My Space Shuttle fires outhole coil multiple (6-8) times upon initial power on, boots up ok and goes into attract mode as it should. Then you can start a game and kicks ball into shooter lane but no speech (should say "ready pilot one"). You can play ball one fine (even get ball captured for multi-ball, will kick out another ball to shooter lane and say "ready pilot one"). Once ball one is lost it just sits in outhole and will never advance to ball two. Recently had Ed Cheung check the boards and all ok. Not sure what is going on, thanks in advance.

Ok, will do GLSP3022, thanks. Also want to mention in switch test 3 switches come up, 9, 20, and 47. Number 9 is the outhole. The other two are upper playfield switches and are not in the same row or column as the outhole switch. I am wondering if maybe one of the 3 ramp switches is not working causing it to "look" for the missing ball? The outhole switch, diode, and connections seem to be ok. I have not tested it with DMM nor checked other switches within its row or column. Will keep posted, thanks again.

Thanks EZED for the response. I will check those switches when I get a chance.

Found the problem. Outhole switch diode was shorted. Replaced and now we can complete a game. Still have a couple other issues ("U" switch in USA at top of playfield not working, one pop bumper not firing, and "air lock" (outlane gate) not opening when all 3 drop targets are down, but hey, we are up and running. Thanks for all the advice so far and in the future, Ed.
