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.
Good day!!

Hmmm, I thought I was the only one that would pull parts from one, to use on another... My 2002 4.6is has the mirror from the 2004... Now that the 2004 is on the road, I had to pull the mirror from the 2006 to use on the 2004... Fun stuff... Figured out that you don't have to do anything to get the glass off the mirror base... Just a gentle pop with a flat screwdriver... Ummmmmm, if yours is broken, buy one!!! Don't go borrowing your neighbors just cause it's easy to get them off... Ahem....

The alt output is a little low, but still in the normal range... Very low end of the normal range... Can you hook up INPA and watch it on your laptop when driving around... Demand might make the output higher... Sitting at idle might not pull that much over your 13.5V...

Cheers!!!
