Distributor Ground Circuit Continuity Check

  1. Disconnect distributor connector from wiring harness. Connect ohmmeter leads to distributor base and Black wire terminal in distributor connector. Measure resistance, then reconnect distributor connector to wiring harness.
  2. If resistance was less than1 ohm, circuit is okay. If resistance was greater than 1 ohm, check ground screw in distributor housing.
