The three wire system makes enough voltage to get 14.5* at the battery, which I why I like them. They sense the battery voltage, and make as much as needed to get it right, inspite of old wiring and terminals. So 16.5 at the alt may be reasonable. (Where did you check? Do again at batt?)

Perhaps the 1-wire conversion makes 16.5 to guess at worjing losses? No need to change yours?

*Alt voltage got bumped up a bit lately, from 14.5 to umm 15.2? So a new reg would make all my points more likely to line up with your alt.
