(5) Timer Relay 2 (With OPC Type)
Connector Voltage
1. Disconnect the connector from the timer relay 2 after turning the

2. Measure the voltage with a voltmeter across the connector 1
terminal and chassis.
3. Measure the voltage with a voltmeter across the connector 2
terminal and chassis.
4. If these voltage differ from the battery voltage, the wiring
harness or main switch is faulty.
• The timer relay 2 shall be installed with a part of connector
dawn ward.
