Timer Relay Connector Voltage
1. Measure the voltage with a voltmeter across the Red / White
terminal (2) and chassis.
2. Turn the main switch on, and measure the voltage across the
Yellow terminal (3) and chassis.
3. If these voltages differ from the battery voltage, the wiring
harness or main switch is faulty.

Test of Timer Relay
1. Remove the timer relay.
2. Connect the jumper leads across the battery terminal and the
Red / White terminal (1), and across the battery positive
terminal and the Yellow terminal (2).
3. Connect the jumper lead across the battery negative terminal
and the Black terminal (4), and across the battery negative
terminal and the Blue terminal.
4. Connect the jumper lead across the Red terminal (3) and the
bulb terminal.
5. The bulb lights up when disconnecting the jumper lead from the
Red / White terminal (1) 0.7 to 1.3 seconds, the timer relay is
proper.
