AC 120 V Power Output Circuit

AC 120 V POWER OUTPUT CIRCUIT

Diagnosis Procedure
1.CHECK HARNESS BETWEEN INVERTER UNIT AND AC 120 V OUTLET
1. Turn ignition switch OFF.
2. Disconnect inverter unit connector and AC 120 V outlet connector.
3. Check for continuity between the inverter unit harness connector and AC 120 V outlet harness connector.

4. Check for continuity between inverter unit harness connector and ground.

5. Check for continuity between inverter unit harness connector.

Is the inspection result normal?
YES - GO TO 2.
NO - Repair or replace the harnesses or connectors.
2.CHECK INVERTER UNIT OUTPUT SIGNAL
1. Connect inverter unit connector and AC 120 V outlet connector.
2. Turn ignition switch ON.
3. AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)
4. Check voltage between inverter unit harness connector.

CAUTION:
- To measure AC 120 V output signal, always use the circuit tester AC range.
- Never allow the probes to contact each other.
Is the inspection result normal?
YES - GO TO 3
NO - Replace inverter unit.
3.CHECK AC 120 V OUTLET VOLTAGE
1. AC 120 V outlet main switch ON. (AC 120 V outlet main switch indicator ON)
2. Check voltage between AC 120 V outlet.
