Distributor Ground Circuit Continuity Check
- Disconnect distributor connector from wiring harness. Connect ohmmeter leads to distributor base and to Black wire terminal in distributor connector. On front wheel drive models, the wire color cannot be seen without removing connector hold-down plate. Measure resistance, then reconnect distributor connector to wiring harness.
- If resistance was less than 1 ohm, circuit is OK. If resistance was greater than 1 ohm, check ground screw in distributor housing.
