2.54 amp draw on battery

Hello all, my battery has a constant 2.54 amp draw in my 2009 MDX / Battery dies in 24 hours
If I remove #4 - 40 amp fuse located next to the battery under hood the draw goes down to .03-4 amps (normal)
#4-40 amp fuse protects Audio, door locks and interior lights
Door locks and interior lights all work / Audio radio also works which is fuse #5 located inside vehicle
or if I remove fuse #5 for the radio, located inside vehicle amp drops to .54 amps


Any help would greatly be appreciated

If your radio fuse cancels the draw, most likely your radio is the culprit - remove all of the discs from it and see if it changes anything. It helped me. Try it out.

Also try another 40 amp fuse in #4 location pull similar 40 amp from other slot and out in #4 position see if draw remains the same?

radio fuse removal and replace worked for me; it stopped the 550mA phantom draw and the GPS unit spend 10 minutes re-aquiring signal and after that everything seems to be working normal again.
