Alternators

Alternators are devices used in today's vehicles to charge the battery and power the entire electrical setup when the engine is running. This component works with the battery and voltage regulator to provide power for the electrical parts of a car such as the interior and exterior lights and the instrument panel. The battery in your vehicle does not have enough capacity to stay charged and power other parts of the car all day. In fact, the majority of electrical systems in your BMW such as the lights, power windows, stereo, speakers, and infotainment systems draw their electrical power from the alternator. Therefore, when such components fail, then the alternator could be the key culprit as opposed to your battery. Since it also charges the car battery, a dead battery or one that's not charging is a common symptom of a faulty alternator. It's important that you get both parts checked out to verify where the problem lies.
