Alternator

The alternator keeps the battery in a constant state of charge anytime the engine is running. If your lights are dimming or you hear excessive bearing noise around the alternator, chances are that it's time for a replacement.

If you are having issues with voltage peaking, lights fading in and out as your driving, or your battery keeps dying despite the car running, It could be the result of a faulty voltage regulator. Voltage regulators control the amount of power coming from the alternator.
