Ignition Coil: Testing and Inspection

1. With the ignition switch OFF, remove the distributor ignition cap.





2. Remove the two screws to disconnect the BLK/YEL and WHT/BLU wires from the terminals A (+) and B (-) respectively.





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 A and B terminals): 0.6 - 0.8 Ohms

Secondary Winding Resistance
(Between the A and secondary winding terminals): 12.8 - 19.2 kOhms
