I have a Barker tongue jack on order...from previewing the install directions, I don't know that you did anything wrong. The jacks use the frame for ground and typically connect to the postive terminal. The power lead usually has an inline fuse for the jack from what I gather.

I have two 6 volt batteries and there is a 30 amp fuse going to the TM, but there is also a 75AMP fuse between the two batteries. Did you check/test both fuses?

If both fuses check out OK, then if the fuse you removed was the 30amp that feeds the TM, I would also check the fuse holder, especially if it is the original glass fuse holder. They are known to cause problems and perhaps when you took it out and put it back in you are no longer getting a good connection.

From reading this forum, I replaced the glass fuse holder with a Mini-ATC fuse and holder.
