Bafang BBS02 – Intermittent Cut Out

[JohnnyBBadd]

Hi

I wonder if anyone can advise regarding the following fault with my BBS02. I have intermittent power supply to the motor. The battery connections are fine as the LCD stays on at all times, as does the small red light in the speed sensor. I've done all the ‘wiggling’ of wires and unplugged & re-plugged to see if it is a faulty loom, or connection, but this doesn’t seem to make any difference.

Any ideas?

Unplug both brake cut-offs and see if problem persists. Be careful when testing though!

Any fault codes on the display?

I don't have the brake cutoffs connected - I like to live on the edge! (and get through loads of brake pads)

No, nothing - the display is all good.

Lol. Even though you are seeing the speed sensor showing a red light, make sure the magnet is not too far from the sensor, or at an angle.

I have exactly the same problem with mine. I think it is the controller ......again

Controllers can't really go intermittent. More likely a connector issue in the controller compartment.
