What causes a fuse to short?
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. A mis-wired lamp, for example, can cause a short circuit and blown fuse if it is plugged into an outlet.

What should I do if I Blew my Fuse?
The Fix: Make sure the faulty device is unplugged and there is no damage to the outlet. First, test the circuit. Then check for any damage on or around the electrical panel. If you see any damage, call an electrician before doing anything else with it. If there is none, flip the breaker switch back to its operating position.
Why does my battery fuse keep blowing out?
Most likely your arcing somewhere, you said you seen spark on the alternator, look at the main power wire that connects to the stud on the alternator, make sure theres that rubber/plastic washer behind it and that its not arcing on anything, that’d be my guess. Done any ghettofied wiring jobs lately?
How can you tell when a fuse has been blown?
You might be wondering, then, how to tell if a fuse is blown–an actual fuse, that is. You will see that the fuse has melted, and there might be charring on the panel. A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge” ).
Why did the fuse blow on my fog light?
Well, there was a thirty amp fuze in for the fog lights when it only called for a 15 amp, so, naturally, when the fuze tried to blow because of the short, it couldn’t, and the wires got so hot, it followed the entire engine wiring harness, and melted and burnt wires together.
