Start with re-seating the connectors, seems like a popular problem after a move. If the balls were in it during the move, check for stuck or bad micro switches in the ball trough.

Go into your tests inside the coin door and enter the switch edge tests mode to see if the pin is seeing one or more closed. Sounds like one near the ball through may be faulty. Also... Like said above ^ reseat all your connectors.~SpOoKy

Sounds like a switch issue or connector. Make sure you do not have a switch closed. Check each switch in the ball trough. Also make sure a wire to the a switch did not come loose.

Ok, stupid question time - is there 3 blls in the game?

I think so. I know two will work. Don't you have that sticker on the lock bar receiver assembly that shows how many balls go in the diner..

Game uses three balls. Take balls out and put game in switch test send one ball at time into trough and verify switches are working and game sees all three balls, also check that you didn't break wire off any lane change switches

I will need to looks at my game for sure but on some system 11 games they are mounted next to the end of stroke switches on flippers .Do a thorough inspection it could be one of the plugs on the circuit board was pulled loose also its not uncommon to have a wire under play field break off at solder connection

Probably not a loose wire, more like a bad micro-switch.
