I picked up a POTC yesterday a HUO,1 owner machine with only 400 games on it.All was going great until when the ship is hit it does not register that it has been.When it is hit the ball is usually held there for a bit by the magnet or pop up post i am not sure as i was not really looking at what holds it there,but when it is hit now it just comes straight back down.Is the small red light up in that area an opto that registers a hit and activates that it has been hit and in turn gets the magnet ect to hold .Any help would be great,Thanks Tony.
