Shorted wires will cause a breaker to trip. Disconnect the

wires, and make sure the ends of the wires on both sides

of the cable are isolated from each other and other wires

or loads.

Interconnect ten (10) 9V batteries in series, by connecting

negative “-“contact of one battery to the positive “+” on

the other one. The 10 batteries will create safe 90V DC

power source.

Connect the circuit as shown in the illustration below.

AT-7000-T

Setup the receiver to Energized TIP SENSOR mode. Start tracing the cable until you find the

location where the signal stops. To verify the place of the fault, move the transmitter to the

other end of the wire and repeat tracing from the opposite end. If the signal stops at the

exact same location you have found the place of break.

Note: This method will be affected by signal cancellation effect. Expect a very weak signal.
