Exterior Lamps

PARK, MARKER, TAIL AND LICENSE LAMPS
Voltage is applied at all times through the Tail Fuse to the Headlamp/I/P Dimmer Switch through CKT 240. With the Headlamp/I/P Dimmer Switch in "PARK" or "HEAD" voltage is applied to CKT 9. Current flows through CKT 9, to all Park, Marker, Tail and License Lamps turning them on. The only lamps that see a current from CKT 9 and do not turn on are the turn filaments in the Park/turn Lamps. They do not turn on because the voltage drop across the Front Side Marker Lamps is much higher than that across the Turn Lamp Filaments.

TURN LAMPS
With the Ignition Switch in "RUN," "BULB TEST" or "START," voltage is applied through the TURN B/U fuse and Turn Signal Lamp Flasher to the normally closed pole of the Hazard Switch in the Turn Signal Switch Assembly.

With the Turn Signal Switch in the "TURN LEFT" position, voltage is applied from the Turn Signal Switch through CKT 14 to the LH Front Marker Lamp, LH Front Park/Turn Lamps and the LH Turn Indicator Lamp and also through CKT 18 to the LH Tail/Stop/Turn Lamps. The Lamps flash on and off as current flow heats up the timing element in the Turn Signal Lamp Flasher, and causing it to continuously open and close the circuit. The "TURN RIGHT" position works in a similar way through CKT 15 and CKT 19 to the RH Turn Lamps.

With Park Lamps on and Turn Lamps on, voltage is applied to both terminals of the Front Marker Lamp causing it to be off. When the Turn Lamps are off, voltage is applied to only one terminal of the Marker Lamp causing it to flash on. The Marker and Park/Turn Lamps continue to flash on and off alternately until Turn Switch is turned off.

HAZARD LAMPS
Voltage is applied at all times through the STOP-HAZ Fuse and the Hazard Flasher to the normally open poles of the Hazard Switch in the Turn Signal Switch Assembly. With the Hazard Switch in "HAZARD," voltage is applied to the Stop-Turn Lamps. All of the Stop-Turn Lamps and both Turn Indicators flash on and off.

STOP LAMPS
Voltage is applied at all times through the STOP-HZ Fuse to the Stoplight Switch. When the brake pedal is depressed, voltage is applied through the Stoplight Switch and Turn Signal Switch to CKT 18 and CKT 19, turning on the LH and RH Tail/Stop/Turn Lamps.
