How to replace the alternator in an Audi 80 car?

I am experiencing issues with my Audi 80's alternator and need to replace it. Can you provide a step-by-step guide on how to do this?

First, disconnect the negative terminal of the battery to prevent any electric shock. Then, locate the alternator and loosen the tensioner and pivot bolts to remove the belt and pulley. Disconnect the wires and mounting bolts, and remove the old alternator. Finally, install the new alternator in reverse order of removal.

Make sure to use a digital multimeter to test the voltage and continuity of the alternator before removing it. This will help determine if the issue is indeed with the alternator and not a different component.
