I am doing work on a Williams Space Odyssey and the machine tilts when the ball travels thru the spinner lane and activates the rollover switch. Strangely, the manual states that this switch is connected to the tilt relay thru the ball index switch, so it seems that this is happening by design, which, of course, is not true. Can anyone describe the normal operation of this circuit?

Thanks, Rolf. There is no gate on this pin, and the spinner needs to score before this rollover can be activated, anyway. If I can't find the bad connection causing it to tilt then I will just disconnect it.
