How to Check the Status of a Fuse

Model: (Various brands) Various
Part: Fuse box

Video tutorial

Today, we will see how to check the status of a car fuse. Inside the vehicle, there are usually two fuse boxes, located in the cabin and under the bonnet.

The fuse is a protection that breaks when there is an electrical problem; the most common causes are: overload, short circuit, or a faulty component. To check the operation of a fuse, you can use a fuse tester.

Place the ground clamp on the bodywork or the negative terminal of the battery and touch the fuse with the two small metal points. If it lights up on both sides, the fuse is OK; if it lights up only on one side, the fuse is blown.

If it does not light up on either side, there is no power in the circuit, but in these cases, it does not necessarily mean that the fuse is the problem.
