alternator options for my '07 6.0

[Switchblade2k]

I'm very confident my alternator is dying, batteries are new, aternator is not charging at idle RPMs but will charge above 1500 RPMs...

So the stock alternator is 120amps is I don't have any special electronics but would like a little more power available from the alt...any suggestions?

i've been dying to see how one of these works:
Mean Green High Output Alternator 8478

What about 1 of these ?

I bought a large case 6G alternator (claims to be 200A) from "eagleautoelectric" on Ebay.

Had it for a month or so now, and so far it seems to be performing well.

It is less expensive than buying an OEM Motorcraft... which would be a re-man alternator anyways.

Is it really 200A? Who really knows where that rating comes from... while I do have a clamp-on DC ammeter, I'm not about to torture test it to find out.

I know as soon as I installed it, it was putting out 110A at idle, versus the 80A that my intermittent small case 6G was doing... so that was an improvement.

Sure, there are more expensive alternators available... but it doesn't sound like you need to go down that road.

Price was right for me to give it a try. Fixed the alternator I pulled off, so I have a spare if this one goes sideways.

I got mine from orielly's and it seems to be doing the job. dont remeber what it puts out but I know its more than the old stocker.

Tenney Alternators has a 270 amp alt for $250. if you you remove the overdrive pulley and replace it with it with the stock one you will be able to use the stock belt. the amps will drop down to 240 amps from the 270 amps. they are very popular high output stereo crowd.

After 2 bad remans, I bought a new Bosch 135a alternator from Advance Auto. $200 + tax, less a $50 off $175 purchase coupon I found online. The website claimed 7-10 days shipping time, but it arrived the day after it was ordered.

The Bosch part # is AL7606N
Application was 2006 F550 with dual alternators; this one is the primary alternator in a dual alt system

The alternator case is a little larger than the stocker, but it's a direct bolt-in and the plugs are exactly the same.

Hardest part of the job is getting a ratchet on the belt tensioner, at least it was for me (I'm short).

Glad you got it fixed. In regard to the tensioner, a 1/2 breaker bar with the detent ball ripped-out works pretty slick
