Hi chatplume51 ... congrats on your new game, but sorry you're having problems.
A couple things to try:
- Remove the balls, make sure they're not magnetized. (Touch a metal paper clip to each ball and see if it "sticks".) Magnetized balls can get gummed up in the trough and confuse the system, sometimes leading to extra balls getting served. Also make sure 6 balls are installed.
- Using the Switch Test, make sure that each trough switch lights up correctly when you drop the balls back into the trough... when all the balls are back, 6 trough switches should be lit up, no more, no less.
Odds are that it's something simple, like magnetized balls, or a wiggly connector somewhere since you just moved the game... we'll getcha sorted out so you can get back to playing.
Also don't hesitate to submit a service ticket requesting help... <https://www.american-pinball.com/support/service/>
