Regulator

After completing the DC system upgrade, we added an Ample Power
Diesel Genie.  The Genie is described in more detail on another page on this site. 
The Ample Power Smart Alternator Regulator V3 was part of the Genie purchase, and it has
been superb.  The regulator interfaces directly with our Ample Power EMON-II H1 battery monitor,
and the two work together to ensure that we have a fast, efficient battery charge. 
The dual alternator control circuitry is shown on the terminal strip to the right of the regulator.

Smart Alternator Regulator

After installing the generator and the SAR-V3 I removed the regulator from
the Amptech 125 amp alternator mounted on the Yanmar  propulsion engine.  Using the
wiring circuit shown below, the SAR-V3 now controls whichever alternator is active – the
Genie 175amp alternator or the Amptech 125amp engine alternator.
