I have about 5 acres in an invisible fence for my dogs. It is not buried but just laid on top of the ground, but several years worth of leaves have covered the wire. It is no longer giving a signal even with new collar batteries. Is there any inexpensive way to find out where the break in the line is? I can't visually find all my connectors. Thanks, Ann S

I have no specific experience in doing what you are asking, however, I like to try to solve problems and since no one has posted a response let me have a go at it.

Extech DV30 AC Voltage Detector - instrumart.com

This voltage detection device seems to operate at low voltage (down to 12v AC). Safety is of course a concern so you must act accordingly. If you get a low voltage energy limiting transformer, like the ones that are used in your furnace to supply voltage to the thermostats, then this can act as a source of safe low voltage.

So the plan would be to:

-1- purchase this or a similar low voltage detection device.
-2- purchase a 24vAC energy limiting transformer
-3- have someone who is capable of wiring electrical devices disconnect the invisible fence wire from the system
-4- safely connect the 24vAC supply to the invisible fence wire with one end also connected to earth ground (get an electrician if you don't have the experience).
-5- then, staring on the hot side of the circuit (the one not connected to earth) walk out half way and find the fence wire and see if voltage can be detected.
-6- if not, the break is before that, so divide that first half in half again and repeat -5- and -6- until you find the break.

I hope this helps or at stimulates someone who has done this before to supply a more refined solution.

Be well.

I forgot to list the last steps:

-7- after finding the break, disconnect the 24 VAC
-8- then fix the break
-9- then reconnect the fence wire and re-test the system
-10- if OK emit a little "woo who" :)

Be well

Seems to me the easiest thing to do would be to rake the leaves away to find and expose all of the connectors and restore the signal?
