Checking Head Light Function
1. Measure the resistance with an ohmmeter across B4 terminal
and T terminal, B4 terminal and 1 terminal, B4 terminal and 2
terminal when head light switch is at "OFF" position.
2. Measure the resistance with an ohmmeter across B4 terminal
and T terminal, B4 terminal and 1 terminal, B4 terminal and 2
terminal when head light switch is at "ON (LOW)" position.
3. Measure the resistance with an ohmmeter across B4 terminal
and T terminal, B4 terminal and 1 terminal, B4 terminal and 2
terminal when head light switch is at "ON (HIGH)" position.
4. If measured value is different from table below, the combination
light switch is damaged.
