Ok guys I got the trough issue fixed and the game is playing but it's doing something odd during game play.
There are times following a ball being locked that the game kicks out two ball instead of one in rapid succession.
From what I can tell, it only occurs when the ball is locked in the right lock scoop.
If the ball is locked with the center 'T' target in the down position, a second ball is kicked out. I this 'T' target is up, there is no double kick out. But, the next time that the center target is dropped down during gameplay, it registers as a ball having been locked and the 3rd ball is kicked into the shooter lane.
It seems to me the problem is related to the this center T drop target and the right lock scoop.
None of this is happening when the first ball is locked on the left side of the table.
