Oh I looked very closely for hours and didn't find any burn marks, and I don't recall seeing any smoke when it happened. when I turn on the supply I still get the bump. and if I watch the output voltage that bumps also. I tested the resistor that is attached to the green wire, it still holds an ohm value. then it goes into a IC circuit, maybe I should try to replace that chip. some time in the future, I want this nightmare to be over.
