An aircraft instrument includes an engine display area providing aircraft engine parameters simultaneously with an electrical system display area that selectively provides one of a plurality of aircraft electrical system parameter displays. In the event of an aircraft electrical power supply failure, the instrument may be automatically powered by otherwise unused energy safely harvested from one or all magneto P-leads of an aircraft via an energy harvesting circuit.
