Checked out the two small aux driver boards. Found one cracked solder joint on a pin. Then found this small link between two pins on the other board i removed the link. Turned it back on then the middle playfield gi didnt work so put it back in.

Looking at the wiring diagram im pretty sure its not sposed to be there.

Also i checked out that 555 globe hidden next to the solinoide board. I noticed some wiring had been changed. So im a bit confused on it all looks like i have a bit of wiring to follow and some more looking at the drawings.
