I mean your not reversing then. I seen cables burn from bad grounds as well..so check your grounds. When you replaced alternator, you did make sure to put washers back exact way right? sometimes their insulators. and improper install will cause that...So some stuff to check. now go ....go check...lol
Well maybe ill just go back to walmart where i got batt from and tell them to check it for me ,and yea i think i did everything right bro i change the serpintine belt and alternator put everything back the way it was man im confused
