Ignition Coil: Testing and Inspection

Fig. 3 Distributor Connectors:

Measure primary coil resistance at the 2 pin distributor connector. Resistance should be between 0.6 and 0.8 ohms.

Measure secondary coil resistance between the coil tower and each terminal of the 2 pin distributor connector. Resistance should be 12k to 18k ohms.
