Hey sorry to be such a beginner here but what exactly do you mean by ‘jumped red and yellow’? Does that mean you put a pin or ‘jumper’ in the yellow slot that connects directly to the red wire slot? I’m having all the same issues and have all but thought I am insane. These dookie brainpower controllers are a hoax. I have the exact same setup and one of the s866 lcd gives me an error 10 and the next 07 and that one runs with throttle. Then another gives me nothing and lastly a fourth gives me error 00. Literally same controller and exact same setup but only difference is the lcd that came with each controller (all s866). Grrrrr
if you could clarify what you did by jumping the red and yellow I would appreciate that so I can continue to work through this madness.
