Battery Voltage when load button is pressed: 12V
Car has not been driven in two weeks and I leave the terminals disconnected for fear of discharge, except the last 2 days when I have been doing these tests.
Thanks

This just verified the (-) cable connection to your battery seems to be OK (corrosion problem area).
What is the voltage across the battery, motor running at idle, when you have all accessories (lights, radio (is it working?), AC, fan) turned-on?. As JFP mentioned earlier, it should not drop to 12.03 volts, that is an indication the alternator is bad. Did Pep Boys perform a load test on it?
