i have a monopoly pin thats pop registers but does not kick ball when it touches the pop? Anyone know what could be the issue?
 
Sounds to me like the connection from the switch->cpu is fine, but from CPU or Power -> solenoid is borked somewhere. Depending on what's actually causes it to fire on that machine...pretty sure both my machines are "dumb"...they just fire whenever the switch closes and there's no CPU interaction needed. Don't know about the DMD gen stuff too much, but if they work that same way, might be a bad connection between the switch and the solenoid.
 
Go into solenoid test and see if it works there. If not check for broken wires at the coil lugs first, especially the tiny ones coming off the coil to the lugs - they can be hard to detect.

Then follow the wires back to the driver board and check for breaks at other coils.

LTG :)
