Try to look at a pinball machine this way. Especially if you have the manual and can see the picture of the mpu board. It circles areas of the board that show what's the primary functions are. There are many systems on a machine. The controlled lights are one system. The coils that fire are another system. All of the switches are a system as well. So they're literally is a physical matrix of wires connected to switches. They plug into the mpu, I believe it is on the bottom right of the board I will have to double-check. There are two sets of wires I believe one is green and the other is white. All the switches interface with that big mpu board and based upon which wires are crossed the game interpret stats as a switch being registered. The game is somehow seeing the slam tilt switch closing when it obviously is not closed. There is something criss-crossing that is causing the game to think that the slam tilt switch is closing.
