The game will reset as soon as you hit the Right Flipper Button. To be clear, the right flipper coils never fire. So I don't think it's a low power issue (like on WPC games where you hit both flippers at the same time and the game resets.) I have tested triggering multiple solenoids at the same time (pops, left flipper) and the game does not reset. It's the right flipper button inside the cabinet that is causing it I belive.
There is a spark at the connectors when pressing the button, and the game reboots. I have cleaned the connectors and the wiring looks fine, but it does spark every time. There is no diode on the switch, but I don't think there is supposed to be.
Any ideas? thanks
