Hi all,
I have a Ninebot ES1, one of the motor cables did a short with the body.
The control unit died
I got a cheap control unit, it worked for 15 mins then died
Now I'm wondering if the motor is damaging the control units.
Is there any way to check it ?
What if I connect the three power wire of the motor ?
Where can I find some wiring diagrams ?

Thanks in advance for your help
