Working on a Monte Carlo (Bally, 1973).
The ball won't eject from odds hole, it stays there and the points increase forever (or until I manually remove the ball). The evens hole works as it should (which means that 7C-SCM can't be the problem).
I have cleaned and adjusted the odds hole switch. I have done the same with the odds hole relay (difficult to reach).
Since the evens hole works, I dont believe that 1C-SCM or 10C-SCM can be the problem.
