  • Welder repair Help!

    We have a Trailblazer 301D that will not start. We have had the starter checked and replaced the ignition switch. Nothing so far has helped. Any suggestions would be welcome!

      "Will not start" is insufficient information.

        Nothing happens--not a click, no lights, won't even try.

          Sounds like a bad connection someplace. Ground? maybe. Battery good?....Bob

            Now THAT's useful info that should have been in the first post. Now we can ask good questions.

            Battery voltage?

            Do you have this voltage present at the ignition switch? Who replaced the ignition switch and why? Who "checked out" the starter and how did they do so?

            MANY threads here, as you can imagine, are about "welder repair help." The subject line should be a SPECIFIC subject, including the model of the machine and the problem itself.

ID:	586509 Assuming this unit has a starter solenoid... what happens when you place battery voltage on the solenoid terminals?

                  Check the red wire in the harness plug from the switch to the engine. It corrodes in the plug.

                    You have a short. Could be the full bridge rectifier or a diode.

                      Does anyone have any information why a Miller blue star1e would run and weld for a few minutes and then the governor arm will hang wide open. Start running rough and die

                          It would be a good idea to start a new thread so people would know it was about your machine instead of having to read through six months worth of posts about another guys machine. You just sorta popped into the middle here.
