Parasitic electric drain

So I came home from a 10 day trip and my new battery was dead. I just replaced it because another battery died on me. I thought it was a bad battery, but now I see that I have parasitic drain.

I used a test light to check the system and the test light is on very strong with all items off and doors closed. When I pull fuse #12 the light goes out.

There are no other lights on in the system normally when the doors are closed. What could be in the #12 circuit that is draining?

Also, whenever I hook up the electrical wires to the switch for the engine compartment light it blows the fuse.

Thanks,

Sean

Do not have any electronics, like a digital video camera, near the gas tank while it's open....

Why does Steve keep women's hair accessories around the house?

The fuel filter you're using in the tank boot has about a gazillion times finer filtration than the pickup filter that came with your Spectra pump -- you can throw that pickup filter away.

Why not put an elbow on your pump boot filter and screw the pump into it, eliminating that short piece of hose altogether?

How certain are you that your door lights are going off when you shut the doors? If they aren't going off and are incandescents, that could be your very problem.

I am probably wrong since I don't know what goes to fuse 12 but I just thought I'd mention it. Its just a thought.

Just peek through the crack between the door and its adjacent panels. If the door edge lights are on, you can see them quite clearly.

Of course if the door edge lights are on, the courtesy lights should be on as well, unless a PO has significantly modified the circuit. It's pretty obvious when a door plunger isn't pushed in far enough.

Purple junction is under the console. If you don't mind cutting it apart, it will very easy to isolate which wire has the drain. When I cut apart my Red/Orange junction while repairing damage and rewiring from my burned up headlight switch, I just used a wire nut to put them back together -- hasn't failed me yet.
