  • A "fried fuse" isn't always visible. Also, how do you know the MOSFETs are fine? I'm curious as to how you tested.

    As for the caps you've circled as shorted: I'm guessing you tested in-circuit, right? Those aren't all shorts. (You may already know this, but I don't want to presume knowledge.) If you pull them off the board and test most if not all will be fine. You're reading the same short over and over, because pretty much all those capacitors you circled are wired in parallel with one end tied to ground. So not much info there, unfortunately.

    The chokes...

  • In-circuit it reads as 290nF. Can't pull one off a board right now, unfortunately.

    I've got one for you as well -- same board, the cap between F5402 and the drive connector, any idea the value of that one? The similar cap by F5401 reads around 470uF in-circuit, which of course can't be right, but I don't want to start pulling arbitrary 0201s off this thing just yet.
