When the alternator is not working properly, it does not provide enough electrical current to power the car's electrical system. This can cause the battery to discharge, which can lead to a parasitic draw. In addition, a bad alternator can also damage the car's electrical components.
Parasitic draw is a condition in which a car's battery is drained by one or more electrical components that continue to draw power even when the car is turned off. This can be caused by a variety of factors, including a faulty alternator, a faulty ignition switch, a faulty door switch, or a faulty radio.
