Ignition Coil Resistance
- Disconnect 3-wire connector from ignition coil assembly. Using an ohmmeter, check primary resistance between terminals No. 1 and 2 for one coil. See Fig 1 .
- Check primary resistance between terminals No. 2 and 3 for remaining coil. Resistance should be as specified. See IGNITION COIL RESISTANCE table. If resistance is not as specified for each coil, replace ignition coil assembly.
- To test secondary resistance, connect one ohmmeter lead to tower at one end of coil. Connect remaining ohmmeter lead to tower at opposite end of same coil.
- Repeat test for other coils. If resistance of each coil is not as specified, replace ignition coil assembly.
