Circuit Operation

Each headlamp is individually fused so that battery voltage is applied to the individual lamps at all times through circuit 1640 for the LH headlamps and through circuit 1740 for the RH headlamps. When the headlamp switch is in HEAD, the ground is applied directly to headlamp dimmer switch through circuit 1750. When the headlamp dimmer switch is placed in LO, the ground is applied to the LO beam lamps through circuit 1201. When the headlamp dimmer switch is placed in HI, the ground is applied to the HI beam lamps and HI beam indicator through circuit 1200. The high beam indicator is fused so that battery voltage is applied at all times through circuit 640.
