Customer Question

I have an 08 Jeep Grand Cherokee 5.7 Ltd . The battery goes dead in 2 seconds or less, when I leave the key in it after I turn it off the battery tests good with a load tester. The charging system is good also the starter is good. If I hesitate in pulling the key out, then try to restart it, the battery will be dead. The battery will indicate 4 to 6 volts. A load tester will verify this. A code reader shows no discrepancies. ???
