Help with Miller Spectrum 375

[fasted1500]

Hello all, I recently acquired an older miller 375 spectrum and need help diagnosing an issue I have. When powered up I get the temp light warning. I opened up the torch and made sure all the wires look good and they had continuity back to the unit. Any help is greatly appreciated. Thanks

Thats a tough one but not likely an issue with the torch. I would open the power supply and have a thorough inspection of all the boards and and look for anything fried or damaged first.

I took a peek and nothing obvious is showing.
