Quoted from Irishbastard:
Just a dirty potentiometer.... (Spray with contact cleaner, work back and forth)
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.
