OK. Here we are, presumably in the right forum since that's where I was moved to. I'll answer some of your questions now.
The trailer is an Alpenlite, St. Andrews 33,built in 1995. I bought it from my sister in about 2000 and have lived in it ever since. My problem with the 12 volt is that it ALL stopped working a few days ago probably because I let the batteries go completly dry. They were new when I bought the trailer so they are way past replacing anyway so yes I will be getting a couple new batts as soon as I win the lotto here in Florida. They aint cheap and I'm living (existing) on social security only.
I know about the fuses on the breaker panel and they are all ok.
I can't get to the converter because it's in the storage area under the bow and full of junk that I need to go through and get rid of.
I do know the original converter was a Todd 45 amp but this trailer got zapped by lightening just before I bought it so the converter was replaced with a 55 amp but I can't see the manufacturer. Can't see if it has any fuses either.
The 110 breakers are all ok.
I don't see one just for the converter.
So filled the batts up with water just to see what happens and that's nothing. I get a reading of 1.7 off my meter at the 12 volt fuse panel so that's all I'm getting. Question is,since the 12 volt wires are all tied directly to the battery cables which are tied directly to the converter, wouldn't I get 12 volts at the fuse if the converter was working?
I'm thinking that the dried out batts shorted out the converter and stopped the whole shebang in it's tracks.
As for Bonita Springs it's on the West Coast of Florida about half way between Naples and FT. Myers off I-75. I-95 is on the East Coast so you have to come across I-4 at Tampa/Orlando or across Alligator Alley to get here. Don't get out of your car on the Alley either. There really are alligators out there,no kiddin'. Pete
