i have a firepower that is resetting the board when either flipper button is pressed. It has a rottendog replacement main board. I dont know the background history of the game. if i start a game and not touch the flippers everything works as it should. As soon as i touch a flipper i think the main board goes in safe mode. I have checked the connections on the power supply and those are all good. i am wondering what else could cause this problem. Maybe the bridge rectifier?
any help is greatly appreciated.
