What causes a fuse to blow on a blower motor?
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.

What happens if you put a penny in a burned out fuse?
Tales are told of people who replaced burned-out fuses with a copper penny inserted into the fuse socket—a solution that did restore power to the circuit but also created an immediate danger of fire since there was no longer any limitation to how much power was drawn through the circuit wires.
What happens when a fuse blows-the spruce?
The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or “blows,” and the circuit goes dead. The face of the fuse has a small glass window through which you can see the metal ribbon, and when a fuse blows, you will see the metal ribbon melted through, or a cloudiness in the glass.
Why is blowing a fuse a safety precaution?
It’s important to remember that the blowing of a fuse, or the tripping of a circuit breaker, is actually a built-in safety precaution for your home that disrupts electrical flow and helps to prevent overloaded wiring from causing a fire. What may seem like a nuisance or an inconvenience is actually helping to keep your home safe. 1.

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.

Why are my dash lights blowing fuses?
It also had an aftermarket radio installed in it. The problem was that the ground wire for the dash lights had been wired into the positive side of the circuit and was causing it to blow fuses as quick as you could put them in. If there’s nothing on the circuit with the dash lights I would think it should only have a 5 amp fuse.
Why does my amplifier keep blowing a fuse?
You need to look for any bare wire while insulation and trim it back so that insulation could be done properly without causing continuous blowing of stereo fuses. In other common cases, the wire to the battery is grounding that blows a fuse due to a hot connection before ruining the amplifier.
