ABSTRACT:
Wire identifying apparatus for identifying wires of a multiple wire electrical system as the wires extend between one location and another, said wire identifying apparatus comprising two separate units for use at the two locations, respectively, and designated herein as Unit No. 1 and Unit No. 2, Unit No. 2 having a plurality of terminals for connecting to one end of the wires to be identified and having a ground terminal, Unit No. 2 also having an array of resistors connected in parallel circuit with each other between the ground terminal and the other terminals, there being a different resistor corresponding to each of the other terminals, Unit No. 1 having a plurality of terminals for connecting to the opposite end of the wires to be identified and having a ground terminal, Unit No. 1 also having electrical circuitry including a selector switch having multiple positions corresponding to the number of terminals on Unit No. 1 and a multi-digit read-out display and such that, when the selector switch is moved from terminal to terminal on Unit No. 1, the numbers assigned to the wires on Unit No. 2 will read out on the digital display of Unit No. 1.
