Hi all. Just got a great example of Space Odyssey and I'm super excited. When I got it, it actually started up and played okay. I spent some time cleaning the playfield and replacing the rubbers and when I went to start it up again... boom! This scoring issue popped up. Basically, when I hit the Start button, the game continually adds 10 points... forever and ever. This is not triggered by any switches or actual scores--it happens as soon as I hit Start.
Game was missing keys, but I picked the backglass lock so can tinker around.
From my past experience with EMs, I'm assuming this is a simple leaf switch issue: Either a dirty contact that needs to be filed or else bent switch making too much or too little contact at rest. Does anybody have any ideas on which switch it might be? Or any other suggestions on fixing this? Thank you!
