I have a 1990 5.0 LX automatic...It has been eating up alternators like candy [:@] It has been through at least 6-8 alternators in the past year alone....And about 3 batteries due to the this problem
Can anyone who has a similar stang give me some advice??? Or maybe a link as to where to buy a quality alternator that will laaaassst??????????

Damn something is wrong, you have a huge stereo? Whats going in the Altenator the brushes or the bearings? Sound more like a wiring problem to me unless its the bearings going!

deffinitly sounds like a wiring issue i dont see bearings failing in 6-8 alternators... what kind of stereo equip you got ... sounds like theres something putting a huge draw on the alternator overloading and cooking them..

I could see the bearings going out *IF* he/she had some goofy pulley alignment or something.......

Don't ask me how I know

Are you buying new ones, junk yard, rebuilt ????

I don't know if it is wiring problems? I have had them put in by a mechanic that has been working on it for a long while now and knows the car pretty well...But yes, they are rebuilt/remanufactured, I have been told that is the reason why they are not lasting because the rebuilt alternator just doesn't last in that year mustangs or camaros. That the same alternator can be put into a honda or toyota and last for years and years [sm=rolleyes.gif]
As far as I know everything is hooked up where it should be, I have a vacuum hose that needs replacing that I have to order from Ford. It runs really well other than the alternator problem, when I come to a stop, my battery meter goes almost all the way down and if my headlights are on they get really dim, then when I move battery meter goes back up and headlights brighten a little...
I don't have a huge stereo system in it, just a cd player and the regular speakers, no amp or anything fancy, but I got the car from my ex and he had all that stereo stuff in there, which he took out before I got it. I just had it in at the Ford dealer and had over 500 worth of electrical work done on it and the rep there said the alternator I had in there was a piece of crap pretty much and recommends Ford's rebuilt alternator at about 400 buckaroos, which I dun have that much right now to spend [:@]
I have found a guy on ebay who custom builds reman alternators with 6 70 amp diodes and puts out 140 amps for the yr stang I have, and is selling for about 130 bucks.
Everyone that i have talked to has said anything between 75-125 amps would be ok to use, so I dunno lol
Does anyone have an alternator in their stang that puts out that many amps?
I have been told I can't buy a new alternator for 90 stang, lol if anyone knows where to get one new lemme know

hey hon, it sounds like they are running you around. one that mechanic is out there to make money. Fawk him and tell ford to kiss your ****. no alt is 400 bucks. if you continue to have issues i would just use a 1 wire alt. this way you cant have issues. its simple cause you run the alt directly to the battery. its more effiencent.

now if a ground is bad it wont charge correctly and will shorten an alts life

That alternator better be plated in 24k gold for $400... and it better talk to you too Like Quik said, go buy a Powermaster 1 wire hookup for $130 dollars. BRAND NEW! And PowerMaster VERY VERY reputable!

has the Voltage regulator been replaced with the alt every time? I forget what year they actually started including the VR in the alt.
