    Bought a truck with a northman plow already on it. It works great except for it won't lower at all. Never had one of these any help would be appreciated.

    I have a northman plow and need a wiring diagram. Do you have a diagram?

    this happened to me last week, plow would not lower, I replaced the cartridge valve assembly and solenoid on the side of the pump(yellow wire goes to it). I'm not sure which one failed, might have been both, this fixed it, took five minutes, good luck

    Search this forum for wiring diagram, another user found a great owners manual which you can print out, many pages of troubleshooting are included
