Refurbishing a 1970 Gottlieb Baseball which was a complete mess, except surprisingly for the play field. Got it working, except for some scoring issues, then did all the cosmetic repair - refurbish. Down to two issues.
Run scoring: the first, second, and third base lock relays were seriously gunked up, and out of wack. Have them mostly working except for the occasional stubbornly sticking third base relay. And a semi random problem which I think is related to the base runner unit. Will eventually get the third base relay dialed in. But the other problem, I have no clue. I think there is either a serious problem in the run unit, or the discs are out of alignment. When the top roll over switches are triggered, it is supposed to score 50 points, and lock the appropriate base runner relay in the on base position. Depending on how the base runner unit discs are aligned, the lock relay either works fine - or as the 50 points are scoring on the reel, the unlock side of the relay pulses 5 times, resulting in the relay not locking in the base runner on position. Have tried realigning the discs with no success so far. Also, and I think related to this problem, base runner positions are not correct a fair amount of the time, and triggering a double, triple, or home run does not score runs for the runners ahead of the "new" runner. ie: A home run with bases loaded scores 1 run, and not even that sometimes. Pics of the unit attached.
Notes: Have schematic, and all other original game paperwork as far as I can tell. Nothing gives real insight into how the run unit is supposed to function.
Hundreds / Thousands scoring issue: When the game is supposed to score 100 points, sometimes it scores 1000 instead. The 1000 point relay doesn't engage, the 1000 point reel just fires when the 100 point is supposed to fire. This is most common when the pop bumpers are lit for 100 points and very oddly are directly triggered by a ball. When I trigger the pop's by touching the skirt with a finger, scores fine. When a ball triggers it, sometimes scores 100 and sometimes 1000. My guess is there is a switch just slightly out of alignment in the 100 point reel. Or it has something to do with the ball triggering the point contact for a shorter time than when I use a finger. Have tried adjusting the switches below the pop, and in the pop relay, and in the 100 point reel, with no affect. And btw, no surprise to anyone here, these decagon reels are a pita.
Thanks in advance for any help.
