Alternator Charging Problem

[D]

Thanks for all the information on my problem. I placed a volt meter
on the back of my alternator last eve and after moving the variable
regulator an 1/8th turn each direciton and cleaning up some wires to
make sure corrosion was not my problem, I'm getting readings around
14 volts. However, at the batts I getting what the dash volt guage
says, about 12.3-12.5 volts. At the isolator, I am getting the same
reading at the alt/battery charger input. At the battery terminals of
the isoltor, I have the drop to the 12.5 volts. I have suspected this
thing before, but with all the other inconsistencies at the
alternator, I've never been sure. It really is multiple problems. I
think I'm geeting close and I really appreciate the input.

Thanks to all!
