Exterior Lamps

CIRCUIT OPERATION

Park Lamps
The coil of the Taillamp Relay is supplied with voltage at all times. When the Light/Turn Signal Switch is in PARK or HEAD, a ground path from G200 is supplied to the coil of the Taillamp Relay. With both power and ground supplied to the Taillamp Relay, the coil energizes and pulls the contacts closed. Voltage flows through the Tail Fuse to all of the Park Lamps. When power and ground are supplied to the Park Lamps, they light.

Turn Lamps
With The Ignition Switch in "ON" or "START", voltage flows from the TURN Fuse through the normally closed contacts of the Hazard Switch to the Turn/Hazard Flasher. The Turn/Hazard Flasher is grounded at G200. The Turn/Hazard Flasher contains a solid state timer/relay. When the Light/Turn Signal Switch is in the LH or RH Turn position, the solid state timer/relay receives a ground signal through the LH or RH Turn Lamps. When the timer/relay receives this signal, voltage flows through the Turn/Hazard Flasher and the Light/Turn Signal Switch to the LH or RH Front and Rear Turn Lamps and LH or RH Turn Indicator. The LH and RH Front and Rear Turn Lamps are all permanently grounded. Depending on The Light/Turn Signal Switch position (LH or RH Turn position), the LH or RH Turn Lamps and LH or RH Turn Indicator will flash approximately 80-90 times per minute.

Hazard Lamps
The HAZ-HORN Fuse receives voltage at all times. When the Hazard switch is pressed to ON, voltage is applied through its closed contacts from the HAZ-HORN Fuse to the Turn/Hazard Flasher. The Turn/Hazard Flasher is grounded at G200. The Turn/Hazard Flasher contains a solid state timer/relay. When the Hazard Switch is pressed to ON, the solid state timer/relay receives a ground signal through the LH and RH Front and Rear Turn Lamps. When the timer/relay receives this signal, voltage flows through the Turn/Hazard Flasher and the Hazard Switch to the LH and RH Front and Rear Turn Lamps along with the LH and RH Turn Indicators. The LH and RH Front and Rear Turn Lamps are all permanently grounded. The solid state timer/relay will flash the Turn Lamps approximately 80-90 times per minute.

Stoplamps
The STOP Fuse is supplied with voltage at all times. When the Brake Pedal is depressed, voltage is applied through the Stoplamp Switch to the LH Stoplamp, RH Stoplamp and the Center High Mounted Stoplamp. All of the Stoplamps are permanently grounded. When power and ground are supplied to the Stoplamps, they light.
