Batman Forever/Sega for the most part this game is playing and working fine. I do have this odd issue when the game sits in attract mode the coil to advance the ball on the trough will fire then a few seconds later the ball launch coil will fire. problem is intermittent and does not occur when the coin door is open and those 2 switches aren't closed. what should I be looking for ? all switches on the coils and trough switches seem to work correctly and have diodes attached.

I checked all diodes and connections as advised on trough switches. I then held the coin door buttons closed with left hand & disconnected the front facing side of trough opto that is in same column. coils stopped firing then put opto connector back on. It has not done it since, but game is on location will recheck tomorrow. Thanks to everyone who weighed in to help!!!
