Fuses, fuse links, and circuit breakers protect your vehicle’s electrical system from overloading. If electrical parts in your vehicle are not working, the system may have been overloaded causing a blown fuse or tripped circuit breaker. Here you will find various information related to automotive fuses – the location of units, fuse box diagrams, fuse layouts, and assignment of the fusible links, circuit breakers, fuses, and relays.

Why do fuses burn out?

They burn out due to exceeding the permitted load in the electrical circuit. This may be due to the connection of additional equipment, short circuits, wear and tear or jamming of motors, and other causes.

How to check the fuse?

The easiest method is to visually inspect the fuse – if the fusible element inside the fuse is damaged, the fuse has blown.

Good and blown fuses

You can also check it with a multimeter. In “continuity mode”, it will emit a sound signal when the probes touch both of the fuse’s contact points if the fuse is good.

Circuit Breakers

The circuit breakers will reset themselves and allow the electrical parts to work again once the overload on the circuit is removed. If the circuit breakers continue to cut off electricity,
have your vehicle’s electrical system checked.

Relays

Relays are devices that receive signals from components or systems. After receiving signals, relays transfer these signals to activate or deactivate other components or systems.
