Ignition Coil: Testing and Inspection

1. Turn the ignition switch OFF.
2. Disconnect the four pin connector and ignition coil wire.

Ignition Coil Test:




Ignition Coil Resistance Test:





3. Using an ohmmeter, measure resistance between the terminals. Replace the coil if the resistance is not within specifications.

NOTE: Resistance will vary with the coil temperature; specifications are at 68 °F (20°C).
^ Primary Winding Resistance (between the A and B terminals): 0.6-0.8 ohms.
^ Secondary Winding Resistance (between the A and secondary winding terminals): 14-22 kohms
4. Check for continuity between the A and C terminals. Replace the coil if there is no continuity.
