Okay... So I have a 2010 Springdale 260 SRT.I have power when plugged in but nothing from the batteries.What I've done so far.No blown fuses in electrical panel.No thrown breakers.Replaced fuse and housing on frame rail because of corrosion.Disconnected ground wire, sanded everything nice and pretty and replaced.Both batteries show over 6 Volts on my multi meter. (dual 6 volt set up)I'm headed out tomorrow night with the scouts and it would sure be nice to have power back again.Any help is greatly appreciated.Thanks,Heath

Check, clean and reseat the cable connections to the batteries - including the cable connections between your 6 volt batteries.

Do you have a battery disconnect switch that may be turned on?Did everything work before when you were not plugged in to shore power?Your 6 volt batteries would have to be hooked in series to get 12 volts. what voltage reading are you getting from both batteries connected?

This link shows a chart of voltage and state of charge for 6 volt and 12 volt batteries

No I don't have a battery disconnect.Last time I went out with it was probably February and it was working.I've been running sets of 6volt batteries since I purchased it, I understand how they work.Testing together reads 13+ volts.

Sounds like you have a fuse somewhere you have not found. There are sometimes fuses in the battery box on the pos side. Also look in the converter and pull all the fuses are re-install. On my previous trailer I would sometimes run into a problem and just pulled out the fuse and reinstalled it.

No Power unless plugged in to shore power!!! Please Help...

Also, flip off all breakers and reset same as fuses.
Since your batteries are good it sounds like the converter is ok.... but sometimes the converter may be bad which does no allow 12 volt power to get through

There may be one of those self resetting thermal circuit breakers hidden along the wires somewhere. It may have failed open...

since the batteries test ok it sounds like the converter to battery is ok. The battery should be feeding a fuse box located close to the converter. You mention that there is no 12 volt power... then the co2 and lp detector should be alarming and beeping. Maybe you have a fuse you think is ok but actually may be bad. try taking some of the fuses and move them from one slot to the other. Just have to make sure they are same size rating.

Use your multimeter to check for voltage at the 12v input to your fuse panel. If no voltage there, follow the 12v wire that comes into the fuse panel and check for 12v again, keep doing this until you find 12 volts.

You should probably check for 12v from the battery positive to ground to check the ground.

I would do it like tenbear recommends. Surefire method.
