Symptoms of Alternator Bearing Problems

by MayankJ

The alternator in a vehicle takes gas and converts it into power that the vehicle can use. According to Mister Fix It, the alternator is vital to keeping a vehicle's electrical system running at optimal performance. When the alternator bearings on a vehicle are not working properly, the alternator does not turn properly and thus the alternator does not work.The alternator bearings turn the alternator so it can convert power from gas to electricity for systems like the air conditioner, radio and headlights. The symptoms will show different problems with the alternator bearings and other issues in the vehicle. Once the symptoms are identified and the problem is known as an alternator problem, fixing it is possible.

Progressive Squealing Sound

A progressive squealing sound, or a sound that gets louder and makes a squealing noise, is a sign of alternator bearing problems. Usually, the bearing is loose when this occurs. The mechanic should rule out other potential problems that come with similar symptoms, such as timing belt problems. Once it is determined that the alternator bearing is loose, replace it because a loose bearing gets damaged.

Dim Lights

Alternator problems cause dim lights. If the alternator bearings are not properly turning the alternator, the lights will not work properly because they are only getting power from the battery and not from the gas. Dim lights alone, without other symptoms, are usually caused by dirt or old bulbs, but if other explanations are eliminated, the alternator is a potential cause.

Car Lights Come On

Alternator problems or issues with the alternator bearing cause the warning lights to turn on. The "Batt" or "Gen" lights are the most common lights that come on when there is a problem with the alternator. These do not always come on, especially if the battery has plenty of charge, but when these lights come on there is a good chance the alternator or alternator bearing is the problem.
