Battery checked and connected to trolley all 3 coloured lights come on when you turn speed switch a click is heard from controller but no movement Motor checked with spare battery and runs normal. Any advice please. Controller?
Although the controller clicks it may not be working. Regards the handle circuit, I would think if it is showing and seems to be scrolling up and down the speeds etc. then it is working fine. The display normally corrupts in some way if it is faulty. After checking all the connections to and from the controller to the motor then this would suggest it is the controller box under the battery tray which is not working.
