How to Troubleshoot Generator Abnormal Noise

The abnormal sound of the car's alternator may be caused by too tight or too loose the rotating belt of the car's alternator, or it may be that the bearing of the car is damaged or lacks lubricating oil, causing the stator and rotor to collide, or the brushes may be too worn .

Automobile generators can be divided into DC generators and AC generators. Since the performance of AC generators is higher than that of DC generators in all aspects, DC generators have been eliminated at present. The current route is from the positive pole of the battery to the charging indicator light, through the adjustment contact point, etc., and finally reaches the negative pole of the battery. According to different classification methods, alternators can be divided into ordinary alternators, integral alternators and other alternators. The integral alternator supplies current to the battery when the switch is closed.
