Posted via FF Mobile Don`t like the disconnect battery test, that trick can kill an alternator that was previously perfectly OK.A good alt can charge a dead battery, it just takes a bit of time - not fully charged in an instant. It can`t charge a bad batt. however, and trying to does put an undue load on the alt., potentially hurting it....
