    Hooked up plow on my 06, never had any issues before but now the iso module is just buzzing. Unfortunately, it did work for a min innitially and now the plow is stuck in the up position. ANY IDEAS??

    All fuses good, plugs are clean, no corrosion, yes everything is plugged in the right places on the module.....and whatever is going on it is not allowing me to operate my fish stick at all (does not power on but is back lit)

    Am going out now to try another plow on the truck

    THANK YOU in advance!

    Try swapping controllers if possible.

    I did, fish stik didn't work so i tried my spare joystick and it did nothing in the up/left/right movements and only buzzed when i hit down.

    Thank you for the quick reply!

    What is buzzing ? Check the relay. is it energizing? Is there power to the motor ?

    The iso module is what is buzzing.....no power is getting to the relay because something is stopping controller power/signal from getting there. I would try another iso module but if i somehow fried this one i certainly don't want to fry another one

    bad ground somewhere. unplug the iso first. disconnect battery leads to the plow at the battery. clean, grease and hook back up. is the black/orange wire on the negative?

    plug it back in and try again. still buzzing?

    A buzzing Iso is usually due to a weak 12V or ground signal Mike. Be sure to check the red switched ignition wire for good continuity, check it right at the Iso plug if you want. Plug 1 pin C.

    Double check the small black/orange from the neg battery terminal as well for a good ground flow. Check it at port #2 pin C on the Iso plug.

    Make sure the 11 pin grill plug is in perfect condition too as the black/orange goes out through it and right back in to supply ground to the entire system.

    Going out now to start on those diagnostics, one question, do you mean the switched iginition wire that goes into the controller harness in the cab?

    I'll report back soon with findings.

    It was the 12v power wire going into the control harness! It was only getting 3.6v, moved it to the RR WPR fuse which my truck obviously doesn't use. Awesome! THANK YOU B&B

    Ken, i appreciate your hospitality greatly! Networking in an area is very important to me and this is one of the reasons, thank you very much for offering the solenoid! We should meet up and get lunch sometime.

    I must say, through this i realized the importance of having a second truck. I can do my route REAL tight with just one truck but would rather be using two during a storm. I think the only thing that kept me calm was the fact that i had another truck that could be used at a moments notice!

    Thank you guys again for all your help! It is very much appreciated as always!! I am looking forward now to being able to plow the first storm in my Dmax!!!!

    Good to hear it was an easy find Mike. It's those last minute scares that will really get your blood moving.

    And you're welcome, but you already knew that. :salute:
