I have a 91 PA. The battery always seems drained. If I jump it and use the car everyday it runs ok. Initially I have to drive the car for several miles after a jump to maintain a charge to start it. If I leave the car parked for a couple of days the battery is dead again. It only shows 8 volts on the gage. What is draining my battery? I already disconnected the auto leveler so that is not it.

To track down a battery drain problem, you first need to see the drain. Your tool could be either an anmeter or alternately you can construct a light bulb with two leads so that it will glow when there's electricity flowing.

Procedure:
1. Disconnect the negative battery cable from the battery.
2. Wire the two leads of either the anmeter or light bulb tool between the disconnected battery cable and the negative battery post. You should see the battery drain at this time on the anmeter (or see the light tool lit).
3. Pull the fuses in the car one at a time, and observe if the battery drain stops. When the drain stops, you've found the problem circuit and need to investigate why.
4. If you've pulled all the fuses and saw no change, the problem circuit may be one with no fuse in it like the alternator or starter circuit. You would need to disconnect them manually to test.

yogi123rd pretty well covered the slueth work of finding a parasitic draw.

Another possiblity although rare is a shorted diode in the alternater.

My Twilight sentinel drained the battery two times. Problem enden since i pulled it off.
