Got this Williams 1968 lady luck I'm working on, the game starts correct but once the ball rolls over the runway roll-over switch the scores reset back to zero .

It's resetting both the 21 hand and the normal score reels above the 21 hand.

I will have a look at it.

When I close the runway switch the score reset relay is pulling in, score reels all go back to zero and then the score reset relay deactivates.

Bump

Yes the reset relay also fires when the player reset relay fires, looked at the the game over relay switch lugs none of them touching ajusted the switches the game now is only resetting the score reels maybe 1 out of 15 times .

Thanks Mark you were spot on, the short was at the game over relay one of the switchs was touching the arm lever that resets the switchs I put some black electrician tape around that reset lever if anyone has a better idea please let me know.20210426_105313 (resized).jpg

It's that arm lever has a lot of movement in it.

Last problem there is no score at player 2 it lights up but no score, when the game clicks over to player 2 the score goes to player 1.
