Hello,
I have a China bought E-bike. It's a fat tire style commuter.
Specs:
750 W
Bafang Motor
C901 Display
Problem:
As I turn on the system the display flashes the system is on and then within 1 second it goes to Err 30.
I have a similiar model e-bike and plugged in the working ESC controller and everythig works fine except the display LED modules.
I have traced it down to the Display giving a err 30 when I plug in the ESC controller that works.
Hub motor works, lights work, Pretty sure Pedal assist works.
Attached are a few pictures of the labeled wiring and the ESC controller.
I am looking for help in replacing the controller.
I found one and not sure it' works.... ebay rep said its not compatible.
Any help or suggestions is greatly apprecaited.
