Quoted from ryan1234:There is a small micro switch behind the back board. It reads when the ball goes along the trough.
It is #48. It is mounted to the top of the trough. It probably just needs bent down a little. This switch's only purpose is for "Destroy the Ring" to tell when the first ball has been knocked through.
Good Luck
that helped me...
just took about 30 minutes or so to adjust it, but it works like a champ now, thanks for the tip.
the switch sits in one slot, the arm sits in another, in between is a piece of the metal frame... I guess the arm was hitting the frame and wasn't making the switch.
was quit a trick to get it adjusted so it wasn't hitting that metal tab between the two.
