Ignition Coil: Testing and Inspection

1) Remove distributor cap and disconnect distributor coupler.
2) Measure primary and secondary coil circuit resistances.

Ignition coil resistance at 20°C (68°F)
Primary circuit 0.7 - 0.9 Ohms
Secondary circuit 13 - 18 k Ohms

If check result is not satisfactory, replace distributor.
