Circuit Operation - Exterior Lights
PARK LAMPSThe coil of Light 1 Relay is supplied with voltage at all times. When the Light Switch is turned to the "PARK" or HEAD" position, a ground path from G201 is supplied to the coil of Light 1 Relay. With both power and ground applied to the coil of Light 1 Relay, the coil energizes and pulls the contacts closed. Voltage is applied 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 the "ON" or "START" positions, voltage is applied from the BACK Fuse through the normally closed contacts of the Hazard Switch to the Turn Relay. The Turn Relay is grounded through the Junction Block at 6203. The Turn Relay contains a solid state timer/relay. When the 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 is applied through the mm Relay and the 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 Turn Signal Switch position LH or RH turn position), the LH or RH mm Lamps and LH or RH Turn Indicator will flash approximately 80-90 times per minute.
HAZARD LAMPS
The HAZARD Fuse receives voltage at all times. When the Hazard Switch is pressed to ON, voltage is applied through its closed contacts from the HAZARD Fuse to the Turn Relay. The Turn Relay is grounded through the Junction Block at G203. The Turn Relay 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 is applied through the Turn Relay 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 closed contacts of the Stoplamp Switch to the LH Stoplamp, RH Stoplamp and Center High Mounted Stoplamp. All of the Stoplamps are permanently grounded. When power and ground are supplied to the Stoplamps, they light.
