Alternator OEM FORD or Mitsuboshi

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 tossed in a Mitsubishi 200 amp P71 alternator into an '06 Town Car after the original 6G on it failed. Very good output even at low RPM

I have experienced my share of faulty Ford alternators from the chain stores. I now get OEM from Ford. Yes, they are expensive but I have better things to do than replace month old alternators constantly.

Did they put in an OEM ford alternator? Fords switched to their “smart charging” system and its a little more complicated than your average alternator diagnosis.

The Taurus alternator and 2 speed e-fan come to mind as the two most common parts that people pickup from junkyards and slap them on to their cars.

Newer ford alternators essentially “talk” to the pcm. Cheap aftermarket alternators do not do well on these cars. Replace the alternator with a better quality alternator

Had issues with every single Ford alt I replaced (from autozone, Napa, Oriellys) didn’t matter. Only had luck with either dealer parts or from a local rebuilder.

I once went through 3 alternators in 2 days from the Ford dealer on one job.

Go with a new OEM. I had a Ford E250 I put a remanufactured one in and it lasted like 2000 miles and gave out.

I had one during college... For a V6 it wasn't particularly quick and handled a lot bigger than it was. In three years it ate five alternators and the intake runner control box was notorious for failing (killing what little power it had).
