Quoted from Phatchit:Here you go . Everything was working but the scoreboard . The section looks burnt . I also was curious what kind of diodes are used on this board . I can't see any markings on them
So somewhere back in this thread. I had a issue with my scoreboard ribbon cable (data that is gray). THe main issue is that when it goes from the scoreboard under the ice, the hole in the top to the base, is not aligned for it to just drop in. It is off center, so the cable has to bend/fold to make it in the hole. HOWEVER, it usually just became cut and then grounded out on the edge of the hole, or the player rod wore through the ribbon. This grounding and break would then burn the connector on the PCB/motherboard. Once that happened well...you could wreck the board or like mine, they made some hacks to make it "work" however the ribbon was still not fixed under the ice.
So in your pics above the gray ribbon cable is not plugged in on the MOOG board. You can get new ones from maybe ICE? but I got mine from Boston Pinball. I also order from digikey or Great plains, a new molex connector for the MOOG board. When swapping the connectors, you will want to clean off any carbon or it will act as a wire and bridge more connections or start a fire....don't ask. I also see one of the power connectors on the moog looks a tad brown. I'd check that out as well. You may want to remove the board, clean with rubbing alcohol to get any burn/carbon off just in case.
THere is a manual I ordered from ICE for my game but the one from the pin repair site works too. You can see the pinout of the data ribbon as it carries power/ground and data for the shift registers (scores). I can also find my pics..... from before...If you need any more pics I can take them tonight before I button my game up and put the ice on. I almost thought about drilling a new hole for the ribbon, but currently I have the new ribbon make a fold over and tape that down so the rod doesnt touch the cable.
I also have added more wire management under the ice for all the sensors so they do not get rubbed by the player rods.

Ended up taking this to MGC and Rob Anthony some how got it working. There is a large hole in the PCB from the fire but the game works. I suppose I may want a replacement used MOOG as backup but I hope to have time with a baby and winter coming to get a arduino to run the entire chexx. We shall see.
Hope this helps keep another 83' chexx alive!
