Headlamp: Description and Operation

Circuit Description.

Low Beam Operation
With the ignition switch in ON and the light switch in HEAD position, battery voltage is applied to the coil of the head lamp relay from fuse 10 and then ground is provided to the coil of the head lamp relay through the light switch. Battery voltage from fusible link (Lamp) is then provided to the Left/Right head lamp through Left/Right head lamp fuses. The low beam head lamp illuminates when the Dimmer/Passing switch is in low position.

High Beam Operation
With the light switch in HEAD position and ignition switch in ON, battery voltage is applied to the head lamp relay coil from fuse 10. The high beam head lamps illuminates when the Dimmer/Passing switch is in FLASH or HIGH position.

Flash Operation
The flash feature works with the light switch in all positions (OFF, PARK or HEAD). With the light switch in OFF or PARK and the head lamp dimmer switch in FLASH, ground is provided to the high beam head lamps through the head lamp dimmer/passing switch.
Battery voltage is applied to the high beam head lamp and the beam indicator, and the high beams and the high beam indicator illuminate as long as the switch is held in the FLASH position.
