Just received this game which would start, but most of the feature were not working such as play field lights not changing with a feature and match lights were not showing. The Advance Unit and the main bank of relays attached to the bottom of the play field were froze with gunk. I tore them down, cleaned and adjusted. Everything is working the way it should now except for the game ends after the 1st ball drains. I can see that the "last ball and game over" activate once the ball in play drains had hit the 1st trough sw. I do have the game set for 5 balls. Game is not set to free play. Have only worked on a few EMs over the yrs and am a little rusy. Any suggestion on were to start?

There are only 3 trough switches and seem to be functioning. the "last ball and game over" activate once the ball in play drains had hit the 1st trough sw

Mark,
You were absolutely right about the trough sw. The fish paper was worn through a bit on the 2nd trough sw. Replace the fish paper and is 100% working. Thought I had checked them out real well, but once I pulled them a part I could see the wear spot. Thx a bunch!!

Agree, that and my schematics are not that readable after all these yrs. It's funny as the trough sw's were the 1st thing I checked....just not good enough it appears. Thx again
