Quoted from TecumsehPlissken:

Still digging on this one & I have discovered a few more things. Its not just the 2 yellow stand up targets that give a ground row short message. All 3 of the yellow targets do that & in addition I noticed that All 3 of the Right side bank white stand ups #44,#45,and #46 do it as well. They individually reference a different row on each one. So yellow top right target registers ground short row #1, center yellow target row #2, and bottom left yellow row #3 and with Right side bank switch#44 same message except it is for row #4 , #45 = row #5 and #46 = row#6. Also noticed in switch test that if you hold the outhole switch closed and then close any one of the other 3 trough switches Left, Center, or Right the switch test shows "Opto made loop" which is the last opto on the super charger loop ramp. In addition to all of that I noticed that the outhole switch does NOT have a diode attached and I think it is supposed to have one. All of the other trough switch's have them. Could a missing diode cause All of this?? I have traced wires and connections all over and over again I have been unable to find any shorts or broken wires/ connections touching etc... (yet) Lastly I am posting a couple pictures one is of the Outhole switch , the other is of the DMD in switch test showing one lone switch closed on the left side of the screen that I have been unable to identify yet. Can anyone tell me what that switch is so that I can check it? Thanks much

Thanks for that! I can at least rule out chasing that down now.

Any chance I could get a good picture of the outhole switch on your game?
