Helps easily locate wire breaks. Temporarily replace your transmitter then
trace your fence configuration. Audible tones help discover each side of a broken
wire. Locates complete breaks only; partial breaks will not be detected by the
A: GENERAL DESCRIPTION OF OPERATION:
The wire-break locator is designed to find breaks in your boundary wire. This
is done by using the test transmitter, which transmits two different tones through
the boundary wire. On one wire there will be a low tone and on the other wire
there will be a higher pitched tone. The receiver is used to pick up these tones.
For example, if you are walking along the boundary wire and are hearing the
low-pitched tone, the volume of the tone will begin to decrease when you are
nearing a break in the wire. After you have gone past the break, the high pitched
tone will now be heard, in this way you can find the break within inches.
Step 1: Turn off your transmitter arid disconnect the boundary wires.
Step 2: Connect the boundary wires to the Test Transmitter.
Step 3: Grounding of the Test Transmitter- THIS IS VERY IMPORTANT. If not correctly
grounded, the Wire-Break Locator will not work properly and only one tone will
be heard. If your current transmitter is grounded in accordance with the instructions
supplied with your underground fence kit, take the ground wire from your transmitter
and attach it to the black Ground Terminal on the Test Transmitter. If your
current transmitter is not grounded, attach the enclosed wire to the Test Transmitter’s
black Ground Terminal and to a suitable earth ground (6 foot ground stake or
to the grounding wire for the house which is usually located near the electric
Step 4: Plug in the power adapter to the transmitter and then turn on power.
Step 5: Check to make sure there are batteries in the AM receiver.
Step 6: Turn the receiver on and tune it to approximately 530 khz. If there
is a station that can be heard then slowly turn the dial to an area where there
are no stations.
Step 7: To find the break in the wire, start by following the wire from the
transmitter out into the yard. Where the wire is twisted together you should
hear a combination of the two tones. Where the wire starts to go in two different
directions, start in either direction and continue to follow the wire. You should
now hear one of the two tones (orient the receiver in the direction in which
the tone is heard the loudest). Note: If there is a break in the twisted section
you may have to hold the receiver very dose to the ground and you will hear
only one of the tones. Where the wire begins to go in two different directions,
you will hear only one tone all around the boundary provided there is only one
break in the wire and it is in the twisted section.
Step 8: Continue to follow the wire until the volume of the tone begins to
decrease. You may now want to bring the receiver close to the ground and then
continue following the wire until the tone changes. The point where the tone
changes is where the break is located. If there happens to be multiple breaks
in the wire, the volume of the tone will decrease and then no tone will be heard.
Step 9: Repair the break in the wire by first stripping the ends of the wires
to be spliced. Insert the stripped ends into a wire nut and twist, then pull
making sure of a solid connection. Apply a waterproofing compound (like silicone)
in and around the wire nut. After the compound dries, you may also wrap the
wires and nut with electrical tape to prevent them from pulling loose and to
protect them from moisture. If there are multiple breaks in the wire then continue
to repeat Steps 8 and 9 until all breaks have been repaired.
Step 10: Hook up your original transmitter to the boundary wire and check that
the loop light is lit. If the loop light is not lit there maybe another break
in the wire. Continue to repeat the wire-break location tests until all breaks
have been found
and repaired. 400-277 REV A
Alternative Method for Finding Wire Breaks
1. Connect both ends of your twisted boundary wire to the first terminal on
2. Measure and cut a new piece of boundary wire that is 1/2 the length of your
3. Connect the new wire to the second terminal on the transmitter.
4. Locate the half- way point along your boundary loop.
5. Cut your boundary loop at the half-way point.
6. Connect the free end of your new piece of wire to either side of your boundary
loop at the half way point.
7. Turn the system on and check the range of this smaller loop with the receiver
8. If there is no improvement in the performance of your system, you may assume
that there is a break in this portion of your boundary. Because there is a small
chance you have more than one break in your loop, you should also try the same
procedure for the other side of your loop.
9. Once you determine a section of your boundary loop has a break in it, find
the middle of that section and cut the wire. Be sure to re-splice the first
cut that you made and make it waterproof by caulking with silicone.
10. Connect the new wire to your boundary loop at the point at which you made
the cut in STEP 9.
11. Turn the system on and check the range of this smaller loop with the receiver
12. Repeat STEPS 8 - 11 until you find the damaged section of wire.
13. Replace damaged wire with new wire. Remember that all wire in your boundary
loop must be the exact same size and type.
