Testing a brushless esc

[Wooders28]

I have a muchmore fleta pro esc, which I raced on wed night, stopped, removed the lipo and charged it again. Now the lights come on the esc, but no motor movement , no humming noise , nothing.

I've tried the motor with another esc, it runs , and another sensor cable , I've tried another motor on the esc, even a different reciever. I've the power leads sized so only the pos will reach the pos etc, is it possible to damage a mosfet without doing anything wrong? 

How do you test the phases? Voltage between A and B etc?

I have no idea but its interesting to see what people say.  I have seen on the NZ racing forum people asking about getting ESC's repaired and basically they are now throw away items unfortunately.  You got this one secondhand didn't you?  So it could have just died of old age or previous abuse?

Have you tried tasting the wires?. If they taste fizzy, its working fine. Lol 

Its not dead till it puffs the magic smoke. Or goes bang. 

Dodgy switch?.  Sorry cant help more than that. Gotta be loose connection somewhere?.

Yeah, it was second hand, but like to think it would go pop (like the max pro did) or at least a bit of magic smoke , but no, fan running, no smell and lights flashing as they should!
