![]() Once located, you can replace it with a fusible link that matches the gauge of wire called for by the original design.ĭon’t try to save a few pennies by simply swapping in a thin gauge wire, as standard wire lacks the protective insulation of a proper fusible link and could lead to a short-out condition if the strands inside melt away their covering. The wrapping might feel more rubbery to the touch compared to other wires around it, and it could also have “Fusible Link” printed on it every few inches or so and sometimes tagged with “Fusible Link.” Replacing a fusible link On an older vehicle, the first place to look for these links is under the hood near the battery or along the firewall - look for a length of wire that is roughly two gauges smaller than the harness it’s connected to. When fusible links fail, they often lead to a no-start condition. ![]() This cuts off power while protecting the engine bay from a fire, thanks to its fireproof wrapping.įusible links can be frustrating to diagnose and repair because their damage can be impossible to detect with a simple visual inspection. If there’s a surge, the link actually melts, as its resistance to heat is lower than that of the circuits it’s protecting. These links must transmit high-current electricity and protect the rest of the electrical system from dangerous spikes that could cause a fire. They are placed in-line between delicate harnesses and large electrical current sources in your car-between the battery and alternator, for example. These links are actually strands of wire wrapped in a fireproof covering and are thinner (smaller gauge) than the wiring harnesses they’re connected to. Typically, a fuse burns out when a circuit attempts to transmit too much current, severing the connection before the electrical charge can have any ill effects.Ī fusible link acts much like a fuse only it’s designed to handle a different type of potentially hazardous scenario. Whats the difference between fuses and fusible links?Ī fuse serves as a link in your vehicle’s electrical system that can be broken under certain circumstances to protect various components and systems from damage.
