Without Daytime Running Lamps

CIRCUIT OPERATION

HEADLIGHTS
Voltage is applied to the Headlight Switch at all times from Fusible Link Z. When the Headlight Switch is in HEAD," voltage is applied directly from the Headlight Switch through CKT 10 to the LO Beam Headlamps. Voltage is also applied through CKT 10 to the Headlight Dimmer Switch. When the Headlight Dimmer Switch is placed in "'HI," voltage is applied through the closed contacts of the Dimmer Switch to the HI Beam Headlamps and the HI Beam Indicator. When HI Beams are selected both the LO Beam Headlamps and HI Beam Headlamps will be illuminated. The LO Beam Headlamps, HI Beam Headlamps, and HI Beam Indicator are permanently grounded so that when battery voltage is applied, the lamps operate.

FOG LIGHTS
With the Headlight Switch in "HEAD" or "PARK," voltage is applied to one side of the Fog Light Switch. When the Fog Light Switch is closed, voltage is applied to one side of the Fog Lights Relay Coil, energizing the relay (the other side of the coil is grounded through the HI Beam Filament of the Headlamps).

When energized, the normally open contacts of the Fog Lights Relay close, allowing voltage to be applied to the Fog Lights.

When the HI Beams are activated, ground is removed to one side of the Fog Lights Relay Coil, de energizing the relay and turning off the Fog Lights.
