Thank you very much, really informative!

P4 connector - 3.7 ohm with CPU, 8.8 kohm w/o.

output caps-same.
No short between coils and gnd, so I think it's high side.

So, when I remove shorted one, I should measure few kiloohms on P4 with CPU in?

Furthermore, I tried powering board on w/o P4. No signs of life (I believe PSU should start, right?)
stay classy
