Any thoughts on this approach?
I hope that's a good approach since it's the one I just took. My alternator is taking a dump, it would seem. It will occasionally hit 13.0 or so on my SGII, when 13.8-14.0 used to be the norm. I ordered the Bosch last night and will stash the old one away in the trailer just in case since it should still be good enough to finish the journey. Wish me luck...
ME2- Good luck and please report back your results with the Bosch alternator.

I was just looking at regulators for the 6G
and found that you can get them anywhere from 14.0 to 14.8
for the set point. Have a look.
The reason I got to looking was I took the 110 AMP one apart
just to see what was going on inside. I could hear a scraping.
Turns out the slip ring was going bad and very uneven brush ware.
I'll post some photos later. I found the slip ring kit on this page also.

I didn't have any paper work at AZ. They just ran my phone # in their computer and said I was good to go. Your O'Reillys doesn't sound like to good of a store to deal with.

I also had the batterys pulled out the truck when I went in there
They did fail hydro test so and that's all I had to tell them At no time did they check
Plus I went into store about 5 minutes before closing I think they would have just about gave me anything LOL they wanted to go home
My free replacement was just about out so if they didn't want to make it right I was going to Nuetralize a cell or 2 with baking soda and kill the battery and take it back
I thought if they want to give me a Hassel bring it on

Sean,
I had the same issues with Oriellys. what I did was drive to the parking lot. turn off the truck, sit for 5 min turn the key on run the glow plugs and take the surface charge off the batteries. then go in and have them come out to test. then both batteries were at their "real" level. they then honored the warranty.

mounted very far away from ANYTHING.
it's not mounted directly to the engine, but it's all of a half inch
away from it, it seems like. ed the ficm wizard says however,
that he's had very few ficm's fail on E series, compared to F
series... his remark was iirc "just a handful of E's have failed".
his speculation was that the isolation from vibration helped a lot.

in my experience, NOTHING in a E-350 diesel compartment is
mounted very far away from ANYTHING.

Vibration too no doubt about that.
But that was in response to someone be opposed to outside air and rain possibly effecting the FICM... When international on their own trucks mount them outside totally exposed to the elements.

6G Series High Output Alternator with Extra Heavy Duty Components
Also has anyone done this mod from the FICM repair page?
13. Upgrade your alternator wiring. Run a wire, preferably with an inline fuse in it, from the stud on the back of the alternator directly to the passenger side battery. Augment this with a wire from one of the alternator mounting bolts to the vehicle frame. Doing so will allow the alternator to begin charging the batteries immediately upon vehicle startup rather than having to wait for the glow plugs to turn off before charging is allowed as with the stock set up.
With an OEM alternator (though see #14 below), use not less than 4 gauge wire. With something bigger, go bigger. Many use 1/0 wiring (about the size of your thumb) for this task.

I replaced the alt and both batteries a year ago. Alt is a rebuilt Bosch unit from Napa that is showing 13.4-13.8 and occasionally up to 14 on SGII. I'd like it to be better than that so I want to do the 6g upgrade. BTW first alternator I got from Napa was bad. Started it up and after a few minutes voltage dropped off under 12.

Was gonna post a link to this website. Hadn't seen anyone reference them in this thread yet. They have some good info on this page as well.

When running 200+ amp alternators it would be a good idea to upgrade.

As far as that wiring mod goes there was some big downside to it that Ed explained to me but I forget. I was thinking it had something to do with burning the glow plugs out faster due to excessive charging.
