alternator troubles
I am on my third alternator in three months.
Is there some possible reason the new one keeps failing? Could the old batteries cause the alternator to over work itself?
'04 6.0 CC Auto 4x4 with 81,000 miles...completely stock, original batteries....bought truck 10/03.

back a few years ago, i had to put the third alternator on a vehicle, with 12,000 miles of the first one and all of those were motorcraft alternators. sometimes it just happens. you can get the batteries load tested but i dont feel like this is the case.

I have heard of people putting 2-3 alternators on before finding a good one.
[rant] That seems almost rediculous but I know it has happened. I mean, what if NASA had to go through 2-3 alternators to get a good one? OK not a valid comparison but in 2006 you would think that FoMoCo would have there suppliers in line by now. [end of rant]
I just put one on at 95,000 miles. It was a Motorcraft unit. I now have 5000 miles since then and no problems - yet.

yes but in all reality is is us the consumers fault. we want cheaper, cheaper cheaper. so we get cheaper, not better. have you ever bought a alternater for a nissan or a honda? atleast 600 bucks for beginners. but how often do you have issues? that is why american market autos are struggling to compete with over seas.
and nobody cut me i know i am hijackin!!

Just as a suggestion, make sure you check the no-brainer stuff ( engine ground, low front pass side on the engine--ground strap on the pass side rear of the motor--of course, batt terminals)

Why would a bad ground strap or corroded terminals kill the alternator?
What other problems would arise with these issues?

I looked for the RF ground for the engine and didn't see them. I was looking for a flat braid ground strap. What are they close too so I can get a better idea of exactly where they are? I want to clean them and see if it helps my RFI problem.
Thanks
