My AC/DC Premium ends the ball randomly during play. It occurs in about 25% of my games and I cannot identify any pf activity that triggers it.
It isn't tilting, as it adds up the bonus and acts like a normal EOB.
I am assuming this is caused by 'closing' the 4th trough switch, and have visually inspected everything on the trough and the row and columns on that switch and don't see anything grounding.
Any ideas on where to look next?
