Becoming current in your electrical system A Nathaniel Hawthorne character in "The House of the Seven Gables" exclaimed: "Is it a fact — or have I dreamt it — that, by means of electricity, the world of matter has become a great nerve, vibrating thousands of miles in a breathless point of time?" Indeed, it's not a dream, and by the same hands of nature and science, we have airplanes that we need not start by hand and that may carry communication and navigation aids that would have boggled Hawthorne's mind. And yet what pilot hasn't stared out over a forest of circuit breakers, almost surely labeled in enigmatic abbreviations, and wondered aloud, "What in Ohm's law is going on behind the panel?" Though the idea seems straightforward enough — flip a switch and something happens — when something conks out or, worse, fails intermittently, the pilot's work load can take a turn for the worse.
