trying to help a buddy get his eBike back up and running... it is about 6 yr old, and just 'stopped working'. The display he had was PAS only, and I noticed the PAS sensor light was not blinking when pedal rotated, so I tried replacing just PAS sensor first. no go. So, I ordered new KT controller and matching LED display (PAS only, no throttle). The new controller came with lots more connectors that the old one, and different ends.... So I cut off the ones I needed to and spliced to match.
I now have everything looking good with PAS blinking when pedaling, but the motor never kicks in.
The other odd thing is that when I connect the motor sensor 5 wire to the controller 5 wire, the display shows low battery voltage and PAS sensor light dims. I disconnect, and battery shows full. Reading other threads, it sounds like the big motor phase wire colors may or may not match the new KT phase wires..... Would this POSSIBLY explain the behavior and the motor not 'kicking in' even though everything else is ok? If so, how do I determine the correct matching of the motor phase wires? Would I need to change the order of the 5pin sense wires as well?
or.... is it more likely that the wire harness itself is bad? I see only 3 fat pins in the motor-side connector, I dont see anything for the 5 sense wires at all coming from the motor ?!
so.... the question MAY be whether or not a KT controller that has both 3-pin phased power, and a 6-pin sensor connector will work with a motor that doesn't seem to have any 'live' sensor wires? The old controller did not have a 6-pin sensor connection at all... so are there two basic types of the controllers and NOT interchangable?
