    Hi all
    First post but i've been lurking for a long time now. I finally bit the bullet and bought a new blizzard 8000hd friday from local dealer. Decided to do the install myself (not my first plow install).
    So after running all wiring double checking every conection heres my problems.
    1: hand held controller wont turn on
    2: have power to plow but nothing works
    I called the dealer gave them the run down. After getting no where with them I unhooked everything off the truck then rehooked it all back up this time layed on top the engine so nothing was hid, bent, pinched etc.. still power to the plow but nothing works and controller wont turn on.
    Yes all fuses are good checked with meter
    Yes I have power to the plow the main feed wire thats it
    any ideas would be great

    Where did you connect the ground? If it's not right to the battery that's where I'd start.

    ground is straight to the battery. I've got the entire harness laid out in garage hooked to a stand alone battery and still nothing.Im leaning towards I have a new bad module only thing in the system i cant check with a meter.

    Have you confirmed power at the small red power wire in the control harness? (the one near where the controller plugs in)

    If that's good, check the two 4-wire weather pack plugs in the control harness. One plugs into the lighting harness, and the other plugs into the truck side battery cable. The one at the dead end of the control harness goes to the battery cable, and the one that's broken out of the harness at it's mid-point goes to the lighting harness... they can't be swapped, or you'll have no power to the module or controller.

    yes all plugs are correct I put a jumper straight to the battery for the red wire at the controller and still nothing. The only thing that does work when i hook the plow to my truck is the lights.

    If you're certain the two plugs in the control harness are plugged into their correct locations, then check the controller fuse. It's located in a dual fuse holder which is broken out of the lighting harness near where it plugs into the "B" & "C" positions on the iso module. There's two ten amp fuses in it. One is for the parking lamps/turn signals, and the other is the controller fuse.

    Five fuses? :confused:

    Just to confirm... This is a new, two plug plow, with a multiplex system and a three port isolation module?

    Only two plugs going to the plow? Correct?

    Use a test light instead. Are you trying the plow with it hooked up and plugged in?

    Right, I assumed afterward that you were including the fuses on the plow itself.

    What dieselss is saying is that you have the plow plugged into the truckside harnesses when you're doing your testing? Without the plow connected to the truck, you'll have no control power.

    I have both plugs plugged into the plow while testing. I did notice last night without the plow plugged into the truck my truck lights are screwed low beam is fine when I switch to high both low and high are on. Now I did just tare the front of truck back apart again to confirm light harness is correct per the book instructions and it's good.

    Hook the entire plow up and see what happens. I'm sure you buggered up somewhere. Where are you located?

    You're talking on the truck itself? That's the way it's supposed to be on that truck. Both low, and both high are on when the high beams are on.

    Ok after moving the plow with the tractor I bent one of the kick stands so got the BFH after straightening the kick stand i plugged the plow back into the truck and magicly everything works.:dizzy: I guess now the search is on for what I shook by beating on the kick stand.
    Thank you everyone for your thoughts and comments there's nothing worst then having a brand new never used broken piece of equipment.
