Sullivan argues that with electrical systems, asking what is wrong leads to thousands of possible answers. By asking what is (e.g., "Does this relay have power?"), you systematically isolate the fault by process of elimination, quickly reducing the 99% of the circuit that works to find the 1% that has failed.
