When an electrical circuit in a car fails, the most likely reason is a blown fuse. The owner's manual will contain a diagram of the different fuses, each circuit identified. Identifying the possible fuse, from the manual, and then looking at the fuses physically, will most likely show which fuse is involved. There is also likely, a fuse diagram within the fuse box showing where each fuse is. The fuse needs to be visually inspected. Good fuses will show a shiny metal link on top. Blown fuses will show a dark gap. Sometimes, you need to pull the fuse out of the socket and look at it through the light. You can then see the broken link clearly. Another method of finding blown fuses is by using a volt meter. Normally, the voltage across a fuse is trivial, but when a fuse has blown, the voltage across it will be around 13 volts. This is because the circuit has been broken and the full battery voltage is across it. For a tail light, the lights need to be turned on when checking the voltage across the fuse.

How can you tell if a fuse is blown?
There are many ways to tell if a fuse is blown. The most obvious way of telling is if it doesn't work.
How can someone tell if an ac relay fuse is blown?
A relay does not have a fuse. The circuit for the particular relay is fused. You can tell if the fuse is blown by testing it with an ohm meter.
How do you tell if an automotive fuse is blown under the hood?
Use a test light, Hook up a test light to the ground post of the battery and check both sides of the fuse. If the light lights up on one side but not the other side the fuse is more than likely blown. If the test light lights up on both sides the fuse is good.
Would a blown brake light fuse on 03 Saturn L200 cause gear shift to malfunction. How do you change fuse for brake lights on 03 Saturn?
Yes, a blown brake light fuse causes the shift interlock to malfunction. If the interlock can't tell if the brake is depressed or not, it won't shift out of park. The brake light fuse is a 15A in the engine bay fuse box.
Which fuse in an 88 Cutlass Supreme controls the dome light and cigarette lighter?
Accessory Fuse. If you have a manual, it'll tell you exactly which access. fuse it is if you have more than one, otherwise, resort to the old pull and look method. In case you don't know how to tell if the fuse is blown, there's a metal arch in the fuse, and if the arch isn't complete, the fuse is blown.

Pull the fuse out and have a look at it and if the wire inside is broken then its blown
How can you tell if a fuse is blown to the fuel pump?
Remove the fuse and check it with an ohm meter.
