So I've fixed my recurring no-charge with a new alternator and external regulator. In addition, I have house batteries on an isolator (diode). The voltage drop across the isolator is about 1v -1.5v give or take. The question is, since the external voltage regulator is set to say, 14.5v in order to give my battery about 13.5v while running, and the regulator reads system voltage post-isolator, the regulator will always read a voltage deficiency and will essentially engage the alternator 100% of the time. As the alternator feeds directly into the isolator, if I were to connect the sensor wire for the regulator there, it would constantly read either residual voltage (like 0.4v) or the regulated output max of 14.5v. In short, I'm not sure where to connect this thing, or if it really matters...how frequently is the alternator engaged in a normal setup?
