Things Car Owners Should Know About Fusible Link


Many car owners visit a mechanic to get their fusible link problem fixed. Some do not even know what’s wrong with their car until a mechanic tells them that it is this tiny component known by the name of fusible link that is causing issues in their vehicle. You might have heard about traditional fuse, but you might not know what a fusible link does, how you can avoid issues in it, and how you can repair it if an issue does arise in it. The good thing is, fusible link are not that difficult to understand and repair. In this blog, we will tell you all you need to know to effectively deal with them. Let’s get started.

Role of Fuse In Automobiles

Most car owners have an idea how a fuse operates in an automobile. It is basically a small component that works as a link in a car’s electrical system. In order to protect other key components and systems from damage, the fuse is broken under certain conditions. In simple terms, when a circuit transmits too much current, a fuse burns itself out in order to prevent electrical charge’s ill effects on other components.

Difference Between Fuse And Fusible Link

If we talk about a fusible link, it is essential to understand that it is pretty much similar to a fuse; however, it is created to tackle a different type of hazardous situation. These links are basically strands of wire folded in a fireproof covering and are quite thinner than the wiring harness they are linked with. You will find them positioned in-line amid fragile harnesses and big sources of electrical current in your vehicle. The job of these links is to transfer high-current electricity but at the same time make sure that the entire electrical system stays protected from risky spikes that can very easily cause a fire. And if a surge does occur, the link protects the circuit by melting itself as its resistance to heat is rather lower.

Replacing A Damaged Fusible Link

Car owners struggle to diagnose and repair fusible link because it is not easy to find out through a visual inspection whether it is damaged or not. And since they are built to work with high-current electrical components, when they get damaged, the most common result is a no-start condition. If you own an older car, you should look for fusible link underneath the hood close to the battery or along the firewall. Look for a wire that is two gauges smaller than the harness it is linked with. You’ll know you’re touching fusible link wire because the wrapping will feel a bit rubbery and there might be ‘fusible link’ printed on it. Once you find it, you should change the length of wire with a fusible link that equals the gauge of wire required by the original design.

Problems associated with fusible links might be a bit difficult to detect, but they are fairly easy to fix.
