fuse box issue

In my 95.5 the (im guessing) main power wire on the back of the fuse box is loose and if it gets move at all the truck will completely cut off, you have to put the wire in just the right place for it to work right, even when in the right place my fuses are all the time blowing especially the brake light fuse, turn signal fuse, and instrument fuse. please help!!!

 

disconnect your battery and fix the wire. If its loose just check the connection and tighten it down. If its coming off the lug than just take it off and redo the lug.

 

what exactly r u referring to as the "lug"?

 

The connection. terminal lug or whatever they use to connect the wire to the fuse box.
