Nothing works?
My fifth wheel trailer sat for 4 years and batteries went dead. Installed new batteries yesterday. Nothing works, so I plugged into house with 15 amp power. Everything works? Do the batteries need...

Necessary Cable NOT connected when batteries/cables replaced. For example, we have four cables connected to positive on our battery. Leave one off, something isn't going to work. I didn't combine them into a common terminal, but I did tape them all together to help avoid missing one.
