What causes a light to fuse?
The cause could be an electrical short. More often, the issue is a blown fuse or tripped circuit caused by excessive electrical current flowing through the wires. The fuse or breaker will automatically cut off the current to prevent the wires from overheating and causing a fire.
What should all fuses make test light?
If the ignition switch is ON but the engine is not running, all the fuses should read about 12V or the test light should glow. The switch to turn things on is downstream of the battery and the fuse. Tail lights should be connected around the ignition switch directly to the battery so they can be turned on without the ignition being on.

What should I do if my Fuse trip?
Put them back to the ON position. If tripping occurs again, it is probably being caused by a faulty appliance. You need to identify which circuit is affected and which appliance on that circuit is causing the problem. Which appliance is faulty? Go around the house noting which set of lights or sockets are not working.
Can a fuse be removed if there is no power?
If you use an ohmmeter, you can get false readings if there is any power in the circuit. In other words, only use an ohmmeter if there is no power on anywhere. You can remove the fuse and then check it with the ohmmeter. It depends on where the fuse is located in the circuit.

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” ).
How often do you get a blown fuse?
Most people probably have experienced a blown fuse at one time or another. Someone always knows what to do when this happens. If you’re a homeowner, that person probably is you. Blown fuses are a common occurrence.
