I have the identical problem another posted described with this machine SN KH422829. Have power at the convenience plugs but no weld power. I will begin trouble shooting next week as the tech manual and experts on here have suggested. The previous owner told me he did "jump start" the welder a few times. From reading, I think that is the death move for these machines. The main reason for this new thread is I'm wondering what everybody does with their bad PC2 and other boards? I was an electronic technician in my working life and I might be able to fix a board by troubleshooting down to a component. I'll post my progress when I get started. Thanks in advance.
No announcement yet.
Another busted Trailblazer 251 with only 290 hours! Anybody have bad PC2 boards?
