I just got the game with both Bill Ung kits installed and at first the back box gi didn’t go out during strobe multi ball or video mode. I did some research and realized there were no jumpers installed. So I installed jumpers on row 3 on J20 on the board. Now it works in strobe multiball but I do get some fast strobing on some insert lamps during the mode sometimes also the gi in the backbox flashed a couple times when hitting the drop bank. Is this normal?. During video mode the backbox stays lit. Is this not normal?
