I have a miller blue star 6000. I started it up but its not putting out any power.

Depending on serial number, Miller started out with Kohler manual start, Kohler electric start, and then Tecumseh electric start. They ended the series with a Tecumseh OH160, miller part #070732. I have included the manual. https://www.millerwelds.com/files/owners-manuals/O424E_MIL.pdf

could be a faulty power control swotch
I am inclined that the voltage regulator the controls the amp out put is faulty
Take it in for a specialist diagnosis to a welder repair shop

Shorted rectifier (diodes) assembly. 2 flat pieces of aluminum. follow the weld leads back. I think it's on the left.

Miller switch part # 011611 you can order through your nearest Miller dealer.

The potentiometer for current control may be shorted, there may be an issue on the control board where the SCR's may be shorted. It is possible the accesory board was wired wrong.

It is also possible there is a broken wire in the current sense portion of the circuit, but I would first look the current control pot and at the SCR's to be at fault.

If you see a model that is close in description in the Blue Star models, such as a "145" the wiring diagram should be close if not the same. Otherwise select from the list the Blue Star with the same engine type as yours.

The If the tag is not damaged, and truly a JE series, you can download all the Blue Star manuals to find the one that has your serial number in the range. Miller is good with manuals, but sometimes the cross reference to just serial number does not work.

there is a dead short in the welder unit that is overloading the genset

wont run
