Noob here. I'm trying to connect a used wheelchair motor to a power supply but I keep burning the speed controller (3 so far). I connected the motor this way and it will run for a few seconds to a few minutes. When I dial the speed down and try to dial it up again it will cease to run. The speed controller gets hot and a chemical smell emanates. The last controller would only start running again if I checked the voltage in CONNECTION B.
Can one of you experts take a look at my diagram and specs and give me some guidance? Is there a chance that the problem lies with the used motor? Thank you.
