Hey all I have a Speedpassion BL motor that I bought new. I was soldering the leads on when I bumped it off my work bench and it fell on the floor. I hooked it up to test it out and it sounded like carp and got warm right away under zero load.

I turned it off and spun the shaft. There wasn't any more or less resistance in the motor than the ones I have that work fine.

I believe the fall shorted out either the sensor or the stator. I was wondering how to test these components w/ a multimeter so I can tell which one is bad and fix it.

All help tips appreciated.
