    I need help again! lol

    I'm building a 4-way plow for a Friends Suzuki Side Kick. We purchased a 6' ATV plow blade , fabricated a lift frame and push plates. We also purchased a brand new Fenner hydraulic Pump off e-bay, it came with a control and wiring diagram , but I can't seem to get it to work according to the diagram.

    Fenner Fluid Power pump model # 1787*AC, with a Heavy Duty DC-80 rocker switch snow plow controller.

    There are seven wires from the controller:
    1) orange 12V from keyed power source
    2) black, Ground
    3) Red, right angle solenoid
    4) grey , down release valve
    5) green, left angle solenoid
    6) Brown, Starter solenoid
    7) Blue , Starter solenoid ( same terminal as brown wire #6)

    The plow will lift , angle right and drop properly, but it wont angle left, it clicks the angle solenoid valve but won't engage the starter solenoid, if I put a jumper across to the starter solenoid from the angle solenoid it will power up the pump and angle left, it also lifts the lift cylinder.

    Any ideas or suggestions?

    Anyone got a wiring diagram?

    How about any contact info for fenner Rockford, Illinois?

    sounds like you may have a defective selenoid coil, try swapping the left and right coils and see if the problem changes sides. Good luck, Roy

    It sounds like a jumper wire at the switch has come off or a bad switch.

    All Set!


    It was suggested that a jumper circuit was probably the culprit, it was! I found a loose solder joint on the jumper circuit, so I re soldered it and it works as a charm.

    B&B I did not contact SPX, but I do have a web address, so If I need to contact them in the future I'll know where to go.

    Thanks everyone for all your help and suggestions!
