Of all the electrical parts in your vehicle, the starter, alternator and battery may be the most important. Located at the rear of the engine or at the front of the transmission, the starter (as evident by its name) starts the engine when the ignition switch is turned on. The component that charges the vehicle is the alternator. It does so by generating direct current to charge the battery, while at the same time powering the electrical system while the car is running. Finally, supplying power to the starter and the ignition system is the battery. By working in tandem with one another, these components help to power other electrical parts in the vehicle such as power windows, headlights and all other lights, meters, windshield wipers, and their respective switches.

Problems with any of these functions could indicate an issue with the component itself, such as the headlight assembly, or perhaps, it could be caused by an issue with the power source like the battery or alternator. We recommend getting a diagnosis from a trusted professional to determine what electrical parts need to be swapped out.
