How do I troubleshoot electrical issues in my Audi 80?

I've been having some issues with my Audi 80's electrical system, how do I go about troubleshooting and fixing these issues?

First, check all of the fuses in your Audi 80 to ensure they are not blown. If they are, replace them with new ones. Then, check the connections for the battery and alternator to make sure they are clean and secure. If those are fine, you may need to take your car to a mechanic to have the electrical system diagnosed and repaired.

If your Audi 80 is experiencing electrical issues, it could be a sign of a failing battery. I recommend checking the battery's voltage with a multimeter, if it is below 12.6 volts, it may be time to replace it. Additionally, be sure to check all of the electrical connections and clean them if necessary.
