Great, something less to worry about. Glad you figured out that the alternator is the problem, just for the hell of it double check the batteries before the new one goes back in.

Ed @ FICMrepair.com makes and sells upgrade battery and alternator cables.
1. Add a heavy cable alternator to ground.
2. Add heavy cable w/300 amp fuse alternator to pass battery.
3. Add a heavy cable between pos terminals of batteries.
These reduce resistance between key components of electrical system to maximize charging and reduce voltage drop.

Did you have those batteries re checked? Are all your connections solid and free of rust, paint etc.?
It is possible they have a batch of bad alternators going out. This happened to me with back to back bad alternators from DC Power.

I'll have the batteries tested again tomorrow. All connections are good. How many alternator did you go through till you got a good one?

The Owner yes Owner of DC Power called me and stated they had a bunch of defective rectifiers I believe (it was a part made by bosh) were all defective.

Dang that stinks. I sat at pretty much +14V all day driving with AC, radio on, and iPads or something else plugged in and charging...we drove 12hrs today and I was monitoring temps and voltage regularly.

Just came back from O'Reilly s. They hooked up their alternator and battery tester. Batteries tested good. It said voltage regulator is bad. Second alternator in a row out the door from DB Electrical defective.

valutechpc: Maybe you could request your money back from DP and purchase one from here. http://alternatorparts.com/6g-series...lternator.html
Last November I had to replace my Alt & purchased the 160A alt from this site after finding and reading about it in the 1999 - 2003 7.3L Powerstoke Diesel Forum (1999 - 2003 7.3L Power Stroke Diesel - Ford Truck Enthusiasts Forums). It worked right out of the box.

Yes I have considered them. They are a little more expensive. DB sent me a refund on the first one without any explanation even though I asked for a new one or to repair that one. When I asked for a tracking number for the replacement I got no response.
