ABSTRACT:
Apparatus for locating a conductor or a short circuit in the wiring of a AC or DC circuit is disclosed. The apparatus is portable and useful in the troubleshooting of complex control systems or the like with the aid of a clamp-on ammeter. Typically, the apparatus is connected in the fuse circuit to be tested, and a pulsating current of low pulse rate is supplied by a solid-state relaxation oscillator which opens and closes a relay bridging the fuse terminals or other convenient circuit point. Where the fuse circuit to be tested is a DC circuit and both AC and DC circuits are in a common conductor bundle, a separate astable multivibrator acts to supply a higher frequency pulsating current superimposed on the low pulse rate pulsating current. The location of a particular conductor or a short circuit is then easily found with the aid of a clamp-on ammeter.
