I've already posted this in tech, but another one can't hurt. 89 Audi 200 Quattro turbo. New Alt. and a new battery, new wire from alt to batt, Wire from alt to starter, and new ground wire. I'm no mechanic but wouldn't you think replacing both would solve the problem? wrong. the car still discharges the battery when driving. it seems to keep volts at idle. fully charged battery, about 10 miles of drivin gand the battery is dead. Any ideas? Any feedback wouls be GREATLY appreciated. Thank you All.
