Here are a few more bits of info from our charging issue

1) started the car at idle voltage across the battery was 12.03 in the hatch and 12.5 at starter selenoid.

2) At 3K RMP voltage readings didn't change.

3) Under load with lights, fan etc on voltage dropped below 12volts.

4) With the car idleing, removed positive lead from battery, car still ran. Voltage at the starter selenoid was 14.3. This is where it should be with the battery hooked up.

Does anyone have any other ideas or comments on this new info?

Thanx in advance for your input.
