This is my first EM game/repair! I bought it in non working condition and so far I have cleaned up the back box units and score reels and fixed a few small issues with coils locking on. I can now start a game and all playfield features are working I do have the schematics but I can't find the last fault of no 'game over'.
The remaining problem is that the game never ends! Once powered up, the swinging targets start moving and the flippers are always active. The 'game over' lamp never lites and the match feature doesnt lite. The trough switches were all bent open when I got the game. If I adjust them to close when all 5 balls have drained, the score motor runs continuously. If I leave 5th switch open, the motor stops and I can reset a new game. The actuator for the out hole switch is also missing but the drop target does reset after each ball drained.
To summarize: power on - targets and flippers work I can start and play 5 balls. When they all drain (trough switches bent open) the targets and flippers still work and no 'game over' / 'match' behavior. I can hit the replay and play five more balls, over and over
