Charging System problem?

Charging System problem?
In the last week, I've replaced the alternator and battery in my 2002 Z06. DIC read 12.9 volts after I dropped the new battery in, and car ran fine. This morning (1 week later)...the DIC read 12.2 when started, then 12.1, then 12, then 11.9.... What could possibly be wrong here??
Thanks for your advice!

Welcome to the club.
Similar thing here. http://forums.corvetteforum.com/show...767&highlight=
Having changed out everything I can think of, I am now looking to the alignment of the planets as a possible cause
I was reading 11.9V today on the DIC, which I have now proven is always off by .5V, but still not sure why my voltage is fluctuating when I come to a stop. Also seems to pick a different range to swing in every time I get in the car?
I have probed the car with the multimeter so many times I have having to start using Vaseline or it squeaks at me!

Hi There,
Is your alternator a new or rebuilt one?Most of the time rebuilt items are not bench tested or incorrectly reassembled & your car is the first test the alternator sees.Do a voltage test on the alternator. If it tests ok then have the battery load tested.

There is a ground connection between the battery and the engine fuse box, mounted to the frame down in there. If I understood a post by Bill Curlee, thats where some issues with battery voltage happen if all the other things have been tried as mentioned above.

Hi, g104 located on the pass side frame rail under the battery box.
