    So motor does not run unless you jump solenoid? I would start by test signal wire at solenoid. Then double and triple check your solenoid connections. Can you post pic of solenoid?

    No,if you push controller button and it sends power to trigger the solenoid the controller is good.Supply 12 vollts to the little trigger wire to solenoid and see if the motor runs.If not it sounds like solenoid,

    black/white is a grond from neg side of battery to fender well and solonoid mounted over it ... it was the way it was the orange /black goes to controller

    So your getting NO SIGNAL from the controller to the solenoid.
    One little pin needs to be grounded and the other pin is signal power from the controller.

    And clean up that rusty nasty ground!

    Start be getting rid of that red jumper wire. Hook your orange/black where the red was and retry. Let us know what happens.
