My Jaguar is killing batteries.


Asked by biglos253 Sep 27, 2012 at 07:40 PM about the 2002 Jaguar S-TYPE 4.0

Question type: Maintenance & Repair

My Jaguar 2002 S-Type V8, keeps killing batteries.It usually last about 2 weeks before it dies. I've replace the battery 3 times, lucky for me they were under warranty. So now I figured it must the alternator, so I replaced that and my battery died again. Whats going on?

You must have an electrical drain somewhere. An electrical component probably isn't turning off when you turn the car off so it is drawing from the battery and causing it to die. Do you have a multimeter?

You will want one that can handle at least 20 Amps. Don't cheap out or you will just blow the fuse on the Multimeter. Turn the car off, set the multimeter to about 2 volts (2V) and remove one fuse at a time, plug the multimeter fuse adapter (should come with the multimeter) and test each fuse slot at a time. whichever one is showing power when the car off, there's your problem. Make sure your doors are closed because could trigger electrical systems to be turned on like interior lights and clocks.

Do you have sounds installed in your car? If you do check for a wire that's no grounded....before you short out your whole electrical system.....but first do what joef said which is very good advice...LayDee511


No, sound system...all factory.
