Your car's electrical system contains many important parts. They may seem small, but they are responsible for a whole host of electrical components in your car, such as the radio, windscreen wipers, lights, as well as the car battery and starter motor. In other words, the components of the electrical system are essential. Faulty parts in the electrical system can cause problems with equipment, and your car may not even start.
Which parts belong to the electrical circuit?
Parts that belong to the car's electrical system are:
Cables & cable connectors: Used to connect the cables of electrical components to each other.
Relays: Convert control current to main current and thus send enough power to parts such as the windscreen wipers and fuel pump.
Computer (ECU): The control unit, also known as the brain of the car. The ECU reads all sensors and controls all processes such as the combustion process in the engine.
Battery terminals: Provide contact between terminal clamps and cables that supply power to the car battery.
Fuses & holders: Ensure that short circuits or damage from excessive current are prevented in all wiring in the car.
How do I know if a relay or fuse is broken?
You will often notice a defect in the fuses or relays quickly. Here are a few symptoms to look out for. If you notice any of these symptoms, check the electrical system.
- car does not start (properly)
- dimming lights (interior and/or exterior)
- Car radio cuts out
- Burning smell in the car (burning wiring)
- Battery does not charge while driving
