Tldr: shorted display power circuit, can i fix it (45a hallomotor controller)
Lesson learned, dont assume you know how to wire a controller
So i just recieved a hallomotor 45a controller (says risun on the label). I was super excited to connect it to the motor and might have done something stupid in my haste
I tested it upon reciept by connecting my 52v battery (stupid, shoulda used a multimeter. The controller would make a high pitched whine. I figured it was normal and would maybe go away if i plugged everthing in.
The next day i attempted to use the USB connector to program the motor on my pc.
I had the controller plugged into the battery and motor (only the 3 phase wires tho) but nothing was happening then i realize the circuit supplying power to the display out has no continuity becase i started to make the harness for the display with the unwired plug proved for the display. To fix this i reconnected pin 1 to 3 (red to black or current in to current out) as it came from the seller.
Still nothing
Then i relaized i unplugged the two wires going to the power switch. When i connected the circuit there was a big pop.
I then put everthing back as it came. But when i powered on the battery there was no whine. Im pretty sure i damaged circuitry going to the display.
I opened the controller up and saw what looked like 2 melted pins on a serial connector that was between the main pcb and a smaller pcb with appears to be related to the display. Unfortunately my mutimeter isnt working, so i cant test. Also im out of town now and am unable to provide photos.
If im right should i expect further damage and is it fixable?
Or do u think the seller would accept it if I say it never worked? I regret not buying a bigger controller and not purchasing it with a display so it was thinking about returning it anyways.
