Sure the meter is hooked up right? I have never seen a draw less than about 20 to 50 mA on a modern car after all the modules have gone to sleep.
This question, along with your unusually low posted parasitic drain current readings has also caused me to wonder if your meter settings, or lead connections to measure current are in question.
Don't know what brand multimeter your using, but most multimeters have test lead plug-in jacks to enable the meter to measure large currents, on the level of about 10 AMPS.
So if your test leads were thus connected, your readings might really be .15 amps, or 150 ma & that would be more in line with whats expected.
Now if that level of parasitic drain continued, it could draw a battery down.
Yet more thoughts for pondering.
After work I will recheck. Something I just remembered that may have something to do with my problem. A couple of months ago the day time running lights quit working right, they were real dim and the bright light light on the dash stayed on all the time even when the car was off, it went out only when you turned on the lights. After asking around I was told to just pull the fuse, so I did and the light went out on the dash and the DRL
do not work at all.(Which is fine with me). Again I do thank all of you who are trying to help me. Glad I found this site.
