So I have an old Grayhound skill Crane. It has a single board with 3 relays. I cannot get it working at all. All I can get it to do is reset the claw back to the home position. That's the only sign of life in it. I recently found a similar board on eBay. Put that in and the same thing happens. I might need to start at the start. I can't get it to coin up to see if it actually does anything else. I'm thinking that maybe all my controls are wrong. There's over 20 pins on both sides. But the side where the controls and coin mech hook up only has like a third of the pins being used. Any help would be much appreciated.

Look close at the harness on the front (the controls) and see if any of the pins are broken off of the connector. I had one with that problem before.

If you put the claw to the center, it goes back to home, correct? If so most of your stuff is working, you're just not able to coin it up.
 
Also check your crane and claw head position min/max switches if it has them (not too familiar with Greyhound). I had a bad switch on an ICE crane and it didn't act properly. It not reading the 2 (3 including claw) home position switches, it might not accept credit. Make sure they are hooked up correctly (Normally Open or Normally Closed).
Just a thought.
