HELP, Wife came home said message board said battery volts 10.8
I ran codes none came back as other than history but on start up then rerun a code # came up 321111 but will not come up agine.
No noise from alt.,or adjuster just shows voltage is runing below 11 volts.
I replaced battery witha red optima on 8/2003

Any one have any ideas as to what to do next.

Take the battery to a pep boys or other service center to test under load. If the battery checks out, then look at the alternator

There's been quite a few Optima early failures lately. My guess is that this is another one. I'd remove it and have it load-checked. You might want to have this done where it was purchased so that they can replace it under warranty.

Good luck.

I did take the car to have battery load checked and it came up good ??
I took the car to chevy dealer this AM and found out it was the Alt. it had a bad diode.
Whats up with Delco parts this is the 3rd 1 in this car.
glad it was a covered part with a lifetime warranty.
