What happens when you remove wire from alternator?

This permits power to begin flowing through the alternator as well as the other components of the car. Always mark each wire that you remove from an old alternator, if necessary, to ensure you can easily replace the wires in the correct connectors when you install the replacement alternator.

Why does my alternator not charge my battery?

There are lots of wires in the vehicle which deliver power to the alternator. If one of these wires were to become damaged or worn out, then it could cause the alternator to fail at its job and the battery to not get charged.

Where does the second wire of the alternator go?

The second wire of the pair on Pin 2 of the alternator goes to the ignition. This permits power to begin flowing through the alternator as well as the other components of the car.

Why is there a noise coming from my alternator?

Noise from the alternator could be caused by a faulty rotor shaft, rectifiers, bearings, slip rings, stator winding or brushes. You will need to carefully inspect each of these components and replace them. One sure way of confirming that the noise is coming specifically from the alternator is to use a vacuum hose.
