Title: Crack blowing fuse immediately [resolved]
Post by: Bhk1004 on November 01, 2020, 01:36:05 PM

All measurements up to powering it up at the end went well and were perfect. Cant find what's exactly wrong. Posting this up so someone can tell me where I screwed up. Symptom = plug in fuse poof.

Going to go reflow everything in the meantime.

Alright... think I reflowed everything and trimmed a little bit here and there. I'm down 3 fuses now so will wait till someone smarter than me saves me from myself.

The UF4007 between 21L and 18L is installed backwards. See page 39.
