Hi All, I have a 2000w--48V rear wheel conversion bike with a SW900 Controller. About 2 days ago the PAS started to flash and no matter what I try every time I turn it on it starts flashing. Any idea's out there. Many Thanks Paul

hi @A1Foxxy123 welcome, 'the PAS started to flash' do you mean the currently selected pas number on the display? Not something im using so ??
This first find from google lists error codes.. BUt nothing about flashing pas??

i would guess the magnet ring has slipped out of alignment and is perhaps not registering?? but its only a guess..

Hi, Yes the number is flashing. I will check the magnet this afternoon, and let you know.
Many Thanks
Paul

Hi, have just checked the magnet's and it's still flashing. I have just been told to hold the down button for 10 secs and see what happens. Wow all back to normal. Many Thanks Paul
