If you drew down the battery to 3v, you have another problem vs a little parasitic draw.Used my Fluke to find a parasitic draw on my battery. The battery is new. The engine was slow cranking after only a week of sitting dormant. After two weeks, nothing and the multimeter showed 3V on the battery. Recharged fully and drove it around a bit. One week later, again with the slow cranking and ultimately failed to start. Waited for the whirrz, bells, and whistles to stop after hooking up the multimeter in series to check amperage, the car was pulling 260 to 320 mA with nothing on. Started pulling fuses and the draw dropped to 20 to 80 mA when I pulled fuse 46 (110V AC outlet in the back). Years ago I added a USB and DC power adapter to this circuit and routed under the back seat for the kids to use on trips. Tomorrow I will see if this is shorted out or if something failed on the converter itself.
How long did you wait for the BCM to go to sleep before doing parasitic draw test?
