Does switch #67 show as closed when the ball is sitting in the outhole during test 18? If no, turn off the game and adjust the switch. Check the corresponding switch diode (1N270) Run test 18 again. If yes, then

Does the #9 coil fire in solenoid test 17? If yes, inspect connections (A1J4-T) if the coil still doesn't work during game play. If no, look at the driver transistor Q59 as the cause.

Well, after looking at your pics, my earlier post should still apply but not if the problem is actually in the aftermarket CPU board. Does the test portion work the same way on Ni-Wumpf? It also looks like I need to start out asking if the boards are original or aftermarket from now on. I usually only troubleshoot original System 80 boards, though aftermarket boards do the same thing as the originals, they are totally different animals.

All I can suggest at this time is to re-pin your CPU board connector for switch matrix (A1J6) since you had to replace the original CPU board. If the old board was replaced because of alkaline damage, it might have also gotten into that connector.
