lights dimming at high rpm...

[gravey32]

I jus bought a alternator a month ago from advance.. and now its dimmin at high rmps... is this my alternator again?... i heard they get overspun...

 

[gravey32]

Are those ebay alternators any good... or who else is good?

Yes its the alternator again. Very likely.

Let the debate begin for to which one to go with.

I'm running a BRAND NEW 135a off of a Aluminator, direct fit to the 03-04 cobra despite the picture the catalog shows. So far, having great luck with it. Being a all new Ford alt, I totally expect it to last 20-40k miles (stock 110a lasted almost 70k). I have been told that you want to keep the original rotor and windings. I have my orginal alternator that i will hang onto and have a local shop go through it and keep it as a "spare". Something about the way the wires/leads are secured to the rotor, and the "varnish" that you find on most re-mans is crap, note the OEM windings are a yellow VS the re-mans thick, brown coating .... which I guess leads to trouble. As well as cheap re-man rotor leads flying apart (chinsy "soldered" leads that fly loose under RPM). Nothing is as durable as a Ford OEM voltage regulator.

... Just my .02

Have never ever had luck with an auto part store alternator no matter what vehicle needed replacement. OEM at a minimum for my vehicles unless I do an upgraded one.
