A-12116

Simply attach this device between the distributor cap and the coil wire and it will show you

whether the wires on your coil are connected properly and whether you have sparks or not.

Instructions for use:

The ignition system is designed to "fire" the spark plug with a specific polarity.

Polarity depends on the battery terminals of the coil's primary winding and its relationship to the secondary (high voltage) winding.

Incorrect spark polarity can cause the following

- Hard starting

- Uneven idle speed

- Low engine power

- Lack of power at high speeds

How to use the spark and polarity tester:

1. Install it between the ignition coil high voltage output wire and the distributor cap

and position the indicator light so that you can see it clearly.

a. Tester, with the sleeve protruding into the distributor cap

b. coil wire, into the recessed brass bowl of the tester

2. Start the engine and let it idle at low speed.

3. Flashing light UPPER - ignition and polarity = OK

4. Flashing LOWER lamp - Coil polarity = REVERSED

a. Swap the coil primary cable connections.

b. Repeat steps 2 and 3 above.

5. No flashing light - No spark

a Check all ignition components.

CAUTION:

Only use SPARKLITE between the distributor and coil as specified above.

DO NOT USE IT IN ANY OTHER WAY.
