Troubleshooting

Alternator not charging the battery

Whining or squealing noise from the alternator area

This could indicate a worn or improperly tensioned drive belt, or a failing bearing within the alternator. Inspect the belt first. If the belt is in good condition, the alternator may need replacement.
