Then the alternating current (AC) is transformed into a direct current (DC) that charges the battery. Some of the things to look for are no starting and trouble starting, dimming lights and problems with stereo system output. If your car starts but stalls when you're underway, your battery is probably not being recharged due to a faulty alternator.
