Circuit Operation

Battery voltage is applied to the Headlamp Switch at all times through circuit 442. When the Headlamp Switch is in HEAD, voltage is applied directly to Headlamp Dimmer Switch through circuit 10. When the Headlamp Dimmer Switch is placed in LO, battery voltage is applied to the LO Beam Lamps through circuit 12. When the Headlamp Dimmer Switch is placed in HI, battery voltage is applied to the HI Beam Lamps and HI Beam Indicator through circuit 11.
