Where is the fusible link located?

They are placed in-line between delicate harnesses and large sources of electrical current in your car—between the battery and alternator, for example. These links must transmit high-current electricity, but also protect the rest of the electrical system from dangerous spikes that could cause a fire.

Can a fusible link be reset?

Fuses, fusible links, and circuit breakers protect an electrical circuit from damage caused by overload or short circuit. Fuses and fusible links operate once and then have to be replaced; a circuit breaker can be reset (either manually or automatically) to resume normal operation.

What do fusible links look like?

What fuse controls the alternator?

Do I need a fusible link between alternator and battery?

Fusible link in the alternator charge wire would protect against a dead short in the alternator. Unusual, but it could happen. These links protect the car from the battery current. They are designed to go open in response to a dead short, without setting the rest of the car on fire or melting the harness.
