I went through 3, iirc on my 2006 mustang. Wound up with a used motorcraft (OEM) that I bought off eBay.
I had a similar problem with my 08 mustang GT. The alternator burnt through the cord going from it to the battery. Bought a remanufactured alternator and replaced it. Still didn't work. Traded it in for another remanufactured. Still didn't work. Finally returned that one and bought a brand new one. Works fine 6 years later and no problems.
I started having problems like my alternator was going bad again so I replaced it with a duralast alternator part number DL2618-6-11 because I had a lifetime warranty on it and it still didn't fix it so I was thinking it may be a wire shorting out was playing around with the wires that go to the alternator and the plug on the back that goes from the alternator to the PCM and it's started charging again ( I guess it finally connected the electricity) so I replaced the plug on the back of the alternator. It fixed it work for about a month then it happen again check charging system battery light on and battery going dead so I was done. I took it to the Ford place they wanted to replace the other side of the PCM to alternator connector which they did and the alternator so I got another AutoZone lifetime warranty alternator and when they did that they said everything is charging and running like it is supposed to be but your PCM is still throwing the battery light and check charging system because your alternator is charging at 14v and for the PCM to cut the light off it needs to be at 14.6 v. So they wanted to put another alternator on it because they said the alternator from autozone the voltage regulator wouldn't let it go to 14.6 volts. The car runs and drives and doesn't have any problems I just hate the light being on to be honest I have spent hours on the Internet trying to see if it's just these AutoZone alternators that aren't letting it get to the volts the PCM wants or not haven't found anything.
My neighbor had a Ford mustang and he had to jump start it about once a week. I checked the alternator and it had power when the car was off. Bad diode.
