Electrical System Add-on Electrical Equipment Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links inthe wiring itself. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside thefuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. Spare fuses are located in the Instrument Panel Electrical Center. See "Underhood Electrical Center" in the Index. NOTICE: Don't add anything electrical to your Pontiac unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn't be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an air bag system. Before attempting to add anything electrical to your Pontiac, see "Servicing Your Air Bag-Equipped Pontiac" in the Index. Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the underhood electrical center. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp system checked right away. 6-66
