MaxifuseslRelay Center 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. This greatly reduces the chance of damage caused by electrical problems. Look at the silver-colored band inside the fuse. 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. If you ever have a problem on the road and don't have a spare fuse, you can "borrow" one that has the same amperage. Just pick some feature of your vehicle that you can get along without -- like theradio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can. To check the fuses inthis underhood fuse 'center,turn the twoknobs one-quarter turn counterclockwise and loosen the metal wing nut on the passenger side of the cover. Then remove the cover.
