bike conversion kit help

Q:I bought the 1000 W bike conversion kit 8 years ago in your company. Today the hub motor broke. Initially there was some creak in the motor at a high current. Then unexpectedly the motor had slowed down with strong vibration. Now the throttle does not work and the motor rotates hardly.
Could you help me?

A:Please check three pairs of motor and controller.(Heavy Yellow,green and blue)
When you ride,only one wire loose,it will be strong vibration.
Generally the controller is broken.
Remove motor wires from controller.Make three wires(yellow,blue and green)NOT touch together.Use you hand to rotate motor easy.If need more info,please visit https://www.leafbike.com/ site.

Q:I found the fault. It was due to a short circuit between two phase wires in the area of them connections. I made too weak isolation.
Thanks a lot, Peter!
