Ignition Coil: Testing and Inspection
INSPECTIONSecondary coil winding
1. Remove the high-tension leads.
2. Measure resistance of the secondary coil winding of each coil with an ohmmeter.
Secondary coil winding resistance: [at 20 °C ( 68 °F)]: 8.7-12.9 k Ohms
3. If not within the specification, replace the ignition coil.
Insulation resistance of case
1. Remove the high-tension leads and disconnect the connectors.
2. Use a 500 V megger tester to measure the insulation resistance between the primary terminal and the coil case.
Resistance: Above 10 M Ohms
3. If not as specified, replace the ignition coil.
