Alternator going out replacement?

So as I thought for a while my alternator been going out Ford said it isn't but I just got new Battery, Massive Wires, MSD Coilpack, and Copper Core Plugs. Dash still dims lights dim cd player dims, only other possiblity is the Alternator right? My friend that help me install my Coilpack< The Star bolt where stripped> Notice m lights dimming and he also said it had to be the alternator. Anyways my question is, is CFM 6G Alternator 130 Amps the only option we have and the best? Also while doing that going to get a Felpro Top Block Gasket kit took the old plugs out and they where honestly dripping in oil....

I have the same issue. Car also tries or does stall every now and then when coming to a stop. Had my alternator tested and it was fine, but the voltage regulator on the alternator was dead. I have since replaced it and the battery, but still having issues. I Think the plug that connects to the voltage regular on the alternator might also be dead. Just something you may want to check before replacing the alternator. Anyway, I just bought a replacement off of eBay from a company called DB Electrical for $93. The alternator is one of the few items on the SVT that is shared with the regular Focus. If you can afford $239 for the CFM 130 amp alternator, I say go for it, I just couldn't afford that much. Anyway, here is a link to the DB Electrical alternators on eBay: http://www.ebay.com/itm/NEW-FORD-FOC...&forceRpt=true

Well I replaced 2 parts store brand alternators in a year. Then maned up and bought a Motorcraft one. All's been well now.
If you do some digging you'll find similar stories from many.

Moral of the story is do it right or do it twice.

you can replace the pigtail harness, clean everything, inspect every wire... but its prob the alt. I was in the same boat about a month ago. go to a parts stor and have them run a test. I got my alt at Oreilys, OEM ford, still runs strong. I dont have sound syst or coilpack or plug wires though.

I got a brand new one from Autozone and I had it for 17 months so far, I installed a voltmeter so I know it works. I learned that reman alts are crap when I owned my last car.

DB Electrical and Autozone (non-reman) specify an alt with a clutch pulley for the SVT even though they didn't have one from the factory. I guess it cant hurt with the higher RPM that the SVT sees. I gave it a try and it's been on the car since.

Here's some high output ones for decent prices.

And they have the $93 standard output standard pulley previously posted on the ebay link.

Hey Sniper Focus, while we're on the subject of alternators, after I installed the DB Electrical alt on the car and started it, I got a pretty loud belt squeal sound for about 30sec. Figured it was just the belt realigning, but every time I start it now when it's cold it squeals for a bit. Just wandering if you had that happen or might know what's causing it. I figured it would have gone away after a few days, but it's been over a month now.
