Exterior Lamps

PARK, MARKER, TAIL AND LICENSE LIGHTS

Voltage is applied at all times from Fuse 14 to the Headlight Switch and, if equipped, to the Twilight Sentinel Module from CKT 240. With the Headlight Switch in "PARK" or "HEAD" or with low light conditions if equipped with Twilight Sentinel, 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 Lights. 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 LIGHTS

With the Ignition Switch in "RUN," "BULB TEST" or "START," voltage is applied from Fuse 18 and the Turn Flasher to the normally closed pole of the Hazard Switch in the Turn/Hazard Switch Assembly. With the Turn Switch in the "TURN LEFT" position, voltage is applied from the Turn Switch to CKT 14 at terminal "H" of the Turn/Hazard Switch connector C210 and to CKT 18 at terminal "M" of C210. LH Front Turn, Rear Turn and Indicator Lights flash "ON" and "OFF" as current flow heats up the timing element in the Turn Flasher, and it continuously opens and closes the circuit (for RH Turn Lamps CKT 15 terminal "J" of C210 and CKT 19 terminal "N" of C210).
With Park Lights "ON" and Turn Lights "ON," voltage is applied to both terminals of the Front Marker Lamp causing it to be "OFF." When the Front Turn Lamp is "OFF," voltage is applied to only one terminal of the Marker Lamp causing it to flash "ON." They continue to flash "ON" and "OFF" out of sequence until Turn Switch is turned "OFF."

HAZARD LIGHTS

Voltage is applied at all times from Fuse 19 and the Hazard Flasher to the normally open poles of the Hazard Switch in the Turn/Hazard Switch Assembly. With the Hazard Switch in "HAZARD," voltage is applied to the Stop-Turn Lights. All of the Stop-Turn Lights and both Turn Indicators flash on and off.

STOP LIGHTS

Voltage is applied at all times from Fuse 19 to the Brake Light Switch. When the brake pedal is depressed, voltage is applied from the Brake Light Switch and Turn/Hazard Switch to CKT 18 and CKT 19, turning "ON" the LH and RH Tail/Stop/Turn Lights. Voltage is supplied at all times through Fuse 19 to the Brake Light/Cruise Release Switch. When the brake pedal is depressed, voltage is applied from the Brake Light/Cruise Release Switch to CKT 820 and the CHMSL, turning "ON" the CHMSL. CHMSL is not affected by the Turn/Hazard Switch Assembly.
