Bought this back in August. I didn't plan on it having a bad alternator, but it did. So I yanked the reman'd one that had 2,000 miles on it out of my e39 and put it into the x5. Since I parked my e39 for the winter, I figured I'd just buy another alternator for it later.

Drove the x5 for a few months, but parked it in December for some rear suspension work. Got it finished up recently and checked the voltage and it's charging quite low. It seems to charge constantly around 12.8 - 13.0. But it can vary anywhere from 12.4 to 13.5. Had the battery tested and that checked out good. Does it seem like my 2,000 mile alternator is dead? That's what I'm fearing, but just want to see what others have for ideas.
