Thanks for the help, Andy. There have been so many problems, I have lost track.... but I do recall seeing alternator output voltage going off the charts (over 18v and climbing with rpm). Question is, what would cause that? I can check it again to see if that's still happening. Not sure what to check on the regulator.

We went through 3 new regulators, none of them worked. When you say you'd get a newer one, do you mean convert to internally regulated? I asked my mechanic if that would fix the problem and he said "maybe".
