Ignition Coil: Testing and Inspection

1. Turn the ignition switch OFF, and remove the distributor ignition (DI) cap.

2. Remove the two screws to disconnect the BLK/YEL and WHT/BLK wires from 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 (20° C)

Primary Winding Resistance
(Between the A and B terminals):
0.45-0.6 Ohms
Secondary Winding Resistance
(Between the A and secondary winding terminals):
22-34 kOhms
