Resistance Test

INSPECTION
Secondary coil winding
- Remove the high-tension leads.
- Measure resistance of the secondary coil winding of each coil with an ohmmeter.





Secondary coil winding resistance: 8.7 - 12.9 kohms @ 20°C (68°F)

- If not within the specification, replace the ignition coil.

INSULATION RESISTANCE OF CASE
- Remove the high-tension leads and disconnect the connectors.




- Use a 500 V megger tester to measure the insulation resistance between the primary terminal and the coil case.

Resistance : Above 10 M ohms


- If not as specified, replace the ignition coil.
