AT+E - seltsames Verhalten der Motoren

Is it possible that if windi has the wiring written here, and I've wired it the same way as him so it might not work for me?
Yeah, I think so, I had three Worx Mower here in same generation but three different motors inside, color and wiring.
Is it possible that I wired the wrong flat grey cable that goes from the driver board to the bldc 8015?
Maybe you should try to get run the motors without PCB first. Do you have a workshop power supply?
 
Yes, I power from an external source, not through a battery.

I read such a connection in the post above, but I'm not quite sure how to wire it up.
