    On my ultra-mount western plow the passenger light low beam is not working, but the high beam is and now that I have the plow removed, the passenger light low beam on the truck is not working, and again the high beam is on the truck, same as the plow. The plow is does not have the new nighthawk lights and the truck has the nicer halogen lights.

    Thanks for any help in advance,

    Start with checking the yellow wire in port 3 on the Iso with a test light with the low beams on.. does it have power?
