For instance, when we turn on a car’s air conditioner that uses a relay, the current will pass through an electromagnetic coil.
Relays are electrically operated switches, commonly found in all vehicles. If the fuse ampere rating is high, the component may become damaged and fail before the fuse. Car fuse ampere rating is important when buying new fuses from the marketįor instance, if a fuse with lower ampere rating is used it will blow too soon and the connected component will not function. Placing the right fuse with the correct ampere is integral for protection. The ampere limit is usually defined on each fuse along with different colour codes. The fuses consist of a wire conductor that breaks when the current exceeds the ampere limit. The wires from the fuse box connected to the vehicle components that need protection. The fuse box is powered directly by the battery. Understanding Car Fuse BoxĪ car fuse box has a series of different fuses, relays and diodes to protect the electrical circuits from overload or short circuit. Let’s delve a bit deeper to understand how car fuse boxes work and what their types are.
Whereas the fuse box near the dashboard protects cabin components like power windows, interior lights, radio or infotainment system and turn signals. The car fuse box under the hood protects engine components including engine control unit (ECU), cooling fan, ABS motor and battery.
Car fuse box driver#
There are two fuse boxes, one located near the engine or under the hood and the other is located near the driver seat. Cars have various electrical components that require a fuse to protect against short circuits.
