I have a 2011 roo 23ss. We just went camping last weekend for the first time this year and everything was working great.I have a kill switch for my battery, so after hooking up the truck, I turned the switch on so the battery could get a charge on the way out. I hooked up shore power and left switch on. we stayed for three days. When tearing down I unhooked shore power and ran slide in on the battery and it worked fine. Left switch on for the ride home but when we got home and unhooked power from truck, the trailer had no power. I checked water level in battery and its good. I put a charger on it for about 1 hour and then turned it off. tested lights in trailer and they came on. What would run my battery down so low? would running the slide in on just battery cause it?

Sounds like a suspect to me. I always leave 110 to the rig until I am ready to pull out. Guess I like it cool inside while I am getting ready to leave.

rebel412,
I doubt moving the slide once (or a dozen times) would deplete a fully charged battery.
I would look for some other load being on or suspect your batteries (though it seems unlikely since your rig is so new) and or charging system.
You might want to put your charger on overnight and then test the battery charge with a hydrometer to see how charged it really is.
Hope this helps and good luck,
Steve

Thanks for the replies. I will leave it charging overnite and test in the morning. I hope its just the battery. Easy fix.

Are you sure fuse on TV is in place so battery gets charged while towing? Might be worth checking.

if you expect your tow vehicle to fully recharge a depleted battery, in just a few hours, you're sadly mistaken.
only if you have your tow vehicle specially setup to provide a large amount of alternator current, the most you can expect is a trickle charge.
it would take over 12 hours of driving for most tow vehicles to fully recharge a depleted battery.

Guessing from the data provided:
The battery was not charged when the weekend started and (as noted above) the tow vehicle really won't charge it in a short length of time. Does your battery disconnect sever the Negative (Ground) connection? The White wire? If not it's not completely disconnecting the battery unless you have a myriad of wires connected to the cutoff switch. The White wire connected to the battery Negative pole?
The second part, though, is interesting as the converter (inside the power center) should have more than charged the battery in two days -- if it was connected to the trailer battery. The fact that the trailer battery would power the lights after a short charge though indicates the connection is good.
A quick suspect is the break-away connection for the trailer brakes. If this was somehow pulled it should lock the trailer brakes but quickly kills the battery. I could pull my popup with the brakes at full powere as they never locked locked but I could really feel it. My hybrid brakes lock. Still something to check.

My guess: Battery was always dead, and never connected to the converter/charger. When the truck is connected, the truck battery supplies power to the camper. When plugged into shore power, the converter can provide enough power to operate the slide.
Pull the fuse inside the camper battery box. Check it. If it looks good, keep the fuse out. Plug in the camper and check for voltage between negative and the camper side of the fuse holder. You should see ~14v. Report back your findings.
Good luck.

Oh, and depending on how your cutoff switch is wired, the problem could be there. Loose wire, bad switch, etc. Same story: Your battery was most likely disconnected.
Chuck S is right. It can't be the fuse since a short charge worked. But you might have wriggled some wires when connecting the charger. Tighten everything.

My cutoff switch is wired on the positive. My father-in-law who is a retired electrician told me to wire it that way. I questioned whether it was the right way and got the old "just do what I told ya" routine. Later he explained that there can still be some draw even if you diconnect the neg. I personnaly dont see how, but I know very little when it comes to electricity. I have checked the fuse and it is good. The brake safety switch is good. I know a TV will not fully charge on a short trip. But I was plugged into shore power. Shore power charges the battery also correct? I think its a bad battery. its been on the charger now for hours and the needle on the charger hasnt moved. I'm going to buy a battery tester that actually puts a load on the battery. It will tell me its condition. I can always use it for my vehicles also. Thanks to everyone for helping.
