Bafang M510 help needed

[Mark From Scotland]

Morning, my Vitus powered by a Bafang M510 just will not start.
I bought a BESST tool, a new controller, new wiring loom and a new head unit.
Both head units turn on when connected to the BESST, but not when the BESST is disconnected.
All replaced and still shag all.
Any thoughts or help?

Maybe after a long time you will have solved it, but probably your problem is the internal wiring of the motor.
Disconnect the controller connectors and use plenty of deoxidizer.
Usually the fault is the VCC PIN.
