I am getting confused I hate to say. I'm trying to do the switch matrix check on my Time Warp pin, and even after following the marvin3m site, I'm still not making much progress.
The marvin3m site says that when you run the switch test, the number showing in the 'ball in play' field is the last switch that closed. If I run the test, the number showing in that window is currently switch 24. I can't see anything physically wrong with the switch or the wiring, and in gameplay that switch (and solenoid) are both working fine. So, I did what it said on the 3m site to do next: I unplugged the connectors 2J2 and 2J3 from the driver board to see if that would make the error go away. The display no longer showed 24, but it now displays #31 with the connectors off. That is the switch for the 5-drop target, which also works fine in gameplay as far as I remember. Also, if I go around and close various switches on the playfield by hand, the display does update with the switch I'm checking.
Basically, switch row 1 (white-brown wire) is out with the exception of 1 connection (the one going to the 5-drop target), and switch column 2 (green-red wire) is pretty much out.
I'm no pro at this stuff, but I can maneuver through the diagnostic tests and do most of what people tell me to check, and I can now solder (FINALLY), so any help would be greatly appreciated!
