Hi all,
I could use some help or suggestions with my BBS02: this is a 48V unit with a 850c display, no throttle, PAS, no brake sensors.
The unit failed a few weeks ago with those symptoms:
- walk mode works normally: the motor moves the bike forward, walking speed, no strange noises
- however nothing happens when pedaling, the motor never starts; the display shows 0W
- there is no error code of any kind in the 850c
- the speed sensor is properly connected, and the correct speed shows on the display
- I had reprogrammed the controller but simply to lower all the parameters; and with the new controller I tried both factory settings and my settings and the problem is the same in both cases.
I have replaced the controller with a compatible aftermarket controller, the problem remains. I have double-checked the black and the white connectors (PAS and
hall) inside controller and they look fine.
I haven taken apart the motor side of the bbs02, is there anything I should look for if I do that?
Any suggestions welcome, I would hate to replace rotor and stator to discover that I missed something obvious!
Thanks,
Franck
