Thumbs down Something is killing my battery

i've been fighting this battle for a while, at first i just replaced the battery, but the next day it was dead again. I checked fuses, and noticed that a fuse was blown, it was the "engine comp l.p." fuse. hoping that just replacing the fuse would do it, i went out and bought some fuses, put a new one in, and jumped it. i let it run for about 20 minutes, turned it off and hoped that it would start today. i just went outside and when i opened the door, no lights came on, and nothing when i turned the key. Im open to all suggestions on what this could be, thanks guys.

got a voltmeter or a test light?
You'll have to probe each circuit and find which one is using juice when its supposed to be off. Thank goodness the first part of this elimination can be done at the fuse box.

No. Your looking for a sneaky amount of current. Your sniffer won't bust that out.

what was the last electrical thing you put on or did before it started draining? almost always is the last thing you did.

Last thing I did was reassemble the wiper motor, but it worked for a few weeks after that fine.

What u need is a test light with a circuit tester , basically its just a test light with an extra power clip that feeds onto a micro board inside the test light , green good red bad . I do heavy collision repair . I cant waste time looking for small breaks on a big job. I have to narrow down quickly whether its a wire or relay or fuse . I find its great for ABS systems for a quick check instead of using the multimeter to check the ohms .

Another way of checking (which people are getting at here) is to take the negative terminal off the battery, connect the testlight clip to the terminal then probe the negative post of the battery. Light on = bad, means current is flowing.
Leaving it connected make your way to the fuse panel and start pulling fuses. Once you pull the fuse that turns the light off you know where your short is. Look at the fuse # and see what it controls.

Scoty Kilmer shows this procedure in his video here

This works on older vehicles.

Give it a shot and see what happens.

I have a similar problem. It is intermittent.
Works great sometimes and then other times will kill the battery over night. I can pull the battery terminal and measure 0.3 amps pulling with the key off.

I pulled fuses and none stops the current flow. I pulled the alternator connector and current still flows. That eliminates voltage regulator right?

What circuits DON'T run through the fuse block?

I know this is different but it may be of some help.

I had an issue very similar to this but also my truck would die while driving. I had replaced the battery, the hot battery cable, and fuses repeatedly. Found out later that the alternator wire by the fuse box had worn off the shielding and had been grounding out on the body.

Something to look into, do you have any direct shorts because they will cause the issue.

Outcast,
What alternator wire is near the fuse box?

sounds silly, but a friend of mine had a similar problem. turns out, the glove compartment light switch broke off. so when the glove compartment was closed, the light did not turn off, draining his battery.
