Hi. I have an ebike with this controller and this pas.
I have tested the motor with another controller. no problemo. i used this battery too.
so the problem must be in the display, controller or pas. I suspect pas because i inspected it and the red wire was severed. I soldered it back.

how does one troubleshoot and fix a pas and controller?

some pictures follow.

also I want to add a throttle to the controller. I have an st link but wouldn know how to use it.
even just getting the pas to work is fine.
if there are other features on the controller I am happy. please help me identify what features my controller has, add a throttle and fix my pas.


I must say that the spring that holds the mosfets in place is a pain.

I realise i posted in the wrong one and should have posten in troubleshoot, maybe. how doeson move a post?
