    Re: Miller Big 40 won't weld no AC

    Hi again I finally got the rectifiers but is not doing any good, Tried to flash again and can make a grinder run slow as long as I have the 12v hooked to #5 and #6 but as soon as I take them away it quits so I am lost at this point. Sure would appreciate any other ideas. Sorry for taking so long but there was a mistake on the order for rectifiers and took longer. Thanks alot

    Thanks the sn is HJ 198309 But I think someone may have changed the front panel as some of the wires do not match so I used a manual from about a year earlier which is the hh series. The manual is the 450d.

    Yes I am running it a weld rpm although I haven't checked the rpm I think it would be up close to what it should be.

    Re: Miller Big 40 won't weld no AC

    Ok just to let you know the rubber tip on the carb needle seat broke off this morning so right now it won't run till I can get one. This thing had been sitting along time is the reason that happened i'm sure. does any one know the right kit # for the zenith carb on this? Also Duane I got your manual on this but would like for you to explain where to get the voltage readings you are talking about as I just want to be sure I am doing it right. Thanks very much.

    Re: Miller Big 40 won't weld no AC

    Just an update on this I got this to running again and did more testing only to find that I that I that a ohms check from wires 50 to 51 shows open and have checked them down to where they connect to stator and are ok to there so I assume I am looking at a bad stator although as I had said at the first of the thread I checked then and they showed ok so I am not sure what's happened but that's what it shows now. Any ideas appreciated. Thanks
