Why is an electrical fuse burnt?
An electrical fuse would look "burnt" if something in the circuit it is protecting has developed a fault which caused a current overload situation to occur.
In other words, something caused the current flowing through the fuse to exceed its normal rated maximum current value so much that the fuse did what it was designed to do!
In this situation, if a new fuse of the same value immediately blows, do not attempt to replace it by a fuse having a higher rated current value. The correct procedure is to find out what went wrong in the circuit that the fuse is protecting and then get the problem fixed so that the equipment works properly again without blowing a new fuse having the same rated current value as the original fuse which looked burnt.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

When trying to start your 1998 Chevrolet Silverado it will not turn over and there is no power at all?
Don't panic its a fuse that's located in your fuse box under the hood marked Tail. Its marked 15, take it out look at the center of it and see if it is burnt out. If it is replace it and all should be fine. IF you have any other issues and it doesn't work take it to a qualified mechanic it may be a electrical issue.
Burnt out, blown, open etc ! First, this occured because the listed current rating, i.e. 30a, 10a, 15a, etc, has been exceeded for some reason. First take the fuse out and If the fuse has a clear case, color or not, you can see whether or not the metal strup inside is burnt in two or "open". The fuse can be "open" up at one end where you can't see it (older fuse) or you…
My 1984 Nissan pickup will not charge the battery. I have replaced the alternator and put in a new battery.?
Dash lights and tail lights usually work off the same fuse. Some vehicles have two fuse panels, one inside usually under the dashboard and another inder the hood. If the fuse is good, the problem may be a bad connection or burnt wire at the fuse block. "Jump" the leads where the fuse fits into. If you still have no lights, there is a bad connection or burnt wire. If you get lights, the fuse…
There is a fuse box inside the car, to the lower left of the steering wheel, by the door. Pop off the panel, and look at the back of the panel, which has a color coded chart showing which fuse does what. Or- you could just pull each fuse out and replace them one at a time, while looking for a burnt out one. I didn't even know I had a fuse box inside my…
