I have been too busy to have another go but whatever I tried I couldn't get 5V and a solid red light. If it is flashing when pedalling backwards then I would try turning the sensor round so that it picks up from the other side of the sensor first? (e.g. turn it upside down if possible).

Numpty alert. Sorry, still failing.. My steps Plugged pas into correct controller wire from battery. Cut pas wire in half and exposed ca le both sides. Measured voltage of wire pairs as earlier from controller end (other end of cable no longer attached to anything. Twizzle controller end to...

OK, I am trying but pretty poor from my end to be honest. I have left the julet to the controller and then cut halfway through the pas sensor wire assuming I could just rewire that half way along to change them round? Using a voltmeter at controller end I get. Red and blue 5v Red and black...

Am I going to have to cut off the julet connector at the controller (battery) end to test the wiring (julet female connectors are too small to volt test. I'm trying to avoid modifying the expensive hard to replace parts :)

I have looked inside the pas sensor. Attached is a photo showing the new sensor (left) and original (right) provided by BMSBattery but which has never been tested. It connects to a BMSBattery 08 case with built in sinewave controller (do I need to take that apart?). The wires look pretty thin...

How do I do that? Won't this involve damaging both ends? It is like this.. https://m.aliexpress.com/item/4000112370687.html

Update.. Whilst I was away I ordered some sensors. I have received both a red one that usually goes between the bottom bracket and frame on a thin metal circular mount and also a KT-D12L. I wanted to use the KTD12L as I could stick it to the frame but for some reason it isn't working. When I...

Presumably you could just replace them with leaner crank arms? (Though I wouldn't have a clue how to determine which would work).

Thank you. I have asked somebody to take a pic for me :) Sorry for the baby questions but I am assuming 118 will be too small (just 2.5mm, with 1.5mm taken up by the sensor holder). It is a shame that it knocks out both sides equally but I guess Shimano have bigger concerns than PAS.

Thanks all. I am currently away with work and haven't been home for the photos. However, after further reading, I was wondering if I can simply replace the bottom bracket and put it on the left hand side. The current BB is BB-UN26 and according to the specs is 113 spindle length. I probably...

Hi all, I have recently taken ownership of a rear hub system and cannot wait to get started. The system doesn't have the PAS ring / sensor so I need to buy one and have been working out the best way to do this. My bike has a Claris 50/34T chainring and I was all set to buy this...
