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).
