Quoted from Silkenone:Any fellow owners ever come across problems with the eddy sensors?
Mine aren't working at all - yet it's not showing up as an error (no credit dot), which seems odd.
The eddy sensor board has an adjustment pot which will sometimes get out of adjustment with vibration. It probably wont show up as an error unless it was stuck in the closed position as it's normally open till the ball rolls over the eddy sensor which triggers the switch closed. Have you tried adjusting the pot? Their is a red LED on the board, I believe you turn the pot counter clockwise till the LED turns on then turn the pot clockwise till the LED turns off and then back it up just a little. I hope I didn't get that backward but you will figure it out wile adjusting the pot. Put the game in switch test and run the ball over the eddy sensor and see if the ball triggers the switch . I cover this briefly in my video around 12.26 into the video.
