Circuit Operation

Voltage is applied at all times to the Head/Park Lamp Switch through the Headlamp Circuit Breaker. With the Head/Park Lamp Switch in "HEAD," voltage is applied to the coil of the Headlamp Relay which is permanently grounded to G201. The coil is energized and the contacts close providing voltage to the Headlamp Dimmer Switch. When the Headlamp Dimmer Switch is in the "LO" position, the LH and RH Low Beam filaments light. When the Headlamp Dimmer Switch is in the "HI" or "FLASH" position, the LH and RH High Beam filaments light.
