Did I kill my MMM V2?

[pasan]

Welp I couldn't find a dispensable 30A fuse anywhere, so I went ahead with the circuit breaker. All seems fine on 12 cells, the BEC shows a solid 6V at the outputs, all three LEDS are flashing in unison and the fan refuses to switch off because the boot sequence isn't complete until the thingy detects an Rx. Castle Link also works, I did a fresh F/W update and reloaded my saved curves. Tomorrow I'll attempt at driving the car with 12 cells, and then try it with 3S if all goes well.
