    Try a new alternator. Some have reported getting bad replacements.

  • beware the batter is all time due of mustang ford mustang 2005 alternator will make batter die all about the amp`s coming out of the alternator what i trying say replace the alternator or rebbuit .
    then charge the batter slow charge setting . do a complettle charge .. i`m still leaning about my mustang ..

    ps. do not wait to long to replace your alternator it kill your batter and cost more money in the [non-permissible content removed] ..
