since you have a good VOM i would check voltage at the battery at idle, with acc's on and then off. i found that my 300e was only making 13.2 volts at idle with no acc's on. with them on it droped to 12.7, not enough to keep the battery charged, and make the car run right, as i discovered sitting on the side of the road. i may need to rebuild my alt, wich from reading previous posts is pretty easy. anyway one of the big wigs can tell you for sure. i replaced my battery with a bigger one and have not had any more problems, but my alt output is still marginal at best.
