OK, so the lights come on, but nothing happens? Was it working before? What is your gearing?

I had this happen with one of my MM escs. I had it way overgeared and I wasn't paying attention while it was cogging. I let it cog for a second too long. Fried the FETs. Lights would come on; I could plug it into the computer and program it, but nothing else. Now power to the motor.

Smell it. Does anything smell burnt?
