i recently attempted to replace my own car battery when i took it to the shop they indicated the battery was dead. However the battery sold to me had the pos & neg connections in the wrong locations and i connected the battery incorrectly. When i figured out my error i returned the battery and attempted to install it. Now i have now power. I've checked all my connections and still nothing.. Is it possible that i blew out something by putting in the 1st battey with the incorrect connections?
