Advice needed - possible ESC failure

[wingers]

Tonight my motor suddenly cut out during a heat but when I tried a different motor it still didn't work, so I think the problem is with the ESC.

I haven't checked this before but one of the ESC phases is now connected to ground. I'm guessing that it shouldn't be.
Can anyone confirm that?

I don't know what the next step is but unless it's repairable I'm expecting to need a new ESC.
