Electric fences are used to keep livestock safe from predators and ensure they don't escape. However, they can malfunction, leading to unintended escapes or shocks. To prevent this, it's essential to regularly test electric fences and address any issues. While some people use unconventional methods like touching the fence with their fingers or a blade of grass, these are unreliable and potentially dangerous. Instead, it's recommended to use tools like voltmeters, fence testers, or a compass to safely and accurately determine if the fence is functioning correctly. By investing in these tools and regularly maintaining the fence, you can ensure the safety and security of your livestock.

What You'll Learn
Using a voltmeter
To start, stand near the part of the fence farthest from the fence charger. Identify the ground wires of the fence by checking the fence manual. Hold the plastic part of the voltmeter’s probe and use the metal tip to touch the ground wire. If there is no ground wire, touch the metal tip of the probe into the soil near the fence. Keep the metal tip of the probe to the ground wire or the ground. At the same time, hold the metal prong on the end of the voltmeter to a charged wire.
The digital screen on the voltmeter will display the voltage. Compare the voltage reading to your fence manual, which will tell you what the fence’s voltage should be (most electric fences have a voltage of 2,000 to 10,000 volts). Repeat these steps along the fence, moving closer to the charger, to find weak spots.
If the reading is above or below the recommended range for your fence, there is a problem with it and it should be serviced. If you get a low voltage result, repeating the test closer to the charger may help you pinpoint where there is a problem. Even if the voltage reading is good, repeating the test in other locations will confirm the result.

Checking for vegetation
Vegetation, such as tall grass, branches, weeds, and bushes, can cause voltage leaks in your electric fence. Therefore, it is crucial to regularly inspect your fence for any plants that may be touching it. If you find any vegetation in contact with the fence, clear it away immediately. Additionally, maintaining a schedule of trimming plants near the fence is essential to prevent voltage leaks.
To check for voltage leaks caused by vegetation, you can use a voltmeter. Start by standing near the part of the fence farthest from the fence charger. Identify the ground wires of the fence by referring to the fence manual. Touch the meter's probe to the ground wire if there is one. If you are unsure or if there is no ground wire, skip this step and move on to the next step, which involves sticking the probe into the ground. Make sure you only hold the plastic or rubber section of the probe and not the metal tip.
If you are using a non-contact voltmeter, turn it on and wait for a blinking red light on the tip. Stand within 3 to 5 feet of the electric fence and point the blinking tip of the voltmeter toward the fence. The voltmeter may start to glow with a steady red light and beep, indicating a charge. If not, slowly move closer to the fence. If the non-contact voltmeter still does not light up or beep, there is likely no charge in the fence.
Alternatively, you can use a compass to check for voltage leaks. Hold the compass a few inches from each electric fence wire, being careful not to touch the fence. Hold the compass for about 30 seconds. If there is a charge, the compass arrow will vibrate.

Using a compass
To use this method, hold the compass near the fence, moving it within about 2-3 inches (5.1-7.6 cm) of each wire. If the wire is charged, the compass arrow will vibrate near the wires that have a charge. Hold the compass near each wire for 10-30 seconds. Electric fence chargers usually send pulses in 10-30 second increments, and these will have a more noticeable effect on your compass.
It is important to note that the compass needle will only move if the wire is carrying DC in one direction. AC at powerline frequencies reverses too quickly to visibly move a compass needle, and a multicore cable carrying DC in both directions will have little external magnetic field.
Additionally, if you are in a quiet area, you may be able to hear a faint buzzing or humming sound when the fence charger sends out a pulse.
While this method can be useful, it is not always accurate. For more reliable results, it is recommended to use an electric fence voltmeter, which is specifically designed to detect voltage in electric fences.

Indicator lights
If you do not already have indicator lights installed, you can purchase electric fence indicator lights from home improvement stores. They are a useful investment when installing an electric fence.
If you do have indicator lights, and they indicate that your fence is off, you can follow up with a voltmeter to see if you get variable voltage readings along the fence. This will help you identify if there is a weak spot in your fence.
In addition to indicator lights, you can also use a voltmeter to test the voltage of your fence. This is a more precise method of testing and will give you a specific voltage reading. You can purchase a voltmeter for $20-$50.
It is important to regularly test your electric fence to ensure it is working properly. Poor grounding is a major cause of electric fence malfunctions, so it is worth checking that your ground wire is connected properly.

Battery voltage
If your fence is battery-operated, non-solar, and DC-powered, you should also check your DC battery to ensure it delivers the appropriate charge. The outlet should be delivering between 105 and 125 volts to the charger. If it is underperforming, consult an electrician.
To test the voltage, you can use a voltmeter, which can be purchased for \$20 to \$50 at home improvement stores. Stand near the part of the fence farthest from the fence charger and identify the ground wires of the fence by referring to the fence manual. Touch the meter's probe to the ground wire, if there is one. If your fence has two or more wires, one of them is likely the ground wire. Use the owner's manual to identify it. If you are unsure or if there is no ground wire, stick the metal end of the probe several inches or centimeters deep into the soil. Ensure you do not touch the metal tip with your fingers during the test.
The digital screen on the voltmeter will display the voltage. Compare this reading to your fence manual, which will specify the intended voltage. Most electric fences have a voltage between 2,000 and 10,000 volts. Repeat these steps along the fence, moving closer to the charger, to identify weak spots.
