Why is my alternator making noise?
If you hear a small rattling or grinding sound when your engine is running, this could be caused by a loose bearing in your alternator. Conversely, if you hear a constant high whine while you are driving, this is usually a sign that your alternator is failing to distribute the necessary power throughout your vehicle.
What Does a messed up alternator sound like?
The grinding sound may be caused by a worn-out bearing. Your car can also make a whining sound when the voltage regulator is sending signals to the alternator to charge more than is necessary. If you hear any type of whining or grinding sound that’s a good indication that your alternator needs to be checked.
What is the most common cause of alternator whine?

Do alternators make a clicking noise?
An alternator may make a clicking sound if the bearings or other internal components are beginning to wear. Once the alternator has been identified as the source of the sound, remove the drive belt and turn the pulley by hand. If the pulley does not turn smoothly, the alternator is worn.

What happens when the alternator fails?
