#4. How to Find a Broken AC Underground Wire with AM Radio
Putting up a physical fence for your pets is expensive and the sweet alternative is always the use of an invisible electrical fence.
When you buy an invisible dog fence, you receive a transmitter along with it. The transmitter is always silent but it starts beeping when it detects a fault with the underground wires.
The first step when using an AM radio is to confirm that the beeping isn’t from a faulty transmitter. To do this, you should disconnect the two wires that run from the transmitter to the fence.
Replace with other small wires. After disconnection, if the transmitter continues beeping, then you have a damaged transmitter. However, if after disconnecting the wires leading to the invisible fence the beeping stops, then you could have a broken underground wire.
Now, pick the two wires that you disconnected from the transmitter- the ones leading to the fence. Connect the wires to an RF choke and insert the leads of the RF choke to the jacks of the transmitter where the two wires are connected originally .
This process helps the transmitter to continue sending signals to the fence even with the breakage on the underground wires.
Now, pick the AM radio receiver from the collar of your dog and walk with it along the perimeter of the fence. Make sure that the radio transmitter has the highest frequency setting as you walk along.
If the fence is live, the radio receiver should produce a beeping sound. When you approach an area and the beeping stops, then you’ve found your break and it’s time to fix it.
Conclusion
In a nutshell, finding broken wires buried underground isn’t easy especially if there are no markings to show the perimeter.
This guide details how you can use an AM radio on your dog fence, or unearth a broken ac wire through digging, and above all using a wire locator.
Good luck with locating your wire break!
