What Is the Best Way to Troubleshoot a Faulty Alternator in an Audi 80?

I have been experiencing issues with my Audi 80's alternator and need to troubleshoot the problem. What are the best steps to take for diagnosing and resolving a faulty alternator in this specific model?

Start by checking the battery and wiring connections first. If those seem secure, then move on to checking the alternator's voltage output with a multimeter.

In my experience, it's often the voltage regulator that malfunctions in the Audi 80's alternator. Consider replacing this component if all other troubleshooting methods fail.
