Hello Nice Forum site!

My dad just dropped off his trailblazer 302 welder for me to use. He bought in in 2005 and he only starts it up once in awhile and never uses it. Well we checked over everything before we tried to start it but the battery was dead.

I put it on a charger and let the battery charge up. When I started it everything was working good. I shut it off for a few minutes and started it again. This time I had no power at the outlets and nothing lights up on the panel. I Checked all of the breakers. Did on of the circuit boards go bad which one? Not sure what else to do?
