Ah ha, you are correct. I'll try again tomorrow evening with the valves in the closed position.

Casey, It sounds like you have the valves open on your test gages, and the pressure is equalizing through the manifold. Make sure both valves on the manifold are tightly closed. They don't need to be open to read pressures. If the valves are closed. You should have a nice delta P across the compressor, assuming the compressor is turning, and not just the belt driven clutch pulley. If all the above is totally wrong, and the compressor is turning, it is probably bad.
