Jäger,

Did as you suggested. All tests with (-) connected to chasis. Here are the results:
Battery Voltage with car sitting overnight: 12.2v
Battery Voltage when car is started up: 13.8V(hovers between 13.7V and 13.8 V now)
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
