in the meanwhile i checked original AO4413 again and it turns out that it's ok - not damaged. Ill solder it back in and then check resistances

to be precise, i replaced it with equivalent because i couldn't reach 4413, i put there AO4423 which should be ok, but as i said - it didn't make difference. As you can see in the picture - orientation is right - both mosfets are connected on their drain sides.
As for resistance: it shows stable 391k on drain side, but on the source side it varies very much. First time i touched it - it has shown values from 20k and rising, checked again - start at 30k and going down. I waited a few seconds and checked again - from 10k and rising. While i was...
