    I was just plowing and it lost power and won't turn back on. Shut the truck off, checked connections, disconnected and reconnected. I'm sure it's something stupid. It has the fish's tickets controller. Loosing for a fuse now. Just thought I would hit you guys up to hopefully solve the problem quicker.

    If it's a three plug the isolation module under the hood has two fuses coming off port 1 of the isolation module.The 7.5 amp fuse is for the controller straight blade and 10 amp if you are running a v-plow.Also make sure the black wire with the orange strip that plugs from port 1 to 2 is plugged in and all connections on the solenoid are good and tight.

    It has 2 10amp under the hood and 2 locations on the plow with double 4 amp. All are fine. The ground on the battery was loose. Tightened that up. Still nothing. This thing is brand new. Same with the truck.I just disconnected everything. I wasn't even using it hard. Just moving the wings unDer some pressure and the controller lost power and won't come back.

    What about where the in cab power is hooked up? Like the under dash fuse panel, have you looked there yet?

    How about the connection at the solenoid? What is the red power wire attached to that powers the controller attached to? It should be key on

    The acc wire for the controller is hooked up under the stering wheel it's just a male female connection. Nothing labled. No fuses located under there. Just all makes connection locations with nothing labled. I pulled fuses in main panel under hood with nothing fried. All connections where hydrolic pump is located are all tight. I'm just clueless as to wtf happened

    So is that wire under the steering wheel have power? Did you test it? Are you sure it's not fused somewhere? Where it's hooked up to has to go somewhere, maybe that's fused.

    I check all fuses in dash. Nothing. When I take that acc wire on and off the point it makes the isolation module under the hood click. I don't have a power tester unfortunately.

    You just need a test, here's the wiring diagrams

    Is the controller lighting up. Does the red dot come on?

    Is this multiplex?

    This is obviously a Multiplex system, since you referred to four 4 amp fuses on the plow. Most situations which create a loss of communication to the plow, result in a flashing power light on the controller. If you're sure you have power at the controller plug where it attaches to the control harness, I'd check the single wire ground connector from the control harness to the lighting harness at port "A" on the isolation module. See page 3 here:

    http://library.westernplows.com/westernplows/pdffiles/29225.11_041514.pdf

    Otherwise, maybe try another known good controller. Like I said, most communication loss issues result in a flashing power light on the controller. If you don't have a power light at all, it's likely power or ground to the controller, or a controller malfunction.

    Also, check the four pin connector at the end of the control harness, where it pluigs into the truckside battery cable. I think you could have a connection issue there which would result in no power without a flashing controller light.

    All connections are good. I'll try the controller tomorrow. 50k paperweight over a controller. I'm not pleased.

    Try running a wire from the battery to the 12v controller diesel is taking about Just for giggles

    Back and running. The power feed was on a fused terminal on battery. They moved it and I'm back and running. Berlin chevy put it on. I can't believe they made such a simple mistake . Langs corner garage fixed my issue. Great guys over there. I tested that line and it didn't show volts at the plow connection. Now I know why.
