Voltage is at zero when jeep is running
On my 2001 cherokee, the voltage reads all the way down on the dash when shes running. Eventually the jeep runs out of battery and can't start. When I charge the battery and put it back in, the RPM jumps up to 1500 (Im assuming its so the alternator will kick on), and when I take a reading on the battery with the voltmeter, the voltage drops like .5 volts every 30 seconds, continuously. Upon shutting the jeep off, the battery has been drained and the jeep wont start.
Is this just case of a bad battery or alternator? I checked all the grounds and they seemed fine.

check the charging fuse or fuses, and most autoparts store you don't need to remove the alternator for them to test it for free, but sounds like not charging, when the engine running most of the electrical load come from alternator + charging the battery, with it not charging the battery has to take the electrical load and goes dead quickly running all electrical parts of the jeep

If it's charging you should read higher than with the jeep off. Take it to Advance, they can test it in the vehicle quite well with the little microprocessor based tester they have there, free and only a couple minutes, with a LED screen and printout of the diodes and voltages under load.
