    Well I've got a stumper....right ramp diverter only buzzes or slightly opens, check in solenoid tests same thing, when I ground coil it works perfect so can't be mechanical, traced wire to power board and ground pin and it works perfect so can't be wiring from board to coil...figured maybe transistor so replaced that on power board same issue....any thoughts?? thx in advance

    Coil stop or rubber grommet there and not worn ? If the plunger rides to low in the coil you don't get a full whack.

    When you ground the transistor, it's getting more power.

    I wouldn't rule out ribbon cable between CPU and driver board.

    It doesn't happen often but consider the possibility of a weak coil.

    My divertor would just sit the and hum every 5th or so activation. I checked coil solder connections, reseated ribbon cables and board power/grounds. Also checked resistance of the coil vs a new one which were the same. Eventually put the new coil in as a hopefully last ditch effort and it's been working great since. I put the old coil in another machine's knocker and it just hummed when activated.

    reflowed the solder at the j130 and boom, problem solved, thx all!!
