Distributor Pick-Up Coil Check

  1. Turn ignition switch "OFF". Disconnect harness connector from control unit. Connect ohmmeter leads to connector cavities No. 4 and 5. See Fig 1. Ohmmeter reading should be 150-900 ohms. If reading is not to specifications, make same check at distributor 2-wire connector. If reading is still not correct, replace defective pick-up coil assembly. If correct reading is found at distributor connector, but not at control unit connector cavities No. 4 and 5, replace or repair harness.
