I have a 1966 'Subway' that I just bought. When the stand-up targets are hit, the machine does not register the 50 points. If I hold the target with my finger, the 50 point relay locks and the score motor registers the 5 clicks to score. The score reels will also register 50 points.
When the ball drains, the 50 points are not registered, ball count does not decrease, and the ball advance coil does not fire to allow me to use the elevator. If I hold the roll over wire in the trough, 50 points are registered, but the coil still does not advance the ball to the elevator.
When the score reels try to turn the 100 reel, the tens coil locks on. When the game is powered off, the score reels display 100.
1's and 10's are both scoring 11 points. I think I know the issue with this problem.

Please help a newbie to fix a classic game in beautiful condition.
