Hey Ken... This has been an interesting exercise getting this machine working.. I've enjoyed the process of going over your place on the weekend and helping with the diagnosis of the issues. That power replacement board really did the trick with the reset. As you said you we are very close to getting Frankie working perfectly..."F-R-A-N-K-E-N-S-T-E-I-N!!!!!" is almost alive!

So if anyone is interested.. The latest update to this is that it appears that there is a constant 80v (not activated) from the + wire connecting the right flipper coil which reads at the coil end but not at the flipper board end. The other flippers that are working 0v when not pressed. My guess is that there is a short somewhere between the flipper coil and the flipper board so the next task is to trace that wire from the coil to the flipper board to find where the issue is.

If anyone has any addition advice it would be most appreciated.
