what is the correct amp out put of a stock alternator on a 2000 firebird formula?? i had it tested and its 13.5 volts and 56 amps...i thot it was higher like close to 90....but when i started to drive down the road i looked at the gauge and it is not even on 13 almost 10 or 11(give or take)....also the needle jumps (not alot but it isnt steady) it goes jus below thirteen volts and then will go to 14.......and my check gauges light came on but it went away?? so plz lemme no what you think it could be

yeah i am having a prob with my alt too, they said it had no reading. I heard a lot about keeping it clean as often as possible and the powersteering is usually the culprit. joshiedoom says the job should be easy but i'm still waiting on the damn thing, goddamn ebay

I just had to replace altenator in my van. List was 299. I found 5 or 6 altenator rebuild shops in my area. Cost was around 60-75 to rebuild the one I had. Several years ago I had the last year of the Feiro. I belive is was a 87 or 88. Went to a rebuild shop, they cracked the case and replaced 2 small brushes, that was it. Might be alot more now, but then just 2 brushes. Cost 18. for a "rebuild".

i have the same problem... my power steering was leaking at the input shaft... PS fluid blew all over my alternator and fried it... i'm lucky it didn't start a fire... if you're ordering a new PS rack make sure you get your suspension code off the driver side door sticker...

ya once i get the car lifted and the alternator off ill look at the PS pump and see where it is coming from what kind of alternator do you all recommend??

**Firebirdformula** · 07-14-2009, 12:22 PM

get a stock ac delco one...no need for anything fancy. but you can also get the 150amp ones for the silverado ..and take off the black backing and swap them. however 105amp is fine

My alternator is being replaced now. I was shown the voltmeter demonstration. Unfortunately, I don't own one, or I would have checked it before. The first sign the car gave me was the Check Gauges light, and things went downhill very quickly.

**Firebirdformula** · 07-14-2009, 08:44 PM

how much are the sc delco ones kuz my friend that works at orielys can get me one for 80 bux

**rideon1200** · 07-15-2009, 03:39 AM

Did you really pay someone to replace your altenator? 2 10 MM bolts and 2 wires...... Anyway, if your friend can get it for 80 bucks jump on it.

I just had to replace my wife's alt in her 99 Camaro V6. Seems to be the season for alts dying.

Got a part number for this ?

**shady milkman** · 07-15-2009, 04:09 AM

no i do not..however be warned...our alts are in 135mm casings...the 130+ amp alts are in 145mm+ so fitment will be tougher

3 bolts for the braket... watch out that the alternator doesn't fall on you when you get the last bolt out... hold the bracket and the alternator...
