With Remote Coil

Fig 1 Testing Remote Coil:

1. Remove distributor rotor, then disconnect pickup coil leads from module.
2. Connect ohmmeter as shown in Figs. 1, step 1. Connect a suitable vacuum source to vacuum advance chamber (if equipped) and note ohmmeter reading throughout entire vacuum advance range. If no vacuum advance is used, flex leads by hand to check for opens. Ohmmeter should read infinite at all times. If not, pickup coil is defective and must be replaced.
3. Connect ohmmeter as shown in Figs. 1, step 2. Repeat step 2. Ohmmeter should read one steady value between 500-1500 ohms. If not, pickup coil is defective and must be replaced.

NOTE: Ohmmeter may deflect if vacuum advance range causes timing core teeth to align. This is not to be considered a defect.
