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

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. We also recommend non-resistor spark plugs.
Wires should be routed away from sharp edges, moving objects, and
heat sources. Wires that are next to each other in the engines firing

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

hicle that is originally equipped with a CD ignition control.
