Hello, I'm looking to know if we can repair our own converter? We have a trip planned for Memorial day and our pop up won't, well, pop up! We plugged it in to outside power source and tried a new fuse, nothing. It does a beeping sound, like a dead battery inside maybe? But we called a local shop and they guessed the problem is the converter is fried and we'll need a new battery but they cannot look at it until 6/2. How difficult/expensive may this be to do ourselves? Can we just get a new battery and last the weekend until they can fix it? We are first timers and the lot we purchased the camper from kinda sucked with giving us a 101. Any help is appreciated!!!!
