2) Tail Terminals
1. Turn the main switch ON, and measure the voltage with
voltmeter across the 7 terminal (1) and 3 terminal (3), and
across the 5 terminal (2) and 3 terminal (3).
2. If the voltage differs from the battery voltage, the wiring
harness or switches for tail lights are faulty.
3) Brake Light Terminals
1. Turn the main switch ON, and measure the voltage with
voltmeter across the 6 terminal (1) and 3 terminal (2).
2. If the voltage differs from the battery voltage, the wiring
harness or switch for brake lights are faulty.
