When the alternator is working properly, it generates electricity to power the electrical components of the vehicle, such as the lights, radio, and air conditioner. It also charges the battery, which provides backup power when the engine is not running.
If the alternator fails, it will no longer generate electricity to power these components. As a result, the battery will begin to discharge, and eventually, the car will lose power and stall. This can happen while you are driving, or it can happen when you try to start the car.
If the alternator is only partially functioning, it may still be able to generate some electricity, but not enough to power all of the vehicle's electrical components. This can cause the battery to discharge more quickly, and eventually, the car will still lose power and stall.
In addition to causing the car to lose power, a faulty alternator can also damage the battery. When the alternator is not working properly, it can cause the battery to overcharge, which can damage the battery's cells and shorten its lifespan.
If you suspect that your alternator may be going out, you should have it tested as soon as possible. Replacing a faulty alternator is a relatively inexpensive repair, and it can prevent more serious problems, such as a dead battery or engine damage.
