Also, your ball lock issue sounds like the ball lock switch not registering..
thanks i'll spray it with some deoxit
So I think the ball lock is registering because the pin is changing modes: lights dim, music changes, etc - basically it goes back to the new ball start where you're shooting the skill shot. It just isn't ejecting a ball into the shooter lane.
Thanks for the help.
