CIRCUIT OPERATION

Front Turn Lights
With the Ignition Switch in RUN, BULB TEST, or START, voltage is applied through the TURN B/U Fuse and the Turn Flasher to the normally closed pole of the Hazard Switch in the Turn-Hazard Switch Assembly.

With the Turn Switch in LEFT, voltage is supplied to the LH Turn Indicator and the LH Front Park-Turn Light through the Turn-Hazard Switch Assembly. The LH Turn Indicator and the LH Front Park-Turn Light is fed through the LT BLU wire. The light begins to flash when the current flow heats up the timing element in the Flasher, and it repeatedly opens and closes the circuit. Circuit operation is similar with the Turn Switch in RIGHT.

Rear Turn Lights
With the Ignition Switch in RUN, BULB TEST, or START, voltage is applied through the TURN B/U Fuse and the Turn Flasher to the normally closed pole of the Hazard Switch in the Turn-Hazard Switch Assembly. With the Turn Switch in LEFT, voltage is then supplied to the Rear Tail/Stop-Turn Lights. The lights begin to flash when the current flow heats up the timing element in the Flasher, and it repeatedly opens and closes the circuit.

If the Brake Switch is closed at the same time that the Turn Switch is in LEFT, the LH Rear Tail/Stop-Turn Lights continue to flash through the Turn Flasher. The RH Rear Tail/Stop-Turn Lights come on steadily as long as the Brake Switch is closed. With the Turn Switch in RIGHT, circuit operating is similar.

Rear Marker/Tail/License/Front Marker/Front Park Lights
Voltage is applied through the TAIL Fuse to the Light Switch contacts at all times. With the Light Switch in PARK or HEAD, voltage is applied through the Light Switch to all of the lights in this circuit.

Hazard Lights
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 in HAZARD, voltage is applied to the Front Park-Turn Lights, Turn Indicators, and Rear Tail/Stop-Turn Lights. The lights will flash when the timing element in the Hazard Flasher heats up, opening and closing the circuit. When the Hazard Switch is in HAZARD, the turn circuit is always open, and the Hazard Flasher controls the lights.

Stop Lights
Voltage is applied at all times through the STOP HAZ Fuse to the Brake Switch. When the brake pedal is depressed, voltage is applied through the STOP HAZ Fuse, Brake Switch, and Turn-Hazard Switch Assembly to the Stop Lights. They remain on as long as the brake pedal is depressed.

If the Hazard Switch is in HAZARD, the lower Stop Lights will continue to flash when the brake is applied. The High Level Stop Light will light steadily; however, since it is fed directly from the Brake Switch.
