I've checked a bunch of things. I do get the relay clicking when the foot pedal is depressed, but no output. Switched to panel still no output.Circuit boards don't look burned, no lose wires, power to transformers and still no output. I've studied the schematic and it seems like the thyristors are in the path after the transformer. Now I'm not an electrical engineer and I've heard that thyristors are kinda like fusable links, but It's really beyond me why it won't work anymore. I guess I'm stuck with my ac buzz box and my mig welder again, bummer. Scrap is high now...
