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 you’re 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

deterrent kill switch. See Figure 2.

White Wire Trigger

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

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.

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.

TROUBLESHOOTING

This section offers several tests and checks you can perform to en-

proper installation and poor connections. You can eliminate many prob-

lems by checking these items. If you have any questions concerning

vice Department at 775-882-6600, Monday through Friday, 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-

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

may need a Mallory tach adapter. Before purchasing a tach adapter,

try connecting your tachometer trigger wire to the yellow wire of the

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

this adapter.

PN 29074

If your tach was triggered from the coil negative termi-

nal (voltage trigger) and you are using the white wire

Ballast Resistor

If you have a current trigger tach (originally connected to coil (+) posi-

purchase a Chrysler Dual Ballast Resistor (1973-76 applications). Wire

it as shown in Figure 3.
