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?

it was working fine , just quit working , no clicking nothing solonoid is a f5794 k ..available on amazon but i bought at fisher dealr , oh yes plow lights work but parking lights come on when you step on the brake ,it

motor does run when you jump solonoid

So as kimber said, test light the power signal wire of the solenoid while pressing U,L,R,

 

[eraser]

got power there , only thing i think it can be now is the controller ........right?

 

[eraser]

controller lights up , but does nothing

 

[kimber750]

Need a pic of solenoid so we can see how you have it wired.

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,

ive put 2 solonoid in it both do same thing , i put second 1 in when someone else said that might be tht issue

I have a pic of solenoid in my phone but can figure out how to post

 

[eraser]

here is that pic

took a bit to figure out how to do it

That blk/wht is that coming from the controller?

And where is that org/blk going to?

 

[eraser]

answer

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

 

[dieselss]

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.

 

[eraser]

mm1

got rid of red jumper switched other wire , still nothing

 

[dieselss]

Did you fix that ground wire?
