I'm trying to put together a treadmill motor and controller for a lathe build but ran into some issues. Lights flickering, smoke etc..
I had the board wired using a DPDT toggle to reverse the polarity of the DC between the board and the motor. Everything worked great. I tried to put a 3 position, 12 pole rotary switch in to replace the DPDT toggle and as soon as I rolled the pot forward the board made a cracking noise, started smoking and the reset switch on my power bar shut everything down.
I removed the rotary switch, connected the motor directly to the board and turned everything on and again, as soon as I rolled the pot forward it made the cracking noise, started smoking, and the motor went to high speed. I turned everything off and noticed that two resistors on the board (R12?) were fried.
I'm hoping someone can advise as to A) what did I do wrong? and B) is this board done for?
In case it isn't glaringly obvious, I'm new to this so any light you can shed on this would be tremendously helpful.
