The protection of the electrical circuit is provided by fuses, circuit breakers, and fusible links Most of the fuses and relays are mounted in the engine compartment on the main fuse/relay panel while others are located inside the passenger compartment on the interior fuse/relay panel. Every fuse is designed to guard a unique circuit; nevertheless, various sizes including small, medium, and large are usually used, but the blade terminal is constant. Whereas medium and large fuses can be pulled out physically, small fuses have to be pulled out a tool like a pair of plier or a plastic fuse pulling tool. Whenever you have an electrical component that is not working, the fuse should be checked by using a test light on the terminal tips; if one side has power only the fuse is blown and this is easily determined since the element between the terminals is melted. Blown fuses should be replaced with the right types and should not be replaced with fuses of different ratings even if they are physically compatible with the slot; every circuit needs a certain measure of protection provided by the amperage value inscribed on the neck of the fuse. A new fuse that blinks should then not be replaced again until the real problem that commonly is a short circuit as a result of faulty wiring is fixed. Also used are large, high amperage fuses utilized in the place of fusible links which are located in the under-hood fuse/relay block.

When replacing a blown fusible link, it is important to use one of the same specification, and if it blows again, troubleshooting the circuit is necessary before installing a new link.

Each fuse is designated for a specific circuit and is identifiable on the fuse panel.

Fusible links are used in circuits that are not typically fused, such as the alternator circuit. On some vehicles, the alternator circuit runs from the battery to the underhood fuse box and then to an inline 200 amp fusible link.

Disconnect the cable from the negative terminal of the battery, cut the damaged link out, and solder a new one in its place. Cover the exposed wires with shrink-wrap tubing or plenty of electrical tape.

It is important to replace blown fuses with the correct type because fuses of different ratings are physically interchangeable but should match the specified rating to ensure proper protection for each electrical circuit.

A blown fuse can be identified if power is present on one side but not the other, or through visual inspection, as the element between the terminals melts when it blows.
