Hi all,

I have a Sure Shot machine which has been dormant for a number of years. It appears like most functions are working with the exception of Ball Return and Bonus Unit Scoring. When I manually push the ball across to the lane, it does advance the Ball Unit and start the game:
1. Game scoring and lights appear to function properly
2. Bonus scoring does not seem to be activated when the ball passes through to the ball return switch. In fact I see no activity of the "q" relay which I believe should control the bonus scoring. (If I manually hit the "q" relay three times, the bonus scoring will take place, and the ball return activates)

Any thoughts on the likely source of this problem?

Cheers,

Problem solved!

Once I realized 30v was missing at the ball return switch, I was able to locate the mis-adjusted switch on the gear side of the bonus unit.
