Ignition Coil: Testing and Inspection

Connect An Ohm Meter As Shown:

PRIMARY COIL WINDING
1. Unplug 3-pin connector from distributor.
2. Use an ohm meter and measure primary winding resistance.

Resistance: 0.49 - 0.73 Ohms @ 20°C (68°F).

3. If not within specification, replace distributor assembly.

Connect An Ohm Meter As Shown:

SECONDARY COIL WINDING
1. Remove distributor cap.
2. Measure the resistance of the secondary coil winding as shown.

Resistance: 20 - 31 K Ohms @ 20°C (68°F).

3. If not within specification, replace distributor assembly.
