Since I have had this pin (my first) It has been a very good machine. I have a problem with Switches 18, 38, 58, 88. They are showing up as a error. They all seem to be good as in continuity, but don't show on the switch test. Any ideas?
 
Sounds like that row on the matrix has a problem.
How's connector J209 look on the CPU board? Specifically, pin 9. Is it corroded or making good connection?
 
I did a quick check last night. J209 Doesn't have a connector on it but J208 does. The wires seemed to be in good shape. I didn't pull the board to check behind it, but this machine is pretty clean overall. I believe it has all it original back box boards and connectors that plug into them. Non of the boards have any burn marks that I can see. I checked under the playfield on those switches that show up as having a problem but didn't see any broke wires. This was my first machine. I have a T2 that had a bad hack on its Driver board that I tried to fix, and lets say now the T2 is down hard till I order a new Rottendog board for it. The Demo man has been pretty trouble free since getting it.
 
Took a look at it this weekend and found one switch with broke wires. I fixed that and the machine is good to go.
