Please help!
Does anyone have photos of where each wire goes to the circuit board ..... #L9703-3? I have the wiring diagram but I have tried my best more than once and I believe they are correct !?!?!

I needed to replace the rectifier and in doing so, I needed to remove the circuit board. Part # L9703-3. I took lots of photos and even a video so I knew where the wires would go. Well after replacing the wires all I heard was a click when I pulled the trigger, so I had the board sent out and some circuits replaced. After reassembly, same result.

It's so bad, I'm thinking of buying a similar welder just to get the wiring correct then selling the new one...

PLEASE Help this new welder. I really don't like my stick 😒
