Has anyone had to replace their TGE magnet and PAS sensor on their bike. I believe maybe mine has gotten rusted from the salt air and now the connection between the 2 is bad. I've tried sanding a little rust off and cleaning it with alcohol but still doesn't work. The red light on the sensor does light up sometimes and the bike will sometimes jerk like it wants to go, but it doesn't. Would any replacement 12 magnet and PAS sensor work? I don't have the paperwork for this bike so I believe I am unable to get any help or parts from AddMotor. Any help with this issue would be very appreciated. Thanks!
