So I took a very systematic approach this morning. I had my wife take pictures as well (I had a feeling some of the numbers she was writing down were not totally right
1) Idle State, with all fuses/connectors in place: Initial current draw of ~0.45A, drops to steady-state ~0.23A
-I would consider my parasitic load draw to be 0.23A, which still seems higher than normal, and likely what is causing the battery drain
2)Removing the B+3 fuse: Steady-state current draw of ~0.08A
-Is 80mA normal for the Elantra GT?
3)Re-installing the B+3 Fuse: Steady-state current draw of ~0.23A
4)Removing the I/P-D connector as suggested by @AUTOSPARK
, current draw goes down to 0.002A
-pretty much no current draw at all
5)Re-installing the I/P-D connector, current draw goes to ~0.23A
6)Removing the fuses installed in the subject B+3 circuit, the 10A Memory2 fuse results in a noticeable difference. Current draw drops to ~0.16A
-Reduction of approximately 70mA from Memory2
7)Reinstall Memory2 fuse, current draw goes to ~0.23A
Does anyone have an idea of what the normal idle current draw should be for a 2013 Elantra GT? There are few clues in the above as to what the culprit exactly may be, but knowing normal values would help.
Thanks again everyone!
