Quoted from AmericanZen:Yeah looks to be correct, Gray up and gray red down. I wiggled it and the start light came on and the action button light. But when I opened the coin door and closed it again it turned off again. I guess I’ll be calling Stern tomorrow
Your connector in the backbox is probably wired reversed for the power cutoff switch. Verify it looks like this one.... (I'm thinking yours will be the opposite at this connector)

If this IS the case, you can safely swap the connectors on the switch at the coin door and it will work right. But verify yours is REVERSED from what this pic shows in the backbox.
