Can this issue with the controller, as pictured when it's burnt out, be fixed without replacing the entire controller?

Hey @Sc00tr you're correct, sorry about that I didn't have a picture yet as I had not taken it out. It's definitely burnt, here's a picture maybe you can give me your opinion on whether it can be repaired. (Soldering skills are a solid 2/10). It's where one of the phase connectors connects on the other side I believe. Not sure why it ended up happening as I was rolling on a flat surface.

I had 90% of charge on my scooter when I was breaking hard going downhill. After that the motor seems to be broken, it won't run anymore, and the front wheel don't rotate as easy as before. No errormessages or anything else that indicates that something is wrong. Anyone here who had this problem, or suggestions on how to fix it? I just contacted MI Store, waiting for heir reply.
So, for you who got this scooter, don't break running downhill

May I ask what break did you use? the brake from your handlebar or the foot brake?

I am mistaken, I thought this was discussing a ninebot es scooter for some reason, ignore my responseGeForceGTX wrote: ↑Thu Aug 15, 2019 10:47 pmbut wait, as far as i know, theres no foot brake in PRO version? because in my unit i have only handle break.
The mainboard will still turn on when it fries, shows mileage, etc. When you press the throttle though the scooter auto shuts off. I had the same experience, but I had a short in my motor wiring as I wasn't braking nor going downhill when mine let go (also really modded).tronixcity wrote: ↑Tue Jul 30, 2019 9:17 amHAd a customer just now.. his m365 pro motor is dead. mainboard is still turns on and all.. since I I do not have motor available for pro. he just replaced it with normal m365 motor.
longer range
cheers
I tried this when mine died, I'm pretty good at soldering and I verified my connections were solid and not touching where it shouldn't. Mine was cooked enough where I added little jumper wires as you can see. It changed nothing and I had to replace the controller. Clearly when this happens it burns another component on the board up. At that point not worth fixing.
Is your second picture your replacement board which you then reinforced with extra solder? What did you about the transparent epoxy coating on top of the board? Or is that the old one which you tried to fix?Mattr567 wrote: ↑Sat Aug 17, 2019 12:42 amThe mainboard will still turn on when it fries, shows mileage, etc. When you press the throttle though the scooter auto shuts off.

When this condition occurs, its basically never the motor ever.

The thick solder is me trying to reinforce everything lol. A bit ugly but 100% functional.
Old one. When they cook there really is no saving them. Just take note of the old mileage and get a new one.
