camper not charging the battery?

I have a 2010 rockwood highwall 277 popup, we bought it new and are on our 5th season with it. Battery is two years old. I usually leave the pup plugged in on shore power at home and we always camp with electric hookups.

last month, we were at a campground and the campground lost power. camper lost all power, there was nothing - not even the ceiling lights that should have run off the battery (?). the fridge would not work at all either. when the power came back, everything worked. So I figured I had a bad battery. Took battery in to an auto place to have checked, was dead but they charged it up and said it was good. I had it in the house and picked up a battery charger/tender. after a week of just sitting in the house, hooked the battery to the charger and it gave a reading of 12.7 volts and started recharging. talked to the auto guys and they replaced the battery as it should have remained at full charge. k, installed new battery and off I go on a camping trip thinking (hoping) I have fixed the problem. We camp all weekend and have no issues, everything works. Go to leave at the end of the weekend, unhook from shore power and yep, dead battery (fridge went dark and CO detector starts wailing) all is fine once I hook up the tv and start the engine.

I have checked all the fuses and they seem to be fine. I do not have a cut off switch installed on the battery - I usually pull the 30 amp battery fuse to stop the parasitic drains on the battery. I crawled under the pup looking for little boxes or switches, there is nothing in line other than the 30 amp battery fuse.

what can the problem be? as the converter seems to be working, why is the battery not charging? (it is a WFCO converter btw).

With your camper hooked up to shore power........you need to take a DC voltage check on your battery. It should show something like 13.8-14.4 VDC......if not, your power center is not charging your battery.........it may be providing DC voltage.......just not enough to charge your battery.

There are two current limiters that have a circuit breaker on one short side.

One is very close to the battery and one is close to the metal umbilical cord.

One or both have opened. Feel the short sides of each and push the popped button back in. It should stay and you are back in business.

Also check to make sure the white ground wire bolted to the frame is not rusted or corroded at the threads of the screw.

This is just to determine whether it is charging or not...........Herk has some addition things to check which can very well be the cause.

Look close to where your umbilical goes into the metal box.
That is one. The other may be inside the camper (near the battery) or under the frame (I am told).

Thanks, I was thinking it was a switch but as I have not found it, it seems to well hidden. Will look some more this weekend when I have it at my dads and he can help me find it.

Nope, nada, zippo. There be no switch like your pictures. We looked all over, (me, my hubby, and my dad). The only thing we see is the 30 amp fuse holder near the battery which I now suspect to be the issue. The fuse is good, but as soon as I unplugged from shore power, the fridge (running on dc at the time as we were getting ready to tow) went dark and I know the battery had full charge as I used a battery charger on it. When I jiggled that fuse, the fridge came back but did not stay on. So will be replacing that fuse holder and see if that solves the problem.
