I posted a similar topic a few weeks ago though I cannot find the topic now.
1995 Sea Ray 330 DA, 4 batteries. House battery starts the Port engine.
On the hook for 2 nights this past weekend. We returned to the boat late evening the 2nd night to find a dead house battery.
From my previous post folks suggested we run the genny with the AC Converter on to keep the house battery charged. I ran the genny 4-5 times that day for about a half hour (each time) and we still had a dead house battery that night.
I ran the genny all night that night with the ac converter on, battery still dead in the morning.
Per the manual the ac converter charges the batteries. It's also my understanding the ac converter 'powers' 12 volt items when turned on versus drawing from the battery.
A dead house battery means nothing 12 volt works, not even the bilge pumps (at least not manually from the console switch).
I assume the refrig is draining the battery. We now turn it down to it's lowest setting when the genny is not running. All of the boats tied to us (much larger and diesel) kept their gennys running full time.
Other then running the genny full time, what else can we do? I can start the starboard engine, idle it for 30 minutes and the house battery is charged (charged enough for 12 volt items to start so I have to wait for the starboard engine to charge the port engine battery). My emergency start switch is not working either.
My assumption is the ac converter is not working (how does one test this?) or the genny, when runny, does not power the ac converter.
