The battery drains at the same rate with the key off as when its running. All the fuses pull current when the key is off. The battery dies in about 12 hours completely.
are the lights, clock, and radio on and functioning when they are pulling the current you are measuring?The fuses all have the same current with the car running when the car is off and the key is out and its as if the car thinks the key is still in the running position. Each fuse but the lights, clock and radio pull current.
also, if you unbolt your starter cable and check it it is probably really corroded. if you have green dust flaking off it is corroded. you may want to replace that cable as well. your battery terminals may also show signs of this as well. power is funny like that. it looks for the easiest place to escape.what you need to do is an amp draw test. take a volt ohm meter and disconnect your positive or negative terminal. place one lead to the battery and the other to the terminal that is not hooked up. set your meter to amps and start pulling fuses until the meter stops changing. which ever fuse you pulled that made it stop is the line with the problem. if this is a new problem for you, before you try this you may want to check and replace faulty ground straps and cables. if you have weak/bad grounds your charging system will not hold a charge or take a complete charge simulating dead battery in short time frame.
its not pulling 12 volts. it is showing available voltage. it only pulls if it is on. do amp test. there are many items in the car that have 12 volts all the time.its done this to three different battery's and i put the negative to the negative post on the battery and the positive on the exposed part on the fuse and it pulls 12V i think with the key out it doesn't have a stereo and i didn't say that because that shouldn't make a difference. With the lights off it has no voltage. The clock doesn't work any way so it shouldn't matter. Also i just noticed that it keeps blowing the light bulbs. I use the H4 conversion lights so its not the huge one piece lights.
Is your power antenna broke? If so it will cycle key on or off Drove me nuts for a day until I had my head in trunk and heard it.i got this same problem but i can go for a day and a half before mine completely dies...i did a voltage check and not a current(amp) check also.
If you do this test, make sure that you have both doors closed or you might be messing with mutiple problems that you don't need to be.wtf seatbelt retractors? what version do you have?,
all you have to do is get an ammeter disconnect the negative cable and connect the ammeter inbetween the two, if youre getting more than like .2 amps then you have parasitic draw. next you have someone look at the ammeter as you start pulling fuses in order ( start with the ones under the dash first) and once you pull the one that drops the excessive amps you locate what that fuse went to and repair the problem, most likey a trunk switch or something that switches on a light that you dont notice.
