Fuses are primarily used for circuit protection, and the process of changing a fuse for a car radio starts with looking at the fuse panel. Replace a fuse with a new one of the same color with help from an ASE-certified mechanic in this free video on auto repair and car maintenance.
Good afternoon. My name is Tom Brintzenhofe, Certified Master Tech out of Reading, Pennsylvania and today I am going to talk to you a little bit about how to change a fuse for your car radio. I want to talk to you a little bit about fuses and wiring itself before we get into how to change a fuse. Fuses are used primarily for circuit protection. I sincerely vote against wiring anything without a fuse. They are put there for your own protection. If you do take one out and you end up wiring it without a fuse, if there is a problem with an overload on that circuit and it is drawing too much voltage you could actually end up starting a car fire, an electrical fire which is never a good thing so please try to steer away from doing that. The thing I want to talk about if you have a problem with your car stereo and it just doesn't turn on and you can't get it to work at all and your radio clock doesn't work that is a good indication that you might have a blown fuse. You want to find your fuse panel on this jeep, luckily it is right here so you want to pop this open. Sometimes they are a little pain to get open here but you'll have fuses in here ranging anywhere from 5 to 30 amps and when you replace a fuse try to always replace them unless it is an emergency situation with the same amperage because if you have a 5 amp circuit and you end up putting a 15 or 20 amp fuse in it you are going to allow more voltage to through that than you want and again you could turn it into an electrical fire so you want to find your circuit. Most of these fuse panels are all marked on the inside which is what, you just find the fuse that you need for say your car radio and you pull it out and if you see on the inside of it you will notice there is a little metal bridge on the inside and you see that bridge is broken on the middle it will look like it is burnt and then you'll have yourself a burnt fuse. Now you can change it out, always like I said make sure they're all color coded and you can change it with the same color fuse. When you put this fuse back in I just want to say if it blows right when you turn the ignition back on, your radio back on and you have a wiring problem again don't put a bigger fuse in to keep it working but take it to your local garage and try to keep that short figured out before you keep doing it to avoid electrical fire but that is basically all there is to replacing a fuse for your car stereo.
