Headlamps

Voltage is applied to the Headlamp Switch at all times from Fusible Link Z. When the Headlamp Switch is in "HEAD," voltage is applied to the HI and LO Beam Circuits through the Headlamp Dimmer Switch. At the same time, this voltage is applied to the Headlamp Module, which actuates the Headlamp Door Motors and allows the Headlamp doors to open. When the Headlamp Switch is moved to "HEAD" and the Headlamp Dimmer Switch is placed in "LO," voltage is applied through the closed contacts of the Headlamp Dimmer Switch to the LO Beam Circuit of the Headlamps. When the Headlamp Dimmer Switch is placed in "HI," battery voltage is applied to the HI Beam circuit of the Headlamps, and the HI Beam Indicator. The LH Headlamp, RH Headlamp, and the HI Beam Indicator are permanently grounded so that when battery voltage is applied, the lamps operate.
