Why does my electric golf cart whine?

Electric golf carts can sometimes produce a whining noise for a variety of reasons. One common cause of the whine could be a worn-out or damaged motor bearing. If the bearing becomes loose or damaged, it can create friction and result in the whining sound. Another possible reason could be a loose or misaligned drive belt. The belt may slip or rub against other components, causing the whining noise. Additionally, an issue with the controller or voltage regulator can also lead to the cart making a whining sound. It's best to consult a professional or the manufacturer to diagnose and resolve the specific reason for the whine in your electric golf cart.
