    Take a screwdriver and touch the metal to both top posts of the solenoid at once. If the plow moves, replace the solenoid.

    Would the solenoid make the headlamps to go out also?

    I don't know.... Never had a fisher. Something to try, though. Check your fuses too. Just follow your wires from the plow back to the controller and the solenoid should be there somewhere, probably in the engine compartment.

    With everything being out I would think you may have bad connections at the grille plugs, try working them a little and have someone operate the controller as you wiggle the plugs together and see if you get any movement. If nothing happens get a test light out and see where your power stops. Do you have power to your controller?

    The motor relay is the solenoid you should have constant power to one side from a cable coming from the pos. side of your battery, then when your controller is used to get a plow function you should have power to the other side of the relay (solenoid), this power goes directly to your pump motor so you should have power there also when the controller is used , check those points for power and see what you have.

    Also you should hear a clicking sound from your solenoid when the controller asks for a plow function.

    I checked those and there is no power on the pump or the connection but at the relay the two red post have power. I think it is that because the whole plow died. And after I I tried to move the joystick I heard clicking. Not the glow plugs. Then it never clicked again I think I fried it

    the 11 pin harness controls headlights, and has ground in it that completes the connection if you lose that it will kill the entire plow.

    the relay will have power its hooke to the battery, the main harness tells the relay to send power (by way of the trigger wire, little wire on relay) to the motor. when you lose that ground the plow is essentially dead. so it wont trigger relay to send power to plow

    Jay he say's he has power to his controller so that ground circuit must be complete. I'm not sure what he means by power to two red post though, zrain jump the two main connections on the relay and see if that moves your plow.
