A combination of fuses, circuit breakers and fusible links protects the vehicle's electrical circuits. There are two fuse boxes: one in the engine compartment and the other in the passenger compartment. The engine compartment fuse box is positioned at the left side of the engine compartment whereas the passenger compartment fuse box is located at the left end of the instrument panel. Every fuse has a specific purpose and included inside the fuse box cover is a spare fuses as well as removal tool. These use miniaturized blade terminal design for easy replacement or removal from a circuit. Using a test light, power can be checked at exposed terminal tips to ascertain if it's present on one side but missing on another side meaning that it's blown out completely. By simply plugging out an old fuse and inserting with new of same type together with amperage rating will be best way to go when replacing blown ones because they do not require any additional technical steps apart from just exactly doing what their names imply. Fusible links are employed where there may not be any need for ordinary fusing, or where high currents flow through them; therefore, these kinds of linkages can be substituted by obtaining another piece having similar amps. Circuit breakers usually protect certain circuits and are mostly located under an instrument panel. They reset automatically; however, if a circuit does not turn back on again after resetting it should be checked immediately. When checking a circuit breaker one must pull it slightly up so as to probe with voltmeter while each end should have battery voltage whereby only having voltage at one end means that such circuit breaker ought to be changed therefore providing evidence supporting this test result. Manual resetting applies in some cases to certain types of these devices.
