SMU - SECTION 8A - REVISED SCHEMATIC. Buick Park Avenue 1995

SUBJECT: SERVICE MANUAL UPDATE - SECTION 8A - REVISED SCHEMATIC FOR IGNITION SWITCH AND PARK/NEUTRAL POSITION SWITCH

MODELS: 1995 BUICK LESABRE, PARK AVENUE

THIS BULLETIN REPLACES THE SCHEMATIC FOUND ON PAGE 8A-100-1 OF THE SERVICE MANUAL. THIS REVISED SCHEMATIC INCLUDES WIRING FOR THE IGNITION SWITCH AND THE PARK/NEUTRAL POSITION SWITCH. ALTHOUGH THESE CIRCUITS ARE PRESENT ON THE VEHICLE, THEY WERE NOT SHOWN BECAUSE THEY DO NOT AFFECT THE NORMAL FUNCTION OF THE HEADLAMPS WHEN THE VEHICLE DOES NOT HAVE TWILIGHT SENTINEL OR DAYTIME RUNNING LAMPS. THEIR INPUTS ARE NEEDED ONLY TO INSURE THAT THE HEADLAMPS DO NOT GO OUT IN CASE OF AN OVERVOLTAGE CONDITION WHEN THE IGNITION SWITCH IS IN "RUN" AND THE GEAR SELECTOR LEVER IS OUT OF "PARK". FOR VEHICLES WITH TWILIGHT SENTINEL OR DAYTIME RUNNING LAMPS, REFER TO SECTION 8A-101, TWILIGHT SENTINEL (T82)/DAYTIME RUNNING LAMPS.
