Checking and Replacing Fuses

The wiring circuits in your vehicle are defended from short circuits by a combination of fuses and also circuit breakers. This significantly reduces the chance of fires resulted in by electric problems.

Look in ~ the silver-colored band inside the fuse. If the tape is broken or melted, change the fuse. Be sure you change a negative fuse through a new one of the the same size and rating.

If you ever before have a problem on the road and also don’t have a preventive fuse, you deserve to borrow one that has actually the exact same amperage. Just pick some function of your car that you can acquire along there is no – favor the radio or cigarette lighter – and also use that is fuse, if that is the exactly amperage. Replace it as quickly as you can.


Note

Before instead of a fuse examine that the vital has been gotten rid of from the ignition and also that every the solutions are switched turn off and/or disengaged.Do no repair fuses and never replace a swollen fuse through one that has a greater amp rating. This can cause damage to the electric system and also fire.Never change a damaged fuse with anything other than a new fuse. Use always an undamaged fuse the the exact same color.If a fuse blows again contact authorized servicesSpilling fluid on any type of electrical ingredient on the automobile may damage it. Always keep the consist of on any electrical component.
