Just the Scan gauge voltage is what I am reading for the most part and I am
guessing it is the voltage at the computer. The Alt voltage is 13.9 or 14V
at its terminal (and its brand new)...Large gauge cables w/short run to the
Blue Seas combiner and to the AGM batt that done drop but maybe a 1/10th
volt.

What do you measure right at the alternator stud? My Ferd does 14.5 or
so. So did the first Ferd alternator I had.
