New to our 2000 380 AC, having her for just five weeks. Went to the Islands Saturday and Sunday about half way through the day we lost all 12 volt power on the Starbord side of the boat. On inspection of the AC converter there the power light on the unit was off. Checked all the breakers in the 120v and 12 v panel and the were all fine. The Port batterys had a charge so we started the motor and then using the emergency switch started the starboard engine and recharged batteries and the lights came on. HELP is there another mystery GFI or breaker I'm missing?

Genny will run battery charger, sounds like you just drained the house battery.
 
Where you hooked up to shore power at the islands when you lost 12v power? Where you on shore power when the converter light was off.
 
Yep, another boat with the house wired to the engines. Factory sure to go cheap and combine everything
Have a good electrician move everything from the engine battery to the house battery. Just think, if the other battery was down on power you would be SOL right about now with 2 dead engines, a dead generator battery and no light or radio.
An operating manual would be a good idea too.

The boat was fine in the morning, disconnected shore power as usual. Went out for the day and then reconnected to shore power on return. We ran the Air conditioner that night and the next day. About mid day I noticed the stereo was acting up and then it quit working. Thats when I realized the lights in the main cabin wouldn't work, so I reased the hacth to look at the AC Inverter and saw there was no aparent power to it. I think it has just died, but the owner of the marina thinks there is a breaker off somewhere.
 
Is there a breaker marked converter on the main panel. The converter is the battery charger. If that breaker is turned off, your batteries won't charge and the power you had the day after the mishap was possibly from the engine alternators charging the batteries on the run.

Pix would help.
 
The 380 has 5 group 29 batteries, one of which is dedicated to start the generator. This could be a number of things. Could be a power pedestal breaker, but there are also breakers inside the transom where the power cords plug in. Additionally, there is a breaker on the main panel for the "Converter" aka the battery charger. Also there are GFIs inside the boat,; one for each side. The port GFI is in the head, and the Starboard GFI is in a storage cabinet in the aft cabin. Feel free to post any other questions o the 380tead. Good luck.

Just re-read the post, and saw the subject boat is an Aft Cabin....I was thinking it was a Sundancer. My apologies. Probably a lot of these thing do apply, though.

Didn't post exactly right but if your using 3000 watts AC ,your DC input current is 150 Amps. No wonder the batteries got drained.Learn to run the gen for the heavy AC loads when running the boat.
 
Turns out it was a bad battery charger, replaced today by Marine Max. They had to send the tall skinny guy to fit in the space.
