This one has me befuddled.
Skar RP2000.1 came in with 2 blown n640s on the output side. Pulled all output fets and cleaned up the board. Went to fire up to check for rail voltage and for some strange reason im getting high rail on the low side drains which of course shuts the amp down entirely.
Where would high voltage rail even come close to the low side drains to make a component fail?

The really curious part is that the DMM shows no continuity (audible beep) to high side rail at the rectifier. When setting the DMM to auto ranging resistance it slowly works its way to 1500ohms.
I need 50 lashes from a cat of 9 tails.
I found a very weak solder bridge between the drain and source pin on the high side output....lol
8x magnifying glass and a REALLY bright light saved me there!
