Headlamps

Battery voltage is applied to the headlamp switch at all times through circuit 442. When the headlamp switch is in the HEAD position, voltage is applied to headlamp dimmer switch and to the DRL control module through circuit 10. When the DRL control module receives voltage on circuit 10, it disengages the DRL function. When the headlamp dimmer switch is placed in the LOW position, battery voltage is applied to the low beam headlamps through circuit 12. When the headlamp dimmer switch is placed in the HIGH position, battery voltage is applied to the high beam head lamps and to the DRL control module through circuit 11. When the DRL control module receives the voltage on circuit 11, it apples voltage to circuit 629 which turns on the high beam indicator in the instrument cluster.
