Maybe you were smart and maybe you weren’t smart. You should have come back to me before you did anything like that. The polarity on the factory power supply is specific. I’ve forgotten what happens if you use the wrong one, but I don’t think it’s good. I’m attaching a picture. The key is the little diagram at the bottom that shows a plus sign, a minus sign, a line and a C. If yours doesn’t look exactly like it does in the picture, you got the wrong power supply.
