Good Morning,
If I am in the wrong forum, please feel free to delete.
I have an issue with my 09 Hyundai Elantra., I bought a brand new battery, didnt drive the car for 3 days and when I tried to crank it on the 3rd day it did not satrt. So I assumed that I have a Parasitic draw; I tested it by removing the negative battery cable, connected my multi-meter to the respective ends, and I got a reading somewhere around 0.590 AMPS, with all accessories off and the door closed.
I managed to trace the fuse that controls the "thing" that's causing the draw, and it was a 15AMP room lp fuse, located under the drive side fuse box. I did some research and found out that this particular fuse controls a bunch of stuff.
I then went on and started disconnecting the doors harness, to see if the draw would go away but that did not help. long story shortish. I unplugged the harness below from the driver side fuse box and the draw went away. Can anyone give me any info one this harness and what it controls? or any better way to go about this?
Thanks in advance. Hyundai Elantra Parasitic Draw - Last Post -- posted image.

When you first take your reading it'll be high. As you alluded to by the fuse description, it's probably interior lamps. If there are computer modules fed by that same circuit, you may need to wait 30 minutes to an hour before you get an accurate reading.
My ex once told me I have a perfect face for radio.
