I have a Ghostbusters pro that had me stumped. I noticed tonight that the flasher over the librarian scoop was constantly lit, and none of the inserts on the lower playfield were on. I tested the node board bus. Good. Tested the node boards. Good. Reseated everything on node board 9 as well as reseated all the cat cables. I tested the inserts and none if them lit until the 80’s. Also only the slimer flasher and Stay puft lit on their tests. I unhooked the molex for the flasher over the librarian. Also the “fix” for that flasher is on the machine from the factory. The node boards are on and working based on the flashing orange lights. Can anyone steer me where to go from here? I had a node board issue on this game a couple years ago but all the lights in the lower third were out then. After Stern sent me 2 faulty ones I replaced node 9 with a new one.
