If I just wanted to test the effect of the alternator on fuel economy, could I just disconnect that big alternator cable?
you're alternator should have some smaller wires plugged into it somewhere. Those wires comprise the field circuit. The field circuit is what "powers up" the alternator. If you break the field circuit, you turn the alternator off. When you complete the circuit, the alternator resumes its normal functioning.
