Changed alternator and now electrical is messed up, need help
My son has a 2012 Cherokee 3.6 automatic. The alternator was whining and the battery loosing charge so he changed id out yesterday. Now the wipers won't go off a it's rought going into gear especially reverse. Checked fuses all fine and don't know what to do now. He checked connections and all look good. No problems with electrical until alternator was changed.
