XC60 2013 B6324S4 I have a parasitic drain of 3.94 amp. ALL FUSES and relays, including the fuses under the engine fuse box (C: very hard to get out), 2 fuse boxes under dash and 1 in the cargo area have been pulled, with no change in meter reading, Alternator was changed out due to suspected diode leakage and this is the 3rd new battery in less than 1 month. Even ALL the relays in the engine bay have been pulled...NOTHING. When putting a DMM in line with the battery, besides seeing a spark at the DMM probe I will sometimes hear what sounds like, something energizing within the intake manifold. I have removed the 2 upper electrical connections on the intake manifold and still hear this energizing noise. If I put the DMM (amperage check) on the battery and I open the driver door I also will hear this manifold energizing something. I also did a voltage check on EVERY fuse, to see if that would show something.......nothing. I took off the door electrical connections which was pretty tough.....nothing. I go out to the car at night with the battery connected and I see nothing lit up. I looked and I do not have heated seats as I assume a 4 amp battery parasitic draw should be something to draw that much amperage. NOTHING aftermarket has been added. I have wiggled wiring harnesses in hopes to see something......nothing. Does ANYBODY have any ideas? What have I missed?
