Light Failure Relay Circuit
- Disconnect the connector from the relay and inspect the connector on the wiring harness side. See CONNECTOR IDENTIFICATION . See INSPECTING LIGHT FAILURE RELAY CIRCUIT table.INSPECTING LIGHT FAILURE RELAY CIRCUIT
Tester Connection Condition Specified Condition 1 - Ground Constant Continuity (1) 2 - Ground Constant Continuity (1) 9 - Ground Constant Continuity (1) 11 - Ground Constant Continuity 3 - Ground Light Control Switch OFF No Voltage 3 - Ground Light Control Switch TAIL Or HEAD B+ Voltage 4 - Ground Ignition Switch LOCK Or ACC No Voltage 4 - Ground Ignition Switch ON B+ Voltage 7 - Ground Stop Light Switch OFF No Voltage 7 - Ground Stop Light Switch ON B+ Voltage 8 - Ground Ignition Switch LOCK Or ACC No Voltage 8 - Ground Ignition Switch ON B+ Voltage (1) There is resistance because this circuit is grounded through the bulb. - If the circuit is as specified, replace the relay. If the circuit is not as specified, inspect the circuits connected to other parts.
