Kiwi v2 lightning damage [fixed]
So it happened again. After an energetic cloud-cloud strike, I found one of the kiwis powered off and it didn't turn on again.
It turned out Q301 failed, creating a short to ground. After bypassing* it, the kiwi works again.
*) I blew it open with a 5V 10A power supply. Conveniently it is now open to ground but conducting D-S.

Wow. Q301 is supposed to give reverse polarity protection. But not be a fuse, lol.
