Fusible Links


A fusible link is a protective device used in an electrical circuit that acts very much like a standard fuse. The major difference is that fusible links are larger and capable of conducting a higher amperage than most fuses. When the current increases beyond the rated amperage for a given link, the fusible metal of the wire link will melt, thus breaking the electrical circuit and preventing further damage to any other components or wiring. Whenever a fusible link is melted because of a short circuit, correct the cause before installing a new one. There are four different gauge sizes commonly used and they are usually color coded so that they may be easily installed in their original positions. Fusible links are located all over your vehicle and the wiring diagrams should be consulted.
