INSTALLATION INSTRUCTIONS

FORM 1051 (REV. A) 10/01

Battery

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

stock coils or aftermarket coils designed as stock replacements.

Tachometers

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

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.

Foreign Vehicles

Because of modern fuel injection systems, some foreign vehicles may

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

vides a good path for the spark to follow while minimizing electromag-

netic interference (EMI).

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.
