Almost all electrical circuits employed in the operation of the vehicle are protected by fuses, circuit breakers as well as fusible linkages; the main fuse relay is situated in the engine bonnet on the driver's side in front of the battery, and the interior fuse/relay is positioned within the passenger compartment to the left and below the steering column. Different types of fuses are small fuses, medium fuses, and large fuses that are installed in the fuse blocks whereby the small fuses demand a tool and commonly known as fuses pullers made up of pliers or a mini plastic fuse puller. After an electrical component is problematic, one has to observe the fuse first since the element between the terminals which melts whenever a fuse is blown can be easily spotted; the existence of power at the exposed terminal ends is confirmed by using a test light. Faculty from a different rating with the blown fuse jeopardizes circuit protection, so it is vital to use the correct kind of fuse. If a replacement fuse blinks out as soon as it has been placed, then the problem that prompted the blown fuse, common one being a short circuit, should be fixed before another replacement is made. Some of the circuits also have fusible links and these areas include high current areas which can be replaced with links of the same amperes after removing the negative cable of the battery. Circuit breakers guard individual circuits like the power windows or the heated seats, that automatically pop and reset when there is an overload; if it does not, it requires immediate check. A simple form of test is when the CB is slightly withdrawn from the socket, one may probe with a voltmeter to check if battery voltage is available at both ends; often if it is not, then replacement is necessary and some types of circuit breakers may have to be reset physically.

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.

Some circuits are protected by fusible links, particularly those that are not typically fused or that carry high current, such as the connection between the alternator and starter motor.

It is crucial to replace blown fuses with the correct type, as using a fuse with an incorrect rating can compromise circuit protection.

Each fuse is designed to protect a specific circuit, which is identified on the fuse panel. Various sizes of fuses are used, including small, medium, and large, all featuring the same blade terminal design.

Small fuses require pliers or a plastic fuse-puller tool to be removed.

Various sizes of fuses, including small, medium, and large, are utilized in the fuse blocks.
