One common misconception people have is that their battery is supplying all of the electricity their vehicle needs. The truth is, once the car has been started, the alternator is doing all of the heavy lifting. Here are some of the things your alternator is responsible for, as well as some warning signs of problems.
In order to ensure that your battery has enough power to start your car every morning, the alternator charges it while you are driving around. When your vehicle is idling or driving around here in Anchorage, AK, it is the alternator that is powering your headlights, radio, dashboard display, and even your power steering. Comfort-enhancers like heated front seats are drawing power from the alternator as well.
If your car does not start, you may be quick to blame your battery. The alternator may actually be the problem, however, because it is not properly charging the battery while driving. The team at MINI of Anchorage also wants you to watch out for dim lights and issues with things like your radio.
