  • Keep s Scoring F

    Hi Guys im having trouble with one of my lanes keep scoring an "F" we have already disconnected the foul unit, we have switched the IO board and the CPU with working ones, changed ball detect and wiring, replaced pins in the scorer plug and still same problems.. When lane 11 is off it is fine, but when 11 is on lane 12 will either score an F all the time or you will get a few scores and a few F's anyone have any ideas they would be greatly appreciated

    sounds to me you have a shorted wire or pinched wire could be in underlane i had this same problem a few months back and narrowed it down to pinched wire even thou the foul unit is off the wires will still send signal if they short .
    im never wrong just askme

      sorry for late reply thanks for the help, we found 2 wires in a connector had been striped and were touching causing the F somehow

      thanks again
