    The solinoid will not activate. Could bad isolation mod be the problem? I've tried 2 different controllers.

    Could be multiple things.
    Have you test lighted the signal wire going to the SOLENOID when you press U,L,R?

    One side is ground and other is the signal from the controller.

    Isolation module has nothing to do with coils. When the plow is plugged in a jump back wire activates the isolation module, which in turn, sends power to light up the controller. So... if the controller lights up then (other than the lights) the isolation module is out of the picture. So now moving on to the coil.... Assuming that this is a straight blade.... You have a six wire plug connecting your controller. Three of these wires go to the three coils to activate them. The coils are all connected to a common ground via a black / orange wire. The positive side of each coil has it's own wire connecting at the three pin grill plug and then on to the controller plug. Test for continuity on these three wires. They are light blue, light green and white / yellow. If you know which coil is failing you should focus on the wire that is connected to it. Of course it is important to verify that the coil itself is good. If you have an ohm meter just test between the two pin of the coil. There should be a few ohms resistance. You can also just connect 12 V across the pins of that coil with jumper wires. If the coil is good you will see a small spark when you disconnect the wire breaking the circuit.

    Thanks for all the help. Diesels, that wiring diagram was the ticket. I was not getting power to the solinoid that operates the motor. After testing the operation from the plug of the controller, it was determined that the brown/red wire that powers the solinoid had an open in it. Opened up the harness in the engine compartment and cut the wire and went directly to the solinoid and she started singing again.thanks again for all you help.
