I have been fighting a battery drain issue for some time now. I built a stand alone fuse panel for any aftermarket items (line lock, gauges, n2o, bottle warmer, and gauge lights) to isolate those. I went and tested with a meter and after pulling every fuse under the dash moved to the under hood fuses with no drop anywhere. I then started pulling main power lines. I pulled the stereo main power (aftermarket system) no drop, I pulled the stand alone fuse panel main power and nothing, and I also pulled the alt power source with no change I also pulled the other 2 alt wires just to make sure.
The only thing I can think of is maybe I am setting up my meter incorrectly? The reason I think this is the only way I can get a reading with the (-) neg terminal undone it is (- 5.87) and that does not seem correct.
I have the black lead on the COM slot and the red lead plugged into the Ohm slot. The dial is on the black 20M on the Ohm side (3rd click/spot clockwise from off)
