What does the switch tests report for the non-working switches?

Are any switches closed? Should have a 0. If you press and hold the coin switches and the credit button, they are all lower numbers than 17, so they should show as long as you are holding them shut.

Did you change the switches, wiring, or diodes on the switches when you swapped playfields? You likely have a diode flipped or wires in the wrong place somewhere in that case. Did it work fine before the swap if you didn't change any of the switches and associated wiring?

there's a lot of variables here since you just completed a swap and you're going to have to divide and conquer them there's not going to be a magic bullet. If alltek included any of the roms where all the closed switches are shown that could provide a clue, all the switch test currently tells you is that there's an issue with 17. If 17 seems ok then you need to check all the switches.

Also, disconnect the playfield switch harness (upper right on the mpu board) see if you still get 17 closed or if the door switches then work
