Battery won't run anything when unplugged

Hello,

I have a 2007 189FBR and everything works great other than I cannot figure out why my battery won't run the lights, radio, etc. when it's not plugged in. I thought it was the battery, so I bought a brand new one and charged it...tried it....nothing.

Does anyone have any idea why the battery isn't powering the camper when I'm unplugged?

Thanks!

p.s. I'm 100% sure I didn't reverse the terminals. The battery is hooked up correctly.

When I say unplugged, I mean - when the camper isn't plugged into electricity.

I'm going to ask what might be a silly question... Have you checked your battery disconnect? Many times that gets pushed inadvertantly...when your battery disconnect is used, it, of course, disconnects the battery from everything in the TT...

If you don't have a disconnect (the '08s had them, not sure about yours) the other possibility is a blown fuse in the positive cable to the battery. If that is blown, it, too, effectively removes the battery from the system. The fuse is located in the black wire w/white stripe (pos terminal of battery), usually between the front bulkhead of the TT and the battery box...

Check the battery disconnect if you have zero, zilch, nada battery on anything..light, fridge, propane detect. I just found that lesson out the hard way over Memorial Day weekend. Someone told me to check and sure enough we had accidently disconnected the battery, we were totally off grid for 24 hours, but funny thing solar panel worked like a champ-just no battery to go to!
