What's an Alternator and What Does It Do?

When your car won't start and seems to have no electric power, it's not always the battery that's to blame. It may be your alternator. Your battery simply provides enough power to start your vehicle while the alternator keeps the electricity flowing during your entire commute.

Many vehicles now have a warning light on the instrument panel that will alert you to a faulty alternator. Dim interior lights and headlights can also be a sign something is wrong. If you jump start a dead car and it starts but soon dies again, it's a good bet that the alternator is the culprit. Fortunately, these parts don't tend to go bad often or need any special maintenance.
