Battery
The HYFIRE^® V 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^® V Ignition Control, we
recommend Mallory’s PROMASTER^® Coil P/N 29440. Mallory’s
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 Mallory’s PROMASTER^® Coil P/N 28880.
Tachometers
The yellow wire on the HYFIRE^® V Ignition Control provides a trigger
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^® V Ignition Control. If your GM vehicle uses
an inline filter, it may cause the tach to drop to zero on acceleration. If
this occurs, bypass the filter. For more information on tachometers,
see page 4.
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 manufacturer’s 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. We also recommend non-resistor spark plugs.
Spark Plug Wires
High quality, spiral wound wire and proper routing are essential to the
operation of the HYFIRE^® V 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^® V
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 engine’s 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.
Foreign Vehicles
Because of modern fuel injection systems, some foreign vehicles may
require a tachometer/fuel injection adapter to work with the HYFIRE^®
V Ignition Control.
NOTE: Do not install the HYFIRE^® V Ignition Control in any ve-
hicle that is originally equipped with a CD ignition control.
