Blown fuses: This is the most common problem that can occur with fuses.The multimeter should read 0 ohms if the fuse is good, or infinity if the fuse is bad.Ĭommon problems that can occur with fuses.Turn on the multimeter and set it to Ohms mode.Connect the other lead of the multimeter to the metal tab on the side of the fuse box.Connect one lead of the multimeter to the exposed wire on the fuse.If there is exposed wire, the fuse is bad and needs to be replaced. If there is no exposed wire, the fuse is good. So don't neglect this important task - test your fuses today! HOW TO TEST A FUSE OF A CAR WITH A MULTIMETER? By testing your fuses regularly, you can head off potential problems before they become serious. Over time, fuses can become corroded or blown, and this can lead to all sorts of electrical problems.įortunately, testing a fuse is easy to do with a multimeter. If you notice that your car's electrical system isn't working as it should, one of the first things you should check is the fuse box. Why it's important to test your fuses regularly? The size of the fuse also affects how much current can flow through it before it blows. When a fuse blows, it stops the flow of electricity so that the extra current can't damage the circuit.įuses come in different sizes and amperages, and the right one is chosen based on how much current the circuit is designed to handle. Fuses are made to protect electrical circuits from damage that could happen when too much current flows through them. This will help you figure out if the fuse is blown or if the electrical circuit has another problem. If you think a fuse in your car has blown, you should use a multimeterto check it before you replace it.
