Hello,
I have a Golden Motor BAC-281 motor controller, and the motor stopped working properly and stuttered. I took the board out of the controller and noticed that the top of the board is burned. What would cause this to burn in this location? I am supplying the controller and wheel 24v

Any help or input what caused this would be helpful so I do not burn out another controller
 
What happened just before the failure?

Was that any different in any way from the way it was used before that?

What is the system that the motor and controller are used on, and how is the system used?
 
Test email or link this thread to the Goldenmotor company.
(they had a live-chat function on their website, last time I visited)

I guess the big blue resistor, is a shunt, often used as a fuse. Is that 5.1ohm?
