We are sorry but we cannot give specific recommendations regarding which fusible link wire to use other than to go with the OEM spec.Ĭan a blown fusible link be replaced with a MAXI fuse? But proceed with caution as fuses/breakers are not necessarily a direct replacement for fusible links, and could lead to damage to the vehicle, including a fire.

Generally people go with a fuse or breaker rated at about 10% greater than the output of the alternator. Although we don’t necessarily recommend this course of action, another option is to use a Maxi Fuse or Breaker in place of the fusible link wire. If your application is not stock, you can do some more research to see if you can determine the appropriate fusible link wire to use. However it is important to determine what caused the original one to fail so you don’t burn it out again. If your application is otherwise stock, it is best to directly replace your fusible link wire with one of the same specifications. There is some specific engineering that goes into determining what gauge and length of fusible link wire is used. The automotive service industry recommends using the same gauge and length as the blown fusible link after the cause of failure is corrected.

What size replacement fusible link should be used? In an extreme current overload situation, the conductor within the link is melted while the ensuing flame and spark is contained within the link's insulation.įusible links are not rated in amps like fuses because each installation is unique and designed to meet specific circuit protection requirements. Below are some that we get most frequently.Ī fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness that is designed to protect the harness in applications where a fuse is unsuitable. We get many questions about fusible link wire.
