HAHAHA alternator goes out... again

[TrickStang37]

Ok, this is the third alternator to go out on my cobra. I installed a volt gauge with this newest alt, I figured it was going to die, I just wanted to know when. I knew it was gonna go out, it would charge at ~14.7-14.8v (too high, before that it was doing fine at ~14.2-14.4v) on the freeway these past couple weeks, and would dip into the low 13's with the high speed fan on and into the 12's with all accessories (A/C, lights, interior fans, etc.).

I've learned my lesson, i'm going to buy the cheap sh!t from AutoZone since it atleast has a lifetime warranty.

GOOD IDEA! I have a cheap one from kregan....never had an issue. I've had it for almost a year and a half now...not that it matters. I have a lifetime warranty as well

I love when my alternator gives...gives me a reason to be stuck on the side of the rode.

All three were new Ford alternators?

 

[TrickStang37]

My stock one, one Factory Ford, one rebuilt from a reputable shop, and now Im sure some Kragen/AutoZone alt's will follow too.

Its weird how some go thru lots of alternators and others still have thier stock one with high miles.

you're wrong! as long as you have the correct matching alt pulley it will spin at the same as a stock lower.

to the OP, are you running a lower with the stock alt pulley?

i'm still on my stock alt with no problems.

What matching alt pulley do I need for a 4# lower?

3.2 Is the correct one. What size is your upper?

I run a 3.5 on a 3lb lower and a 2.8 upper. So far so good, one week. I have burnt through 3 alternators in 3 months so the 4th one I put the pulley on. Hopefully it stops the problem.

i'm using the stock lower.

my stock alternator lasted ~45,000 miles. The other two lasted < 10,000 miles each.

But he doesn't have a lower. And as stated, if you match the alternator pulley you should be fine. A ton of people have a larger crank pulley and they're fine. It's the luck of the draw for the most part. JMO.

Wrong i have a lower along with the stock alternator, correct pulley, a tv,75x4 kenwood amp (for highs/mids), a JL 250/1 (for 10w6) and 50,000 miles no problems.
