I've been resurrecting this survivor and have come along way in getting it working. Have the schematic and a handful of parts from Steve Young. Most everything is working now except one function. I have been troubleshooting for many many hours the counter function that rolls the 10's over to the 100's wheel. It works on player two but not player one. The tens and hundreds do roll on their own but not the passing from one to the other after the 9 count.

I've been all over the schematic and am now focusing on relay X, add on first 100's unit, yellow and blue wire that I believe is switched by the counter wheel I suspect. The second player switch for the same is in that path which seems to work. I don't know which switch/ contacts in the counter that trigger this. Not really labelled on the schematic. I've done lots of visual inspections but don't see anything that is obvious.

Funny thing, I somehow trigger a state where the second player counter and wheel counted up by one point continuously all the way up past 1000. It was a great state for troubleshooting / testing but don't really know how I triggered that (fat fingers somewhere). Any chance that is a test mode that I can trigger, would be nice to have that mode to troubleshoot my issue above.

I'm also unsure how to properly add a second player to a game. I seem to get there by pushing the white and red buttons multiple times but it doesn't always work or stay engaged for two. It would be great if someone could share the proper way these games add a second player.

Thanks in advance, Rick

Thanks Currieddog for the tip. LOL I read that document so many times I could write it. So this issue wouldn't be in the actual counter assembly itself?
