Of protection for the electrical circuits in the vehicle, there is an incorporated assortment of fuses, circuit breakers and fusible links, whereas the principal fuse/relay plate is located at the engine compartment, and the interior fuse/relay plate is situated in the passenger compartment. Every fuse serves a relevant circuit and it comes with an identifier that is always placed at the fuse panel. Small, medium and large firses are used and they all have the same blade terminal arrangement; however while the medium and large fuses can be removed by finger the small ones have to be removed by pliers or a small plastic fuse puller. Whenever an electrical component fails it is always recommended that one should check the fuse first, and use a test light to probe for power on the terminal ends and if found that the fuse has been blown then one can use his or her eyes to check of the element in the fuse is melted. Besides, it is vital to replace the blown fuses with the suitable type of fuse to ensure appropriate protection of the circuit is provided. More often, if an individual replacement fuse blows as soon as it is inserted, the problem is a short circuit resulting from faulty wiring, and the problem should be looked into before applying another fuse. Also, some circuits are protected with fusible links especially for high current applications, and these once it gets a highest current it is meant to melt. While replacing a blown fusible link one should use one of the same specifications; if it blows again it is circuit trouble shooting and then fit new link.
