Update: Deep dive into charging system showed neither alternator was providing any current, and only one of the two AC chargers were working. And we found some things miswired, like field wire hooked to stator connection on alternator. Things were a mess. A long story, but Tiara wired the AC Chargers in parallel, each AC charger providing charge to both battery banks, so I was getting charge on both batteres with the generator running. This let me bring the boat the 650 miles from Pensacola to North Alabama. I have had the alternators rebuilt (local business said they were in bad shape) and am currently installing two Wakespeed external regulators. Also replacing the AC chargers with Pronautic 1250P chargers. Waiting on some terminals for the 3-0 wire to support an ABYC install to connect to the new shunts to measure temperature and amperage, but looking forward to the boat being correct in about a week. I suspect the batteries are damaged, and those will be checked by a battery company next week. We appear to have a voltage drop issue to the starboard engine starter, and the starter / solenoid wiring is absent from the Tiara wiring diagrams. This has been a great experience to learn the wiring on a new, for me, boat. And a great retirement hobby.
