Hi all,
So I have a strange problem with my controller. Its a scooter in case. I run a EV repair shop and fixed hundreds of bikes and scooter but I haven't had problem like this.
When I turn on scooter motor is hard to turn. Like all 3 phases are shorted. When I measure diode mode turned off all mos are good. When turned on all phases show short to +. When I disconnect hall wire wheel can spin bit all halls are good I tested them with 3 separate devices. They are not shorted to anything.
Than I took controller from another same model pf scooter, Ducati pro 2, placed that controller and the same thing happen.
I tested the motor with completely different controller and motor works absolutely fine.
It's a mistery I can't solve. Only thing I don't have spare is display but could display make such error. Like it's giving signal tu run all phases at once. Never had a case like that.
Anyone had some similar problem?
Thank you all
