How can I effectively troubleshoot the electrical system on an Audi 80?

I have been experiencing some issues with the electrical system on my Audi 80 and I'm not sure where to start in terms of troubleshooting and fixing the problem. The car is not starting consistently and there are some strange electrical glitches happening. Any advice on how to tackle this issue?

First, check the battery and alternator to make sure they are functioning properly. If those seem fine, then your next step should be to inspect the wiring and connections for any signs of damage or corrosion. If you are not comfortable doing this yourself, it is best to take the car to a trusted mechanic.
