Ignition Coil: Testing and Inspection

Fig. 1 Testing Coil Resistance:

1. Disconnect ignition coil harness connector.
2. Using a suitable ohmmeter, measure resistance between terminals 1 and 2, resistance should be approximately 1.00 ohm, then measure resistance between terminals 1 and 3, resistance should be approximately 10,000 ohms, Fig. 1.
3. If not as specified, replace coil.
