Prospector
Segasa-Sonic, 1977The game in question is Sonic Prospector which uses Williams parts
When I turn game on the score motor just keeps spinning. This in turn fires the two score resets relays in the back. Stuck in this loop and don’t know how to get out.
Thanks
You could start by figuring out which switch is closed and causing the Score Motor to run.

They'll all have an O-G (orange-green) wire on one side.
Quoted from megoman:This in turn fires the two score resets relays in the back.
Could it be the other way around? A switch on the Reset relay can turn on the Score Motor.

BTW, you might get more eyes on this in an EM forum.
