Stop Lights

Voltage is applied at all times from I/P Fuse #37 to the Stoplamp Switch. When the brake pedal is depressed, voltage is applied from the Stoplight Switch and Turn Signal Switch to CKT 18 and CKT 19, turning "ON" the LH and RH Tail/Stop/Turn Lights.

Voltage is supplied at all times through I/P Fuse #37 to the Stoplamp/Cruise Release Switch. When the brake pedal is depressed, voltage is applied from the Stoplamp/Cruise Release Switch to CKT 17 and the CHMSL, turning "ON" the CHMSL.

Buick Wagons with Remote Keyless Entry (AUO) have a 400 ohm resistor in CKT 17 and CKT 750. This Resistor is used to prevent accidental locking of the door locks in cases where the Hazard Switch has been activated and the rear glass is released. Residual voltage in CKT 17 could cause the Remote Control Door Lock Receiver to activate a Door Lock Cycle. The 400 ohm resistor will keep CKT 17 "LOW," thus preventing an unwanted Lock Cycle.
