I had this problem in one of my cars..alt looked new...changed voltage reg..etc etc.
Took the alt in and had it checked, everything ok. I ended up swapping in another alt and it was fine.
I tried the one I took out in another car and it was showing over 18v....so it was the alt after all even after the rebuilders said it was fine.
