Quoted from robertmee:Bad coil or diode would be my guess...have you tested both?
And probably bad transistor/etc on the driver board, since it won't even fire unless you ground it

Sounds like your switch isn't registering. Clean it with a business card, make sure it's closing, check the diode, etc
Quoted from robertmee:Take all the balls out of the game. Go into switch edge test mode. Roll each ball into the trough and see if the switches all register correctly. Also check the shooter lane switch with a ball. It sounds like the game is not seeing the ball drain, which would be the first switch in the trough. When this happens is the game advancing the ball on the DMD? As a test, go into two player mode. Let player 1 drain...Does it recognize it's player 2's turn and kicks out a ball?
This isn't a DMD game. There's only one ball and one switch.
