Along with posting the problems you should try to copy and post the schematic if you have it.

Hi pinballdaveh! The hit unit only works if i keep the runout switch closed. I checked all switches but I must be missing something.

Maybe coil smoke will chime in. I think he has this machine. Baseball pins are some of the hardest machines to work on. Without the schematic and maybe a video of the problem, makes repair very difficult.

Hi! I was able to fix my hit unit. My other problem hitting the single should score 100pts. I get 300 to 200 points every time. Any idea what the problem could be?

No I canít tell whatís the problem without the schematic. Like I said baseball pins are complex.
