Glass fuses have a low breaking capacity. It's easy to see when they're blown: the glass will be discolored and the filament broken. Replace yours today!

Same day shipment. Product experts available. Customers rate us: 4. A fuse is an electrical device that breaks a circuit under conditions of short circuits or current surges. The fuse contains a metal filament that burns when the fuse blows during a current overload.

If you think a fuse in your car has blown, you should use a multimeter to check it before you replace it. This will help you figure out if the fuse is blown or if the electrical circuit has another problem. Fuses are made to protect electrical circuits from damage that could happen when too much current flows through them. When a fuse blows, it stops the flow of electricity so that the extra current can't damage the circuit. Fuses come in different sizes and amperages, and the right one is chosen based on how much current the circuit is designed to handle. The size of the fuse also affects how much current can flow through it before it blows. 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. Over time, fuses can become corroded or blown, and this can lead to all sorts of electrical problems. Fortunately, testing a fuse is easy to do with a multimeter. By testing your fuses regularly, you can head off potential problems before they become serious. So don't neglect this important task - test your fuses today! If your car has blown a fuse, it's important to replace it as soon as possible. A blown fuse can cause all sorts of electrical problems, and can be a real pain to deal with.

Electrical circuits are peculiar in the sense that its the smallest components within them that play the biggest roles. The fuse is one of these small components, serving as a self-sacrifice that prevents unexpected power surges from rendering the entire circuit useless. Is a device within your home or car not receiving power? Do you suspect that the problem is from the fuse box? Fuses are simple components designed to protect electrical circuits from power surges or overloads.

We will get into the detail on how we will test the fuses shortly. But, before we get into that please read the table of contents below. However it is worth noting and understanding the different kinds of fuses, how they work and what typically cause them to fail. This understanding will help you in keeping your fuses healthy, and better equip you to test them effectively with a multimeter to diagnose any faults. There are so many different types, so I will touch on the most popular you will come across when testing with a multimeter. These types of fuses are typical in standard electrical circuit fuse boards. There are primarily two types that are used. What is interesting about these types of fuses is that they are correlated with a specific type of socket. The rejection base type fuse The Type S can only work with a socket of the similar current rating as the fuse.

Skip to Content. A fuse contains a metal element designed to carry only a limited electrical current. Testing fuses can be done using a multimeter, and doing so is both fast and easy to learn. Not Helpful 23 Helpful Home How-To. Fuses are really just wires that are designed not to last, but their purpose is to prevent damage to more valuable electrical equipment or prevent fires especially in homes caused by power surges. A good fuse has a connector that connects from one end of the fuse to another, as seen in Figure 2 left and Figure 3. Make sure to get a fuse that is rated for the same amperage as the one that blew. Please log in with your username or email to continue. Thanks a lot. Support wikiHow Yes No. Blade fuses plug conveniently into banks, and relatively little space is required to house a large number of them together. Your multimeter should read very close to 0. We're glad this was helpful. Simply set your multimeter to the correct settings, place the probes on the correct terminals, and observe the reading.

Before you test a fuse with a multimeter, turn off the equipment and remove the fuse by pulling it straight out of its slot. Close up the fuse box. If you think a fuse in your car has blown, you should use a multimeter to check it before you replace it. A blown fuse indicates that there is an overload somewhere in the electrical system.
