Chasing a ground fault for 4 days, it was a cracked solder joint all along
Had a power supply come in last Tuesday that kept tripping the breaker under load. I checked caps, diodes, the transformer, even swapped the main IC before I finally took a magnifier to the board and saw a hairline crack around a solder pad. Took me 4 evenings to find something that took 10 minutes to fix. Anyone else ever spend hours on a fault that ends up being mechanical, not electrical?

Ugh, been there. Four days for a broken solder joint is rough, but at least you found it before you started pulling your hair out.

Four days of probing every circuit and @xena_jackson knows the feeling, one bad joint hides like it owns the place.
