    Gentlemen, thank you for your feedback and following along, I have learned something again here (you can always learn something new...) and I hope this helps someone else.

    I will update next after the new boards arrive.

    Cheers!

          Good morning. I know it has been a while, but I wanted to confirm that this was indeed the correct repair for this unit.

          Duaneb55, I agree with your assessment on the logic for disconnecting the battery when charging.

          Thank you again to all who jumped in and got involved! I do hope this helps others in the future!

          Cheers!

            I have a Miller welder 275 trailblazer it has been jump started many times it has an intermittent problem now where if it won't idle down it won't weld so after reading your forms I took your advice and change the circuit board and I still have the exact same problem any ideas

              Number one, start your own thread, you have a totally different welder.

              number two, call Miller tech support and have them walk you through trouble shooting your welder. Have the tin off and a multimeter handy.

                  I stopped jumping all new Trailblazers. I made a mistake with one that had a dead cell. We jumped it and pulled the cables after it started and fried both brand new boards. Now if a Trailblazer with a bad board comes in and won't crank it receives a new battery. Expensive lesson for sure and honestly we've jumped off hundreds of machines before without a hitch. Live and learn
