It seems you can run without an LCD if you first program the controller using an LCD.
So you cannot run without an LCD if you have not programmed the controller
to run without an LCD. And you can only do that if you have a controller
when you do the programming.
I got a question about some cables coming out of this controller:
A bike I an trying to repair apparently has a bricked controller after an owner
connected the female connector to one of the matching male connectors shown,
assuming they were related to speed control.
Are these...
