Best replacement alternator?

[emperorjordan]

Well, tonight my truck's battery light started flickering and my voltage started fluctuating like crazy on the gauge, accessories started cutting out, etc. I pulled over right away, checked everything and I am pretty sure its the alternator. I just pulled it off, the batteries are pretty new I am hoping it didnt take them out with it.

I am going to go first thing and get the alternator tested, but it is currently a reman chinese piece of **** that was on the truck when I got it. Assuming it is the alternator, what are your suggestions for alternator?

Parts store chinese 110 amp stock replacement? parts store 120amp upgrade replacement? Should I see if the dealer has a better made option?

What about the USA made MEAN GREEN alternators found online? Any good/bad things on those? They are almost twice as expensive but they are 200 amp and made in the USA.

I searched around a bit, but found no good answers on which alt to buy just lots of threads on how to take then alternator off, which was pleasantly easy.

X2 on the DC Power alternator I bought the 250a but they sent me the 270a I have not had a problem since. Do your research before you buy, the 12 larger diodes and heavier windings verses 6 standard diodes and wiring was my selling point. Dissipating heat is the key to longevity with a good alternator. If you go bigger you have to address the extra output and upgrade your cables accordingly in the end the investment is well worth it if you plan on keeping your truck for several years. I have mine built the way I want it and do not plan on trading it for several more years.

I just installed the powerbastards.com 220a alternator. (High Output Alternators and Accessories | PowerBastards.com)

Great prices, good warranty, completely new alternator was used to build the alternator. Mike is a great person to deal with, sent me the wrong pulley called him up and he expressed shipped a new one to me, got here in 2 days.

I also upgraded ALL my battery cables and alternator cables at the same time. Just piggyback the alt cable with my 1/0 gauge wire.

Got my alternator tested at AutoZone and it tested fine.... wtf I am lost now. Not sure what to try next.

I had an alternator once on another vehicle that was cutting out. It was brand new and when I brought it in to be tested it tested fine. Ended up in a big disagreement with carquest so i finally returned it and bought one somewhere else. no more problem.

My point is, i think having it tested is fine, but conditions are different when you're out driving vs when it's on their stationary testing set-up. It's probably a sign that it's at least on it's way out. Might as well replace/upgrade it before it takes the batteries with it. Just my opinion

I am going to buy a cheapie reman and put it on and if that fixes the prob, I am going to try to return it and then get a DC power alternator.
