Pick-Up Coil: Testing and Inspection

Testing The Pickup Coil:

TOOL REQUIRED
J 39200 Digital Multimeter.


INSPECTION
Make sure the ignition switch is "OFF."

1. Remove the distributor cap.
2. Disconnect the pickup coil connector from the Ignition Control Module (ICM).
3. Test the resistance of the coil with J 39200.
A. Connect J 39200 to either pickup coil lead and the housing as shown (1) in the image. The reading should be OL (infinite). If not, replace the coil.
B. Connect J 39200 to both pickup coil leads, (2) in the image. Flex the leads by hand at the coil and the connector to locate any intermittent opens. J 39200 should read a constant value in the 500 to 1500 ohm range. If not, replace the coil.
