Here is a strange one. Just bought a WCS, and it is working perfectly apart from the trough 3 opto which is saying it is open even with no ball in the trough. What this means is the game kicks out two balls at the start of the final draw multiball. After checking the led transmitter for trough 3 under a camera, it looks like it isn’t emitting any color. I have ordered a replacement board, but my trough boards look strange and I don’t appear to have the 7 opto Board in the top left hand corner on the playfield. I will post some pictures - has my trough opto wiring been modified? How can it function without the original 7 opto Board? Don’t exactly know where the trough opto board wiring is going.
