I have a 2003 Ford Taurus, and noticed the battery draining at progressively-shorter intervals. It now drains to where it won’t start, within just a couple hours if the car is sitting with the battery connected. I attached a multimeter between the negative battery cable & post, and looks like there is a 1.1 amp draw. I started pulling fuses one-by-one, and found the following fuses where the results changed:
Below, I’ll list what the draw dropped to on the multimeter after removing the fuse, (the fuse #), and what the fuse chart said it covered. All 3 fuses were under the dash:
-
0.06-0.46 (F2.16)- Generic Electronic Module (GEM), Remote Climate Control (RCC) Module, Instrument cluster, Multifunction switch, Integrated control panel. This showed a 0.06 the first run-through on testing, and I checked it multiple times. After going through all the remaining fuses, I came back to this one, and removing it only lowered the draw to 0.46. (Sub-question - why would this change so much, when all the other fuses had repeatable results?)
-
0.66 (F2.26) - Interior lamps relay, Battery saver relay, Luggage compartment lamp, Extterior rear view mirror switch, Pulse stretcher module, Power antenna module
-
0.82 (F2.10) - Accessory relay, Adjustable pedal switch, Seat adjust switch
where do I go from here?
-
It looks like F2.16 would be the place for me to start. Is that a correct assumption, or does it look like there are multiple issues at hand?
-
It looks like there could be any number of components attached to that fuse. Is there a resource which shows me everything on that fuse beyond the generic list I found?
-
Is there a way to somewhat-easily disable certain items that I’ve had trouble with in the past? Example could include my radio, which eats CDs, or the glove compartment which I thought had a light, but can’t locate it since the glove compartment fell apart.
-
What in general is the methodology for testing beyond here? I found a video on Youtube, where the guy started poking around with an alligator clip/wire combo and ended up snipping wires on a hunch, but I could see that going badly quickly.
