2002 Mustang GT, 49,000miles. The battery keeps going dead after about 5-6 days without driving. I can jump start it and drive for an hour and it will start fine as long as I drive it every few days. The battery is brand new (2nd one) and I have had the system checked out (Auto Zone) as far as the charging system. I have made sure everything is off, interior lights are not on, the shifter is in neutral, looked for a short but can't find a thing. I have to believe something is energized/shorted and draining the battery. How do I troubleshoot this anomaly and where do I start??? Thanks.

Try pulling fuses one at a time untill you find the one that solves the problem. Now you at least know the circuit involved.

Good hunting. Let us know. :)

I had a van that was doing that one time, I checked everything and was about to give up. On mine the ac clutch was staying kicked in for some reason and draining the battery.

Suggested Repair

Pull fuses one at a time until the battery drain stops, then inspect the circuit on the fuse that solves it.

Conversation Summary

A 2002 Ford Mustang GT owner reports the battery goes dead after about 5-6 days of sitting, even with a new battery and a charging-system check. Lights and other obvious loads were confirmed off, and no short was found. An expert advised pulling fuses one at a time to identify the circuit causing the drain. Another member mentioned an AC clutch that stayed engaged on a different vehicle.
