HELP Switch Polarity problem

[Jailbird]

Hello all. First post, so thanks in advance. I have a 09 Saber that I just pulled out of storage and put on our lot. The slide switches and the switch for the jacks are now operating opposite. I push IN and the slides go OUT. I push EXT and the jacks go in ect.... The guy that owns the barn I keep it in said he had to charge the battery to operate the jacks to move it, other than that it everything worked fine when I parked it. One of the 30 amp breakers where blown also. I'm new to RVing so any help will be appreciated.

Sounds as if the batteries are hooked up wrong.....can cause a mess.
