TEST PROCEDURE

1) Remove the cap and rotor. Turn the ignition ON and test

voltage at the NEGATIVE side of the coil (black lead of

meter to ground and red lead of meter to coil NEGATIVE

post). Voltage should read 12 volts.

2) If battery voltage is present, place a credit card, drivers

license, business card or similar and block the photo

optics of the module. The voltage should drop to 2 volts

or less (1 to 2 volts). If this test is positive, then the

module is working.

3) If the test results are as follows:

a) Voltage does not drop, module is open and must

be replaced. This may have been caused by a power

surge, high resistance in the plugs or plug wires, or

improper ground. Possible charging system load

dump.

b)Voltage always stays below 2. 0 volts. The module

has been spiked by high voltage or amperage, lack

of ballast resistor, or improperly wired.

c) Voltage only drops to 3-4 volts could produce a weak

spark.

Possible causes are:

 Faulty charging system (stuck or shorted regula-

tor/alternator)

 Faulty starting system (starter drag)

 Non-suppression spark plug wires (copper or stain-

less core wires). Spark plug wires must be carbon

core or spiral wound plug wires.

 Large amperage alternator

 High amp stereo equipment

 CB radio

 Direct shorts in the ignition or electrical system

 Trying to start motor with battery charger hooked

 Welding on the vehicle with the distributor hooked

up (disconnect 3-wire plug of the distributor before

welding)

 Faulty or improper ground of module

If you must replace the module, replace it with Mallory

Part No. 605.
