Thanks for your help guys,i checked for any loose wires ect an all looked ok.I reseated the 2 opto plugs and it is working fine.I have played a dozen games since and all seems good.As i have never played this game before could you just confirm for me that all is working as it should.The first time i am going for the ship after 3 hits the ship starts rocking until i hit it the 4th time then it lowers all the way.After i have lowered it the first time and am going for it again after the 4th hit the ship rocks backward and forward but does not lower all the way as it leaves enough room to shoot the ball through as it rises but not enough as it comes back down.Is this a type of skill shot as i do not know what mode i was in ect.I am very impressed with this pin as not only does it look great it plays great as well,there is a lot to shoot for and the toys suit this game and the sound and lighting are also spot on.I have played some of the so called higher end pins and this is way better in my opinion.Thanks.
