Question about 2008 Ford Mustang
I would like to know if the test on the alternator could have been done incorrectly?
I suspect either a bad voltage regulator (should show up on the alternator test) or something is draining the battery when off. Draining a battery below 12V can cause un-repairable damage to a battery although if only a few weeks old you might try to recondition it with a reconditioning charger.

180 milli-amps is way to much draw,ford's limit is 50 milli-amps but typically we usually only see around 20-30. Now when you say fuse 2 is that in the under-hood fuse panel or the interior fuse panel? And if this vehicle is a 2007 it may still be under factory warranty which was 36 months or 36000 miles providing that the add on automatic starter is not causing your draw.Which in that case the people who installed it should be responsible for that.

did you change your battery or have a load test performed on it,it could be bad.
Have your mechanic change the wire harness for the alternator at the plug,they can burn out on the inside and look good on the outside,They are black 10 guage with orange stripe,and smaller guage plug wires.This part canbe purchased from the parts store, or dealer.

It could mean the alternator has gone bad already... with the car off, the battery leads should read 11-12V.. with the car on, the battery should read 13-14V.. if it's lower then it's not charging your battery and if it's higher, it's damaging your battery....

Testimonial: "thanks so much for your advice...will have this checked into :)"
Sounds to me that your battery has shorted out and will not take a charge.Disconnect the battery and try to charge it, then check to see if it has taken power with a volt meter. A shorted battery will take all the power from the alternator and run it to ground leaving no power to run the car. Also check the alternator output with a volt meter after you have checked the battery as a shorted battery can burn out the alternator.
