The battery light stays on on my car.
The alternator is in rotation but the battery doesn't 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 shortr circuit on the diode bridge.
I replace the diode bridge by a new and I refit it on the alternator.
Then I refit the alternator in the car.
