Start by removing the negative battery cable and installing a 12 volt test light between the negative post on the battery and the cable end. With everything off, and the doors closed, If the test light lights up, you have a draw in the battery. Next remove (1) fuse at a time until the light goes out to see which circuit the draw is in. If you pull all the fuses and the test light is still lit, disconnect the positive wire to the alternator. If the test light is still lit, disconnect the positive cable to the starter. If the light is still lit, you have something positive shorting to ground. Bill
