Alternator OEM FORD or Duralast

I just purchased a 180amp Duralast New for my X about 2 months ago. The Duralast has done me well so far.

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.

Autozone one here. 3 years deep going strong

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.

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

I have a 2007 Chevy suburban and the altenator died so went to Autozone and purchased a new duralast 220.00. This worked for a few days and the battery died again. Checked voltage and only had 9 volts coming from altenator. Took back the altenator for them to bench test and they did not have the proper connections. Gave me another altenator installed worked great for 2 days. This new altenator was also not working and was given a third altenator.

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.

I have a shitty looking Ford Focus that I maintain myself...The alternator failed and I couldn't be bothered doing the work myself so I took it to the local dealer.

I haven't had this problem with my RX8, but I had a similar problem with my Ford. Alternator was putting out 14.4V, but I still had a light. Took it to the parts store and they hooked it up to their tester. It said the Alternator was no good.

Duralast 11120 (if that's what is on the invoice) doesn't have a lot of great reviews...
