Hello Scotty. I have a 1996 Mercury Sable. I went to put a battery in it and after I hooked it up, the radio, hvac and speedo didn't work. I found the 5A radio fuse under the dash and it was blown. I went to put a new 5A fuse in it and it sparked and blew immediately and left a burning smell in the interior. What could've happened? Everything worked fine before I installed the battery. Thank you in advance.
