you must first remove the four screws
that hold the endplate with the LED hole. Once
the endplate is removed, youll see the end of
the circuit board. Look for the two-section
switch. To select 4 cylinder mode, move the
switch marked 1 to the ON position. To se-
lect 6 cylinder mode, move the switch marked
2 to the ON position. If both switches are OFF,
or both are ON, the ignition will run in the 8 cylinder
mode. See Figure 1.
MOUNTING
The HYFIRE®VIA Ignition Control can be mounted in any position. If
you mount it in the engine compartment, keep it away from moving
objects and heat sources. Do not mount the unit in a closed area,
such as the glovebox.

WIRE FUNCTIONS
Power Leads
The two heavy gauge wires (14 gauge) that deliver battery voltage to
the ignition:
Heavy Red Connects directly to the battery positive (+) terminal
or to a positive battery junction. It could also be con-
nected to the positive side of the starter solenoid.
NOTE: Never connect this wire to the alternator.
Heavy Black Connects to frame or chassis ground.
Trigger and Coil Leads
Small Red Connects to a switched 12 volt source, such as the
ignition key.
Orange Connects to the positive (+) terminal of the coil.
NOTE: This is the only wire that makes electri-
cal contact with the coil positive (+) terminal.
Small Black Connects to the negative () terminal of the coil
NOTE: This is the only wire that makes electri-
cal contact with the coil positive () terminal.
Trigger Wires Either of two circuits will trigger the HYFIRE®VIA
Ignition Control: a points circuit (white wire) or a mag-
netic pickup circuit (violet and green wires).
NOTE: The two circuits will never be used
together.
White Connects to points, electronic ignition amplifier out-
put or to the green wire of a Mallory timing acces-
sory. When this wire is used, the magnetic pickup
connector is not used.
Violet/Green These wires are routed together in one harness to
form the magnetic pickup connector. The connector
plugs directly into a Mallory distributor or crank trig-
ger. It will also connect to factory magnetic pickups
or other aftermarket pickups. The violet wire is posi-
tive (+) and the green is negative (). When these
wires are used, the white wire is not used. Consult
the chart that shows the polarity of other common
magnetic pickups
Yellow Connects to the tachometer.
ROUTING WIRES
Route all wires away from heat sources, sharp edges, and moving
objects. Route the trigger wires separate from the other wires and
spark plug wires. If possible, route them along a ground plane, such
as the block or firewall, which creates an electrical shield. The mag-
netic pickup wires should be routed separately and twisted together to
help reduce extraneous interference.
WARNING: The HYFIRE®VIA Ignition Control is a capacitive dis-
charge ignition. High voltage is present at the coil primary termi-
nals. Do not touch these terminals or connect test equipment to
them.
PRESTART CHECKLIST
The only wires connected to the coil terminals should be the or-
ange connected to coil positive (+) and black connected to coil
negative ().
The small red wire is connected to a switched 12 volts source,
such as the ignition key.
Power leads are connected directly to the battery positive and nega-
tive terminals.
If youre not using an alternator, the battery should be connected
and fully charged.
The engine is equipped with at least one ground strap to the
chassis.
THEFT DETERRENT
The HYFIRE®VIA Ignition Control provides an easy way to install a
theft deterrent kill switch. See Figure 2.
White Wire Trigger
When using the white wire to trigger the HYFIRE®VIA Ignition Control,
install a switch across the magnetic pickup violet wire to ground. When
the violet wire is grounded, the vehicle will crank but will not start.
Magnetic Pickup Trigger
When using the mag pickup to trigger the HYFIRE®VIA Ignition Control,
install a switch to the white wire and the other side to ground. When the
white wire is grounded, the vehicle will crank but will not start.

TROUBLESHOOTING
This section offers several tests and checks you can perform to en-
sure proper installation and operation of the HYFIRE®VIA Ignition
Control. If you experience a problem with your HYFIRE®VIA, first
check for proper installation and poor connections. You can eliminate
many problems by checking these items. If you have any questions
concerning your HYFIRE®VIA Ignition Control contact the Mallory
Technical Service Department at 775-882-6600, Monday through Fri-
day, 8:00 am to 5:00 pm Pacific time.
Tach/Fuel Adapters
If your tachometer does not operate correctly, you probably need a
Mallory tach adapter. Consult the Tachometer Compatibility List at
right for common tachometers and compatible tach adapters.
No-Run on Foreign Vehicles
Some foreign vehicles with fuel injection systems may require a ta-
chometer/fuel injection adapter to run with the HYFIRE®VIA Ignition
Control. Often, the same trigger source is used to operate an ignition,
tachometer, and fuel injection. This results in a voltage signal that is
too low to trigger the fuel injection. A tach/fuel injection adapter will
usually solve this problem.
Inoperative Tachometers
If your tachometer fails to operate with the HYFIRE®VIA installed, you
may need a Mallory tach adapter. Before purchasing a tach adapter,
try connecting your tachometer trigger wire to the yellow wire of the
HYFIRE®VIA Ignition Control. This output produces a 12 volt, square
wave. If the tach still does not operate, you will need a tach adapter.
Two different tach adapters are available:
PN 29078 If you are using the magnetic pickup connector (green
and violet wires) to trigger the HYFIRE®VIA, you will
need this adapter.
PN 29074 If your tach was triggered from the coil negative termi-
nal (voltage trigger) and you are suing the white wire
to trigger the HYFIRE®VIA, you will need this adapter.
Ballast Resistor
If you have a current trigger tach (originally connected to coil (+) posi-
tive) and use the white wire of the HYFIRE®VIA for triggering, you can
purchase a Chrysler Dual Ballast Resistor (1973-76 applications). Wire
it as shown in Figure 3.
Engine Run-On
If your engine continues to run even when the ignition is turned off,
you are experiencing engine run-on. Usually, older vehicles with an
external voltage regulator are susceptible to this condition. Because
the HYFIRE®VIA Ignition Control receives power directly from the
battery, it does not require much current to keep the unit energized. If
you are experiencing run-on, it is due to a small amount of voltage
going through the charging lamp indicator and feeding the small red
wire (even if the key is turned off).
GM 1973-83 with Delcotron Alternators
GM Delcotron alternators use an internal voltage regulator. Install the
diode inline on the smallest wire exiting the alternator (see Figure 5).
It is usually a brown wire.
Most other applications: To eliminate run-on, place a resistor in-line to
the HYFIRE®VIA small red wire to keep voltage from leaking into the
HYFIRE®VIA Ignition.

FIGURE 3
Early Ford and GM: To solve the run-on problem, a diode is supplied
with the HYFIRE®VIA Ignition Control. By installing this diode in-line
of the wire that goes to the charging indicator, the voltage is blocked
from entering the HYFIRE®VIA Ignition Control. Figure 4 shows the
proper diode installation for early Ford and GM vehicles.
NOTE: Diodes are used to allow voltage to flow only one way.
Make sure the diode is installed facing the proper direction, as
shown in Figure 4.
Ford: Install the diode inline to the wire going to the #1 terminal.
GM: Install the diode inline to the wire going to the #4 terminal.

Misses and Internittent Problems
Experience has shown that if your engine is misfiring or hesitating at
higher RPM, it is usually not an ignition problem. Most common causes
include a coil or plug wire failure, arcing from the cap or boot plug to
ground or spark ionization inside the cap. Perform the following checks:
Inspect the plug wires at the cap and at the spark plug for a tight
connection. Visually inspect for cuts, abrasions, or burns.
Inspect the primary coil wire connections. Because the HYFIRE®
VIA Ignition Control receives a direct 12 volt source from the bat-
tery, there will not be any voltage at the coil positive (+) terminal,
even with the key turned on. During cranking, or while the engine is
running, very high voltage will be present and no test equipment
should be connected.
WARNING: Do not touch the coil terminals during cranking or
while the engine is running.
Make sure that the battery is fully charged and the connections are
clean and tight. If you are not running an alternator, this is an im-
perative check. If the battery voltage drops below 10 volts during a
race, the HYFIRE®VIA Ignition Control output voltage will drop.
Is the engine running lean? Inspect the spark plugs and the entire
fuel system.
Check all wiring connections for corrosion or damage. Remember
to use proper connections followed by soldering, then seal the con-
nections completely.
If everything checks positive, use the procedure below to test the igni-
tion for spark. Mallory also offers an Ignition Tester (PN 28357) that
allows you to check the entire ignition system while it is installed in the
vehicle. This tool also checks operation of RPM limits, activated
switches, and shift lights.
CHECKING FOR SPARK
If triggering the ignition with the white wire:
(See Figure 6)
1. Make sure the ignition switch is in the OFF position.
2. Remove the coil wire from the distributor cap and set the terminal
approximately 1/4" from ground.
3. Disconnect the HYFIRE®VIA Ignition Control white wire from the
distributors points or ignition amplifier.
4. Turn the ignition to the ON position. Do not crank the engine.
5. Tap the white wire to ground several times. Each time you pull the
wire from ground, a spark should jump from the coil wire to ground.
If spark is present, the ignition is working properly. If there is no
spark, skip to Step 6 below.
If Triggering With the Magnetic Pickup:
(See Figure 7)
1. Make sure the ignition switch is in the OFF position.
2. Remove the coil wire from the distributor cap and set the terminal
approximately 1/4" from ground.
3. Disconnect the HYFIRE®VIA Ignition Control magnetic pickup wires
from the distributor.
4. Turn the ignition to the ON position. Do not crank the engine.
5. With a small jumper wire, short the HYFIRE®VIA Ignition Control
green and violet magnetic pickup wires together. Each time you
break this short, a spark should jump from the coil wire to ground.
If spark is present, the ignition is working properly. If there is no
spark skip to Step 6 below.
6. If there is no spark.
A. Inspect all of the wiring.
B. Substitute another coil and repeat the test. If there is now spark,
the coil is at fault.
C. If there is still no spark, check to make sure there is 12 volts on
the small red wire from the HYFIRE®VIA Ignition Control when
the key is in the ON position. If 12 volts is not present, find
another switched 12 volts source and repeat the test.
D. If, after following the test procedures and inspecting all of the
wiring, there is still no spark, the HYFIRE®VIA Ignition Control
is in need of repair. See the Warranty and Service section for
information.
