Things You'll Need
- 100 RF Choke
- AM radio
- Screwdriver
Instructions
Purchase a 100 RF choke from a hobby or electric supply store. You will also need a radio capable of receiving AM band frequencies. Tune the radio to 600 mhz.
Unplug the power cord of the underground fence power supply. Use a screwdriver to loosen and disconnect the wires leading to the fence from the power supply.
Connect the ends of the RF choke to the terminals where the fence leads were attached. There will be a lead on each end of the choke. Connect one lead to one terminal and the opposite lead to the other terminal.
Turn the adjustable transmitter strength to full. The power supply should not indicate a break at this point. Connect the fence leads to the ends of the RF choke. Connect one wire to each end of the RF choke.
Turn the volume of the AM radio up and walk along the fence line. You will be listening for a throbbing sound that will indicate the underground line is intact. When the throbbing stops this will indicate a break in the line.
