also here is a photo for it
That looks like a CT811B9 speed controller to me. Here is a link to The CT811B9 wiring directions: http://www.electricscooterparts.com/hookup/SPD-CT811B9.htm
thank you but mine has only 17 wires
my scooter wires are lost so i do not know what these connectors refer to?
also i tried to find this controller but what i found didn't match mine only LB33A was like it except for the wires colors & its positions
All thanks to you
you are really helpful
When i flip switch to turn on it just starts going full speed without touching throttle
it has this controller CT-811B9 Controller
That type of problem is usually caused by the speed controller however it could also be the throttle. I would disconnect the throttle from the controller and see if the motor still runs at full speed. If the motor runs at full speed with the throttle disconnected then the speed controller is faulty, and if the motor stops running at full speed with the throttle disconnected then the throttle is the problem.
