Yea I had that problem but it was a battery separator similar to this link.

What year is your van and which do you have?
Basically I had one of my starting batteries (diesel) go bad and it was burning up the separator. It was difficult to find mainly due to the fact that Ford told me 3 times both batteries were good when only 1 was. The van was starting off the house battery. If I had let it drop much (the house battery) the engine wouldn't have started . SMB changed out a few separator's before I found the problem. BTW taking off the ground wire is one way SMB tests the starting battery system. With the ground off will your van start?
From what I remember if you leave the radio switch on it will drain the starting battery I THINK.
Somebody else had a wire hitting the frame and the insulation rubbed through.
As far as the refrigerator (and the entire post) this would be a good question for John K.
