Just set up a new to me Harlem Globetrotters that was working fine when I bought it a few days ago. Now that I’ve moved it it starts a game and kicks a ball into the shooter lane, but then nothing - as far as I can tell no switches register and no solenoids fire. However the solenoids do all reset when I start a game, so I believe this is a switch issue...I feel like I’m missing something simple and obvious. Any ideas? And just to confirm, only 1 ball installed in this game, correct?
