Long time lurker first time posting. Bought a system 9 space shuttle from my aunt, they had issues with the machine and it’s sat unused for quite a few years. I took it back home, got it powered up, tossed fresh batteries on the board and went through the memory chip test using the diagnostic button. It always comes back as 0, it also will cycle through attract mode as it should. I confirmed that the game is set in free-play but it will still not start a game.
When the start button is pressed you hear a few of the solenoids fire but the thrower will not move the ball to the ball ramp release & the flippers are unresponsive. The only time the flippers work are when you run through the solenoid test.
Any ideas on where to start on trying to hammer out this issue? I grew up playing on this thing and would like my kids to be able to experience it as well.
Thanks in advance for any help
