    Is it bad its the one tied to fine adjust.
    I undid band and cleaned the rust still no go.
    Is spot where its coroded able to cause it to not work.

    Would this cause the need for a reflash?

    I just about cant work on the thing with most everything agaist cab of tge truck.
    Visually it looks like s1 and s2 still have all theyre cables attached.

    I guess its gona have to come off the truck grrrr.

    Thanks alot everyone.

    That part is a resistor # 030060 , 375 watt 20 ohm, At miller4less is $51.83

    Look on miller website with your serial#

    Test it, look on internet on how to test

    You are awesome. I had never head of miller4less

    Im getting 12ohm reading through the 20ohm resistor. I thought it would be broken but its not

    Local norco has a 50ohm resistor what would that do in place of the 20. Id also assume its only 225 or 250watt.

    Im getting a reading of 12 but dont know what that means meter is on resistance my first that to was it was,12volts.

    So it is has 12 ohms and does have any where from 75- 180volts in it. It is nroken at ate out spot. I moved the strap inside the broken spot.

    I think its just not doing what it does 8m not sure if it has anything to do with it igciting? Assuming it must.

    Since it is bad ill replace it. I can with it on the truck

    I did see each sqiggle on corncob is worth about .5 ohms its 12 where fine adjust band is.

    Thanks for the info between my gibberish and not understanding electricity im sure im a joy to help.
