Bafang G330 motor

[Aldesco]

Hi to all, looking for any advice on how to proceed. The motor, a Bafang G330 is not behaving itself but. I'd like to test the various components in the whole control chain.....in particular the torque sensor. This was replaced not too long ago so I'm struggling to believe it's gone again so really I'd like to do a bench test on this component so I know definitely if it's working or not.....that way I move on to the next component. Does anyone know how to test the torque sensor on these motors....can it be done with the motor in the frame still? Any help appreciated. Thanks
