What is it?
The electrical system consists of a battery, starter, alternator, and various electrical circuits.
What does it do?
The battery provides power to the starter, which is used to start the engine. The alternator then takes over and provides power to the car’s electrical systems while the engine is running. The various electrical circuits provide power to the car’s lights, horn, and other accessories. When the engine is turned off, the battery takes over again and provides power to the car’s electrical system.
Typical Wear and Tear
The most common problems are loose or corroded battery terminals, bad wiring, and frayed or damaged insulation. Over time, these problems can cause the electrical system to malfunction, resulting in symptoms such as dimming lights, slow starting, and stalling. If left unchecked, the electrical system can eventually fail completely.
- Dimming or flickering lights
- Problems starting the engine
