2002 I just removed the factory battery and forgot which black/white went to what and got it backwards (black goes to red not black? ugh). Nothing was happening until I plugged in the camper power, and I heard a beep then everything died. Even 110v nothing working I am hoping there are some fuses I can pull and not something more serious There is a very old looking fuse one of the the 2 black wires going to the battery, (its sealed metal and kinda rusty) I assume that would be blown as well but don't see how that would stop 110v plugin power from working? Looking at the manual there are some fuses in the power converter, I'm going to check those first.
