Hello everyone,

Restoring a 1973 Time Zone. Have done a considerable amount of work on the pin and plan to do a lot more. With that said I'm currently stumped on why the score continues to count the 1,000 switch over and over again, as the coin door switch continues to try to lock over and over again and the tunnel only lights up the thousand spot.

When I switch the pinball machine on all works and the score boards resets. The moment I hit the start button the thousand point continues to count and the coin door moves back and forth over and over again. Did remove everything to clean the playfield, replace rubbers etc. so with that been checking all the switches and they all appear to not be touching and working properly. When I push down any of the other thousand switches the scoreboard pauses and you hear the hum. However, when I push down the switch circled it just continues to count by the thousand as if it's not even working.

Any suggestions greatly appreciated

Thanks for the help. I've reset all the score reels to zero and when I start the game the 1000s reel does start to move and keep counting. If I turn on the 2nd player that score starts to move the 1000s reel on that side as well. How would I go about tracing it and problem solving from here?
