Headlamp: Description and Operation
HEADLIGHTSVoltage is applied to the Headlight Switch at all times from Fusible Link Z. When the Headlight Switch is in "HEAD," voltage is applied to the HI and LO Beam Circuits through the Headlight Dimmer Switch. At the same time, this voltage is applied to the Headlamp Door Motor Assemblies, which allows the doors to open. When the Headlight Switch is moved to "HEAD" and the Headlight Dimmer Switch is placed in "LO," voltage is applied through the closed contacts of the Headlight Dimmer Switch to the LO Beam Circuit of the Headlights. When the Headlight Dimmer Switch is placed in "HI," battery voltage is applied to the HI Beam circuit of the Headlights, 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.
