2005 3.0L with bluetooth and nav.

Massive rain flooded the drivers floorboard.
Came here to find out its a common problem with the drain tubes.
And my was kinked.
Pulled the carpet out dried everthing as best as possible. No water present in rear of the vehicle.
Now i have a parasitic battery drain. It lasts about 4 cranks then nothing
the only response from the key is:
Click
Flashing Headlights
3 beeps
the fuel gauge is empty with the light on (fuel is full)
4x4 light on.

The Alternator was replaced 3 months ago and tests fine.
The Battery also passed the long test at oreillys. (5yr old autocraft gold)

Ive tried the amp test which killed two craftsman multimeters 10amp fuse.
Now using a harborfreight 20amp meter.
(Which keeps timing out after 5min)
The Park shift light will go off after 15min.
In x5 sleep/wake mode
Reading 1.77A for the first min then 0.39A until the meter kicks off.
Awake mode= 2.7A with glove box light (.3A difference off/on)
Sleep mode = .11A
sleep mode +15min = 0.0A~ .01A
Sleep mode +20min = 0.5A
Sleep mode +22min= 0.01A

Fully charged, X5 is stationary, 5 hours later only 10.5v

Pulled fuse 74/75 to see what happens. The battery charger sounded like it got a boost when I did that. (Awake mode)
What now?
