Hazard Warning Lamps: Description and Operation

Voltage is applied at all times through the STOP HAZ Fuse and the Hazard Flasher to the normally open poles of the Hazard Switch. When the Hazard Switch is "ON," voltage is applied to the Front Turn Lights, Turn Indicators, Rear Stop-Turn Lights and the Front Marker Lights. When the Light Switch is "OFF," they will flash when the timing element in the Hazard Flasher heats up, opening and closing the circuit.

If the Light Switch is in "PARK" or "HEAD," the Marker Lights flash on when the Hazard Lights are off, and off when the Hazard Lights are on.

When the Hazard Switch is "ON," the turn circuit is always open, and the Hazard Flasher controls the Lights.

When the Hazard Switch is "ON," the stop light Circuit is always open, so the Hazard Flasher continues to flash the lights even when the Brake Pedal is depressed.
