Ignition Coil: Testing and Inspection

Ignition Coil Inspection

1. Remove air cleaner hose.
2. Disconnect high-tension cords and ignition coil connectors from ignition coils.





3. Inspect primary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.

Primary coil resistance:
Cold: 0.67-1.05 ohms
Hot: 0.85-1.23 ohm

If the resistance is not as specified, replace the ignition coil.
4. Remove ignition coils.





5. Inspect secondary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.

Secondary coil resistance:
Cold: 9.3 - 16.0 K ohms
Hot: 11.7 - 18.8 K ohms

If the resistance is not as specified, replace the ignition coil.
6. Reinstall ignition coils.
7. Reconnect ignition coil connectors and high-tension cords.
8. Reinstall air cleaner hose.
