I can't understand any of that. The replacement controller was replaced, the controller you wanted to put in is out, and the one you took out is in. Is that it? Not that it matters because you still haven't explained what the problem is. Did something catch fire? Was your motor going too fast? Did the motor run by itself? What inspired you to come to the conclusion that the controller that you may or may not have replaced with one that might or might not be faulty is faulty?
