ive been having to deal with a short somewhere for about a year now. it drains the battery very slowly. ill take my dvom and itll read 12.56 and a day later itll read 12.43. i kind of ignored it for awhile cuz i thought my alternator would charge it enough so it wasnt an issue but i dont drive it everyday anymore. theres been a few times where i had to get a jump from people at work or itll stall out at traffic lights and not have enough juice to start back up again so its getting quite annoying.

ive tried the fuse method where you take out a fuse one at a time and check to see where its shorting and so far ive got every fuse out of the panel and all of the relays and the battery is still being drained. its not the battery cuz when i disconnect the cables the voltage will stay put. the alternator charges the battery at 14v so right now im stumped.

So just to make sure, when you connect/disconnect the positive terminal on your battery, does it spark?

If you have a parasitic draw on the battery, you should see a spark when you are reattaching the positive battery cable. Leave the headlights on, disconnect the battery and then reconnect the battery. That will let you see what you are looking for. Then you can put each fuse in one at a time and then drag the positive connector of the positive terminal of the battery.

If there is any draw, it will spark. Try it with the interior lights on instead of the headlights. The spark will be smaller but definitely still there.

Sorry ar about your trouble! I have a similar problem and have had to resort to using a switch on the positive terminal. It is a real pain in the butt to have to pop the hood every night, but that is the only resolution to the problem that seems to work. As you stated, I am sure that the draw down is very small, butover a few days unused, it leads to a depleated battery. I do notice that the radio clock is always on though. Is that normal??

The radio clock stays on with the ignition off all night? That is not normal.
