Just got a Williams Space Odyssey and thought it was working OK. I played a few games, then it started going crazy.

The big wheel (scorer) below the play field keeps spinning, and the two ball kickers by the flippers keep kicking on and off. If I start a game it goes even more crazy and the 1 player score starting counting up with bells ringing, etc.

Here's a link to a video showing the issue -

Any ideas where to begin?

You have a stuck playfield switch that scores 50 points. Check all 50 point pf switches starting with those kickers.

Mikala That was the problem, the left kicker switch was stuck down. I un-jammed it and it works again.

Another question, my moving target is not moving, what might causes this and what can I test on it?

Is the moving target motor getting power?

HowardR - I measure 45 volts AC at the two motor contacts (the two black wires).

Then I have to think the motor is bad. Unsolder one wire from it and check its resistance with an ohmmeter. I suspect it will read an open circuit.

Either the motor is bad or it's seized up from old solidified grease or a piece of debris jammed in the gears which is easy to do with the open frame.

Good point, @polyacanthus. Those are possibilities too. I upvoted your post.
