help! i screwed something up on my world cup soccer.. i pulled out the power driver board and dmd controller board to test another game and when i put it back in it blows the 7a fuse at f112 as soon as the game boots up and the ball start to spin. so the game starts but no solonoids. i took photos before i unwired it so i think i wired all back up correctly.. any ideas what could be causing this now?

BR 1 is A-OK
BR 3 is mostly ok its reading about a .6 instead of a .8 on pos to neg test (legs were normal)
BR 4 seems a little out of whack though when checking pos to neg it fluctuated pretty wildly first negative then creeped up to .75 thought that was odd but wondered if it didnt have something to do with this jumper someone put in the back.
let me know what you think.. replace br 4?
I have another powerdriver board i stuck in there and same fuse blew
