My right side PAS broke and I had to get a new one. Ended up buying two new PAS with magnet disks from two different online shops, still waiting on the "correct" right hand KT-D12R to arrive. In the mean time the supposed right hand PAS arrived and after shortening the cable and fitting female JST connector supplied by the shop, I was finally able to test the PAS. Here is the link to the PAS page on shop website: https://www.rat-holland.nl/Onderdelen/Overige/P.A.S.-sensor-set-deelbaar.
Well it turns out the PAS worked correctly - but only pedaling backwards. It is obvious that the PAS is for the left hand side since flipping the magnet disk does not change anything, PAS only senses rotation in certain direction. Now I tried flipping the PAS itself and I can get it to sense the correct rotation but just barely and I had to remove the part that allows it to attach to the frame. So now I know that the PAS is for the left hand side but ...
Is it possible then to simply flip the sensor by flipping the PCB? Meaning, if I open up the sensor, remove the potting, extract the PCB then simply flip it 180 degrees, will it work reliably? I do not know the layout of the PCB and the hall sensors and whether simply flipping the PCB will be enough to allow for correct and repeatable signaling. Does anyone know if this will work? This sensor was labelled as "King Meter" and on the disk it says SNH2. I figured out this is the King Meter SSP-DH sensor and it is definitely left hand sensor.
I would appreciate it if anyone can confirm this will work before I remove the potting. Currently the sensor works perfectly for left side and I don't want to destroy it or damage it unless I am sure it will work on the right side. The other sensor that will arrive is definitely for the right side so I am sure it will work but I would like to have a backup so I would modify this one if it is possible. Thanks ahead of time.
