As part of a build of a new Cycles Maximus rickshaw we are using a Bafang front drive hub used in conjunction with a transaxle to transmit drive. The issue we are having is the kit supplied had the wrong plug on the pedal sensor so after belling out the wires to make the appropriate connections we find that we cannot get the sensor LED to flash when turning the cranks - it only has a continuous illumination and nothing changes when we backpedal. Can anyone shed any light on this?.

The PAS sensor LED is permanently illuminated because it is being backfed a voltage through the signal wire. As Neal states, either you have the 5V & signal wires connected the wrong way round, or there is a short between them somewhere.

I have tried several wire sequences all without success. There is no possibility of a short circuit unless it is in the controller itself. Thanks for the replies.
Or possibly a short inside the sensor. Have you continuity tested the 5V and signal PAS sensor wires?
No I've not continuity tested those wires but will do, however, i have tried another sensor without any luck which leads me to the controller..
Get yourself the cheapest 5 magnet pedal sensor. They're the most reliable and most compatible sensors. I don't why people bother with these fancy ones that are nothing but trouble.
If you show us exactly what you have, it would be easier to diagnose your problem. we've got no idea what you've got nor what you've done.
