What are the chances that I have bought two bad controllers?
Hello

I am bench testing my new controller Model KT36/48ZWSRM-NBP03 and I can not get power to the motor

I have a freshly charged battery. 48V 12 amp. I do have power to the controller
I have the Power Plugged in RED BLACK to the battery properly
I have the Throttle hooked up to the controller Black Red Blue
MOTOR:
I have the Motor Hall large white "six lead" plug Black/White Red/Yellow/Green/Blue
I have all 3 stages wires plugged in Yellow Green Blue

I do not have the PAS plugged in
I do not have the 2 sets of Brake wires plugged in
I do not have the Instrument wires plugged in

I turn on my battery - I twist the throttle - the motor does not turn

I DO have an EBike Tester as you can see in the picture...
The throttle tests OK
The Motor tests ok in all stages as I turn the wheel.

When I plug the ebike tester to the controller ... and turn on the tester and battery, I do not get the 5v lighting up. And when I turn the throttle- nada

What is wrong? Do I need the PAS , Brake Wires / and Instrument plugged in for the motor to engage and turn?

Can't see a picture, something must have gone wrong.

I can't find your exact controller But..
one thing I can think of is that your Controller needs a LCD to turn on, or It might have a red ignition wire which you need to apply the full B+ 48V to.


Anyways, until you link us from where you bought the controller or fix the image, then there is not much else we can do.
