IGNITION COIL INSPECTION

Primary coil winding
1. Disconnect the ignition coil connector.




2. Measure the resistance between terminal A and B using a tester.
- If not within the specification, replace the ignition coil.

Specification: 0.45-1.15 ohms [25 degrees C {77 degrees F}]

Secondary coil winding

1. Remove the ignition coil.




2. Measure the resistance between terminal A to ignition coil boot socket using a tester.
- If not within the specification, replace the ignition coil.

Specification: 5.0-6.0 kilohms [25 degrees C {77 degrees F}]

Insulation resistance of case

1. Disconnect the ignition coil connector.




2. Measure the insulation resistance between terminal A to ignition coil case using a tester.
- If not as specified, replace the ignition coil.

Specification: 10 megohms or more
