Do everything spareparts says saying that here is my opinion.
So you put 5he neg a nd positive on the wrong terminals. If you didn’t try to start it I would try to start it after you put the positive to positive and negative to negative. Maybe you lucked out. As long as you didn’t try to start it. I don’t know if I’m right or wrong but 5hats what I would do. But spareparts is the man. He knows .
