To fix a noisy alternator, first inspect the belt for wear and tension. A loose or worn-out belt is a common cause of noise. Next, check the alternator bearings; if they are worn, they might need replacing. Also, ensure the pulleys are aligned properly. If these steps don’t solve the issue, have a professional mechanic inspect the alternator, as internal components like the rectifier or brushes might need attention.
