Wiring Harness & Connector
NOTE:
Ensure ignition is off when removing or installing wiring connector.
- Remove wiring connector from control unit. Use adapter or jumper wires to connect wiring connector to control unit for testing purposes. Turn ignition switch on and connect negative lead of voltmeter to a good ground.
- Connect positive lead to terminal No. 1 of wiring harness connector. See Fig 1. Reading should be within one volt of battery voltage with all accessories off.
- If voltage is not within limits, check wire between terminal No. 1 at connector and ballast resistor. Also check wire between ballast resistor and ignition switch (Ign. 1 connection) and wire between ignition switch, ammeter, and battery. See Figure.
- Connect positive lead to terminal No. 2 at wiring harness connector. Reading should be within one volt of battery voltage with all accessories off. If voltage is not within limits, check wire from terminal No. 2 at connector to negative side of coil.
- Also check wire between positive side of coil to ballast resistor. Check wire between ballast resistor and ignition switch (Ign. 1 connection) and wire between ignition switch, ammeter, and battery. See Figure.
- Connect positive lead to terminal No. 3 at wiring harness connector. Reading should be within one volt of battery voltage with all accessories off. If voltage is not within limits, check wire between terminal No. 3 at connector and ballast resistor.
- Also check wire between ballast resistor and ignition switch (Ign. 1 connection) and wire between ignition switch, ammeter, and battery. See Figure.
