On my first trip out this weekend, in the trailer I bought used this winter, my inverter wouldn't work in either of the 12v sockets. When I plugged it in and turned it on there was a slight beep, and the on light flashed slightly, then nothing. I used my plug in gauge and both sockets are only reading 7 volts. The gauge works fine and shows proper readings when I clip it into my converter/charger. I have plugged the inverter into on of the 12v sockets in my truck and it works fine. My battery set up is 2 x 6v golf cart batteries, in series, rated at 232ah and they were fully charged. Everything in the trailer that requires 12v work. Any ideas as to what can be causing this condition?
I have 2 x 12v sockets. They are both reading the same 7.05v. Because the wiring is behind the walls it's a bit hard to track and trace. I installed a new fuse panel when I installed a new smart charger module to the converted/charger and everything looks good from that end.
I don't think it's possible to draw power from a single battery. I have the negative connected to one battery and the negative to the other with another cable connecting the the other positive and negative termionals; a standard series connection. I should only be getting all the power or nothing. (as far as my limited 12v systems knowledge goes...)
I would remove and clean the ground wire from the battery to the frame. Also go under and look for any wire hooked to the frame, remove it and clean it. Odds are its a bad ground connection to the frame. Most companys use the frame to keep from running as much wire..
We spent most of our money traveling... Just wasted the rest..
Ever hear of a partially blown fuse?
I couldn't find any fuses marked for the 12v sockets so I started pulling fuses to see which circuit it was on. When I found the right fuse I looked at it closely and there was the very slightest of connections within the fuse. When I swapped out the fuse.... voila, I got full voltage in both sockets. Go figure.

I installed my INVERTERS close to the batteries as discussed in the several emails we had back and forth months back. Then you can run any length extension cords to where ever you need 120VAC power. I hate those cheap 12VDC cigarette type connectors. The more you keep plugging things into them the worse they get and finally blows a fuse for getting so hot at the connection. To me they are dangerous things to have around.
If you have a couple of spots that you always need 120VAC Inverter Power like me then hide your extension cords in WIREMOLD products from LOWES for a more permanent install of the extension cords... All I see is a multidrop receptacle mounted in the back of a cabinet top where my Home Entertainment items are located and another cabinet top where I like to have my cell phone charger, computer charger, and a couple of other must have items when camping off the power grid. Worked out good for us...

As you found out. Most all RV Electrial issues are really pretty simple fixs. If you understand how RV Electrial Systems work in the first place.
All it takes is a Multi-Meter, or a 12 Volt Tester and you can usually find any problems. Some are very easy to find, while others can be a real PITA to find. But once found, it was really an easy fix.
I haven't found anything yet, in the 45+ years as RV'ers that I haven't been able to "Fix", "Repair" or to "Replace" myself.
RV Techs will stave, before I ever need one. But on the other hand, I don't think working on RV's and doing Mods are work for me. I love to Tinker. Plus I have a very tough "Proventive Maintence Probgram" that I follow every year.
So our RV's are always in Perfect Working Condition. We are lucky, as we have a Real Stick Built, Comp Roof, Paved, Covered RV Port, with Full Hook-Ups ay home.
When we are not Traveling, I am in and out of our Motorhome almost every day doing something.
We have also done an "Inside Make-Over, on our Motorhome, to make it the way we wanted it to look and did all of the Up-Grades we wanted to do at the same time. To make it even more "Comfortable" and even more "Enjoyable".
Yep, we're finsihed, Ha Ha Ha, right !!!!. I always seem to be able to always find just one more Mod to do. You would think that after 45+ years as RV'ers, I would be tired of doing things and Mods, Nope, I love it.
