My 30xxx SB has a center entrance and the 120v and 12V boxes are at the top of the steps, towards the front, behind the louvers. My converter is on the front side of the vertical board that the 120v breaker and 12v fuse boxes are mounted on. There is an outside access door, ahead of the entrance, just for the converter and some auto reset 12v breakers. Flash, I just remembered... There's a thin luan partition to protect the converter so it's a little hard to see behind it. I remove two screws in that partition to expose the converter. Hopefully you just have a blown fuse in the converter... If there Is one. Craig
