We have Tongshengs fitted to two ICE trikes. My wife has failed after 1700 faultless miles. She recently set off but after two pedal strokes the motor cut out. It did this a few times and now won't function at all, there is no sound coming from it. I have checked everything I can, battery is good, display working as normal with no error codes showing. I've unplugged and replugged everything a few times, checked the speed sensor which is positioned correctly. I even tried it without the sensor fitted. I have taken the covers off and it's pristine inside, no evidence of water damage or any other noticeable fault.
I think I have searched every entry on the site plus Google but can find no information as to how to determine if it is the controller which may have failed. Does anyone know how to use a multimeter to test the terminals from the controller to the motor, which can be seen when the cover is removed. It would seem essential to be able to do this if the motor is to be repaired, otherwise it seems one would have to replace the display, controller, torque sensor and possibly the motor in turn before solving the problem. It would seem easier just to buy another complete unit and keep the old one for spares. Any help would be appreciated.
