ABSTRACT:
A method for isolating a fault in an aircraft circuit having a lead conductor and a plurality of branch conductors coupled to the lead conductor is disclosed. The method includes coupling a reference line of a device to a ground of the lead conductor, coupling a supply/return line of the device to the lead conductor, supplying an impulse signal to the supply/return line, and receiving a reflected signal that is produced from the impulse signal. The method also includes determining whether a fault exists in the plurality of branch conductors using the reflected signal, coupling the reference line of the device to a ground of the plurality of branch conductors, coupling the supply/return line of the device to one of the plurality of branch conductors, and supplying a signal to the supply/return line.
