 How does an ALTERNATOR work? How to test each component with a multimeter and how to repair it ?

The battery light stays on on my car.

The alternator is in rotation but the battery does not charge.

After checking that the issue doesn't come from the car, I test the alternator on the table.

I test it with a drill and observe that it doesn't work.

Before to open the alternator, I explain briefly the role of the

stator and the rotor.

I show you the schematics of the components of the alternator:

The stator, the rotor, the regulator and the diode bridge.

I test the rotor with a multimeter

I test the regulator, this doesn't work.

I test the stator and the diode bridge together and separatly.

I notice that a diode is in short circuit on the diode bridge.

I replace the diode bridge with a new one and I refit it on the alternator.

Then I refit the alternator in the car.

An easy to follow, step by step guide to alternator testing & repair. How to properly test, troubleshoot, repair alternator vehicle charging system rectifier diodes, stator and rotor (field) windings, brushes, bearings, and voltage regulator using a digital multimeter in this video. You'll learn exactly how a car alternator (generator) works. Enjoy!
