Ignition Coil: Testing and Inspection

1. Turn the Ignition Switch "OFF".





2. Disconnect the 4 P Connector and Ignition Coil Wire.

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 (2O°C).

Primary Winding Resistance (Between the No. 1 and No. 3 Terminals): 0.6 - 0.8 ohms.
Secondary Winding Resistance (Between the No.1 and Secondary Winding Terminals): 14 - 22 K Ohms.





4. Check for continuity between the No. 1 and No. 2 Terminals. Replace the Coil if there is no continuity.
