The electrical circuits in a vehicle are safeguarded by a combination of fuses, circuit breakers, and fusible links. Fuse and relay boxes can be found in the engine compartment and inside the vehicle, typically at the left end of the instrument panel. Each fuse is designed to protect a specific circuit, and the fuse panel cover identifies the various circuits. If the cover is missing or difficult to read, consult the owner's manual for a complete guide to all fuses and relays in both boxes. Miniaturized fuses are used in the fuse blocks, and if an electrical component fails, always check the fuse first. A test light can be used to check for power at the exposed terminal tips of each fuse. If power is present on one side but not the other, the fuse is blown. Replace blown fuses with the correct type, as fuses of different ratings are physically interchangeable but only fuses of the proper rating should be used. The amperage value of each fuse is molded into the fuse body. If a replacement fuse immediately fails, do not replace it again until the cause of the problem is isolated and corrected, which is often a short circuit in the wiring caused by a broken or deteriorated wire.

A damaged fusible link can be repaired by cutting the damaged link, stripping the insulation, twisting the exposed wire strands together, soldering the wires, and using electrical tape to cover the joint. After the repair, the negative battery cable should be connected, and the circuit should be tested for proper operation.

There are different sizes of fuses, including small, medium, and large, all with the same blade terminal design. The medium and large fuses can be removed by hand, but the small fuses require pliers or a fuse-puller tool.

A blown fuse can be identified by inspecting the broken metal element inside the glass tube.
