Hi,

Macbook, side on 1 cm water on bag. Only USB-C side- Magsafe was on water. IT-Shop clean the board, board looks ok.

JE700 - port USB-C - nothing, USB-C multimeter stay black
JE700 - port USB-C - nothing, USB-C multimeter - 20V - 0.1 amp

I have ppvbususbc diode mode .147, does that point to bad UF400 ?

You've mentioned JE700 two times...

Compare diode mode readings between all ports.

Hi again, bad luck, Mac is no longer booting. It was booting, I would turn it off. I did that process twice and I waited for customer and now it's no longer booting. USB-C is on JE701, it stay at 5V and 0.17 amp. UF350 that manage JE701 looks ok, so it's no same issue. I've cleaned again the board where I removed UF300 but it doesn't help.
