HELP - Bafang Rear wheel not turning after inner tube change ??

[bilabonic]

Third time of asking: Is there a connector about 12" from the motor?

Sorry Dave, no it's just a standard Bafang.

 

[bilabonic]

do you know how to test the Hall sensors?

No, but i presume theres a field voltage and a pule return of some sort.

May help if you get some pictures up of all the connectors.

Hi Mate,

It's such a simple set-up, i only have power, hall sensor, throttle and brake.....

What pic would help ??

Of all connectors, both on the controller and motor.

We can start from there.

Standard Bafangs have a connector about 12" from the motor!

You have all the symptoms of a damaged motor lead. Probably a hall signal wire is broken inside the insulation. You need to measure the voltage between the black and each of the three signal wires while you turn the wheel slowly backwards. You should see the voltage switch on and off to 5v when you turn the wheel.

The controller will sense the hall connection, so try to run with them. Did you try just leaving the hall connector unplugged so that the controller switches to sensorless mode, which should work unless the phase wires are damaged or the controller is faulty?
