Why would the NAV system be using current if the car is off? Anyone have any ideas? BTW, I don't have NAV in my car.

Just a thought. Your alt could have an internal short slowly draing batt. Happened to my mark 7 lincoln years back. Ran fine every day. Charged battery while running. Slowly discharged batt when not running. Whenever it sat more than 3 days wouldnt start. 2 days it was good but turned over just a tad slow,,,Hope this helps.

To add to the above posts concerning installing an ammeter between the + post and the + cable. Then what you need to do is remove and then replace each and every fuse one at a time and look for any noticable current drop on the metter. If the reading changes then that is the source of the current drain. Just be sure that all the doors are closed or tape off the light switches to shut off the interior lights.

well my moms huge conversion van had the sam problem. she went to experts and they could not find the cause of the drain. i finally found the problem being the genious that i am. it turns out the mirror light was staying on because when it shut it was suposed to hit a very small off button that had gunk on it and wouldnt press in

Ok, I hope this helps...I went away for a week a came back to a dead battery in my RX-8 as well. I did the multimeter tests unplugging all of my aftermarket electronics 1 at a time to see if somehow they were drawing electricity. After about 2 and a half hours of testing, I move to the trunk to see if anything in there is on and when I go to open the trunk I notice it is not latched closed but looks like it is closed. VOILA! The voltage draw drops in HALF when I close it fully! No problems since. The switch for the trunk has VERY tight tolerances soo I would check that BEFORE anything else.
Hope this helps

"Even if the instructions that came with the charger do not specify to remove the car's battery cables?"
Yes, you're pushing electrons "the wrong way". This can make things like the alternator's diodes unhappy. Low-current devices like trickle-chargers might be safe, but why take chances? Alternators and ECUs are expensive items, and worth 30 seconds to protect, imo. If it says "charger" I remove the cables.

heheheh Electrons don't flow the wrong way.. heheheh
unless you reverse the earths Magnetic Poles ....
Have you ever head of a Battery charger booster? The 2 units that i have can also start the car.. I.E. jump start the car..
How do you do this with the cables off?? .....
Anyway.. my 8 was killing the battery because of the trunk light switch.....

so far i have just been closing the trunk lid a little harder ..
I discoverd that is was the trunk light when i hooked up my battery to the charger.. Then i let it charge for a few mins with me in the car.. after a few mins i opend the pass thru and sure enough the trunk light was on..
SO now I have to slam the trunk.. so far that has fixed it..

I cannot shut my trunk without a good swift swing, it either latches or it does not ........ is there some in-between state you're experiencing?

Careful, I bite!
Out of curiosity, how are you able to use the standard alarm to lock the car, if the trunk isn't closed?
My after-market alarm has a trunk sensor and won't arm if the trunk isn't latched - did they add that or is it part of the standard alarm?

yes.. the trunk will shut and the alarm will arm.. its just not turniing off the trunk light. it seems to be an issue with the contact switch.
but yes the alarm arms just fine..
Now i am just closeing the trunk a bit harder

had the same problem... now i think the trunk light is happening to me too. i also passed on having the dealer touch it.
there seem to be three states to the trunk lid:
1. open (lights dont flash when alarm arms, looks ajar)
2. partly closed (lights flash but light stays on, looks closed)
3. closed (boom)
