Im new to the SS pins and still reading up on the Sys 9 also but having trouble diagnosing an issue. Pin worked fine when purchased but started having an issue where the drop targets wouldn't score when all 3 were hit, the timer would just run out and reset all 3 targets. Tested each target and the game recognizes each target when dropped by itself. At the same time the game will identify when the first ball sits in the multi ball trap but when the second ball lands there it doesn't and the balls get stuck waiting for multi-ball mode. Around that time I did change out the batteries and reset to factory settings but doubtful that was the cause.
I appreciate any help and advice you all give me.
