I have a Big Valley I'm working on and I noticed the score motor will only run when both of the top switches are closed on the 1st switch stack. Normally the top switch runs the motor and the switch right below is open but, on this game, both switches need to be closed for the score motor to operate. I also have a 4 million bc and a nip it and those games operate normally. I attached the section of the schematics where I believe the issue is. The motor switch stack is 1c. Thanks for any help on this!

Your red arrow points at a Make/Break switch. Exactly like on your other games, when the normally closed switch opens and the normally open switch closes, the motor should run to complete its cycle.

I agree but it require both to be closed to make a cycle.

Then Inspect and diagnose this circuit with Alligator clip jumper wires

The nc switch on the 3th coin could be the problem, look if the contact is in closed position.

I've had problems with the tabs of the bally coin door microswitches breaking off. I would be sure the wire is actually connected to the micro and not 'floating'.

pinworks the tabs on the one micro switch are broken the wires are just hanging the other micro switch is completely missing. I was just adding credits manually would the broken and the missing microswitch cause this?

Well as a hunch i connected my coin door from my nip it to the big valley and the score motor seems to function properly with that door connected the big valley door is a mess see pics. Not sure what the yellow wire is going from the lamp to the start button switch but the game will not start without that connected.
Thanks,
Joe

This link should take you straight to post 42 in my thread about a similar problem. In this post I describe what I found that fixed the problem. Sounds like your situation is similar. A yellow wire in the coin door is involved!

I was able to work around this by connecting the two wires for the coin1 switch to each other this made it act closed like the actual switch would of done. will look for replacement parts to fix right.
