    I just mounted a used fisher minute mount straight blade. Everything went good except i have 1 low beam out on the plow. Hi beam works on both. Left low beam out. I checked the fuses, all good. 2003 silverado.Test light shows no power at the plug. I'll do an ohm test shortly and get back on.

    New bulb still will not work due to not get power to the plug. wire must be broken somewhere.

    According to the fisher schematic the black is low beam. white hi beam. That's not the case. Right side low beam is black. Hi beam is not white like schem. says. But on the left side, the hi beam is white. screwy. Now i went to a fisher plow dealer and he sold me a 3 port module. I also bought a wiring kit (29048) from him for the B and C port. Im wondering if I have the correct set up now. I believe this was originally a 4 port set up .Everything works perfect except the lights on the plow. The plow dealer manager told me he never uses the adapter (29047) in the kit. I had to use it or the plow lights dont work at all.

    If you've got a 3 port module system, check the reversible two position connectors on the left and right side harnesses... the ones with the A's and B's on them. They are specific to the headlight common... negative or positive. Sounds like you've got one reversed on the side that doesn't work.

    The only reversible connector i see is the one for the blinkers. Not sure what other connectors are reversible. But something sure does act reversed.

    Check out this pdf. It's from Western's site, but it's the same wiring as a Fisher. See page 10 for explanation on the reversible connectors..
