        If you mean when I was testing with the variable PSU, I don't remember exactly, as I didn't document it. I do remember that we took it fairly high, I believe as high as it could go. I'd hazard a guess at 2-2.5 amps? If this doesn't sound right I can always go back and double check

        Thanks!

          Use thick wires to provide power, solder + wire and - wire to board. 2A is not enough. Starting from 5A you might feel something if the short is near big power planes or some bigger controller.

              I got it!! I finally got my own bench PSU, so I was able to work on it at my leisure. I don't know how I missed the problem component getting so hot! It was C4690

              Thank you so much, everyone, for your help and advice, it helped me out so much, and I learned a lot!
