Picked this up last week. Took awhile to get it running but I have one pesky issue I can't sort out. Schematic is on ipdb.org but I can't trace this to a switch I think might be on the score motor.
Game plays great until you drain ball 4. It kicks out ball 5 and briefly shows ball in play 5 for a second and immediately goes to game over and lights a match number. If I manually activate ball trough kicker switch to drain ball 4 and then activate switch on exit of trough to advance to ball in play to 5 it seems to work fine but when done with a ball in quick succession as it does in game it goes to the game over state I mentioned 97% of the time. For some reason I'm having trouble locating problem switches associated with game over relay on schematic. Maybe it's because I stared at it for too long tracing all the other issues or Who knows
Also if I set game to ball 3 it also does same thing draining ball 2 and ending game as it shoots out ball 3.
Video of it happening at end of game. You'll here the ball shoot out for ball 5 but game goes dead.
