Issue: 1974 Gottlieb Top Card is scoring through its 1k point relay during the ball change as if it has “bonus” which it does not. Fires about five times. This game has the AX/BX reset relay but I’m not sure if this is the issue. Suggestions?

It’s definitely the L relay that’s firing. It will also complete the 1k unit (back to zero) without the 10k carryover firing. I was thinking about vibration causing a 1k switch to connect during ball changes but wouldn’t that happen at other points throughout gameplay? Also, that doesn’t explain why the 10k doesn’t turn over during this. It does during normal gameplay though. It sounds like I’m gonna have to trace wiring to see if a switch out of adjustment. My first check is the reset relay. It’s such a little prick. I’ve had this game for two years and, since I don’t play much anymore, EM switches don’t like to sit.

Solved. One of the switches on relay A was out of adjustment and was not opening when the latch moved. Obviously from not being played for a while. Switches on that relay have very little travel. Thanks to all that responded.
