My mom got this Gold Wings for a few hundred bucks. She bought it as not working. Everything lights up and the fuses are good. I can start a game if I manually push all the balls into the loader but it will never kick a ball into the loader on it's own. Sorry if I'm using the wrong term. By loader I'm referring to the spot right before the balls are popped out into the lane.
I ran the diagnostic and it wouldn't fire any of the solenoids except for #8, the knocker assembly. I spent a good bit of time making sure there were no broken wires or loose connections. Reseated everything I found. Any help on a next step would be greatly appreciated.

Thanks!

Checked all the solenoids and they seem to be fine. Going to look through the schematics and see what's what with the boards.

Todd Tuckey's ground mod repair fixed the issue.
