Hey everyone, I have a few questions on my friends 89 Audi 200 Quattro T. We replaced the alternator and the battery and it still discharges the battery. Anyone have any ideas on what would make this happen? I'm not a mechanic, but i'm at a loss for what it is. Other vehicles i've worked on, changing one or the other usually solved the problem. Hopefully someone can help Us out here. Any feedback would be VERY VERY much appreciated. Thank you All.
