I'm trying to figure out how the right flipper opto board or flipper In general is at all related to the right loop optos on DH. Not every time but often during game play the right flipper will make the magnet opto(right loop) register. I've cleaned the right loop optos and they work as they should, but about every third flip will cause it to also register.
I can hold the flippers in and lightly press the button and it will still register, so I'm fairly certain it has something to do with the optical circuit not so much the flipper coils, vibration, etc. I don't see in the schematics how these two things relate, anyone point me in the right direction on this? Thinking something on CPU since the fliptronics board and 16 opto board are independent of each other.
