I have 3 ebikes. On two of them I had to change the order of the wires on the throttle control to get the wheel to turn. The red throttle wire had to be changed to the green connector wire. The green throttle wire to the black. The black throttle wire to, you guessed it, to the red connector wire. The connector them plugs into the controller connector. I must have done something wrong here. I can't get any factory wired throttle to work on either bike, and i have tried several. Anyone have any ideas?
