Checking and Replacing Fuses
Fuses protect the car’s electrical systems from short circuits. To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.
Fuses of the same amperage can be temporarily borrowed from another fuse location if a fuse goes out. Replace the fuse as soon as possible.
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload.
- If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.
