Testing Electric Fences: A Safe Way To Protect Your Horses

how to test a horse electric fence

Electric fences are often installed to keep horses and other livestock protected from predators. However, it is important to test your electric fence to ensure the voltage is not too high or too low. While it may be tempting to test an electric fence by touching it, this is not recommended. Instead, you can use a voltmeter to measure the voltage. A voltmeter can be purchased at most home improvement stores for $20 to $50. To use a voltmeter, stand near the part of the fence farthest from the fence charger and identify the ground wires of the fence by checking the fence manual. Compare the voltage reading to your fence manual to ensure it is within the correct range. Repeat these steps along the fence, moving closer to the charger, to find any weak spots.

Wear protective clothing, such as rubber gloves and shoes, to avoid shocks

When testing an electric fence, it is important to wear protective clothing to avoid shocks. Rubber gloves and shoes are recommended to minimise the risk of accidental shocks. This is especially important if you are using your hand to test the fence for a current, which is not recommended as it can be dangerous and may cause your muscles to spasm, making you unable to let go of the fence.

There are other safer methods to test an electric fence. One way is to use a voltmeter, which can be purchased for $20 to $50 at home improvement stores. To use the voltmeter, stand near the part of the fence farthest from the fence charger and identify the ground wires by checking the fence manual. The digital screen on the voltmeter will display the voltage, which you can then compare to the fence manual to ensure the voltage is not too high or low.

Another option is to use a non-contact voltmeter or voltage tester, which can be purchased for $20 to $30. To use this tool, stand within 5 feet of the electric fence and point the blinking tip of the voltmeter towards the fence. If the voltmeter glows with a steady red light and beeps, this indicates a charge.

By wearing protective clothing, such as rubber gloves and shoes, and utilising safer testing methods like voltmeters, you can effectively test an electric horse fence while minimising the risk of shocks.

Keep vegetation near the fence trimmed to prevent voltage drainage

Keeping vegetation near an electric fence under control is essential to prevent voltage drainage. Weeds, grass, and other plants that touch an electric fence can cause voltage loss and render the fence useless. To avoid this, it is necessary to regularly trim the vegetation along the fence line.

One way to effectively manage vegetation is to use a low-profile fence mower specifically designed for clearing fence lines. This option is ideal for those with large fence lines of several miles. Alternatively, a sharp scythe can be a quieter and more efficient tool for trimming under fences, especially if there is ample space between the bottom wire and the ground.

For smaller operations or tighter spaces, a hand-held flame weeder can be used. These devices apply heat to plants, causing their cells to burst and denaturing leaf proteins. While effective, flame weeders may not be suitable for drought-prone areas.

Another organic method to block weeds is to install a narrow band of weed cloth under the fence line and cover it with gravel. Additionally, leaving grass along the fence line at three inches or higher can help weaken weeds by shading them out.

By implementing these vegetation control methods, you can help prevent voltage drainage and ensure the optimal functioning of your electric fence.

Use a voltmeter to measure voltage

Using a voltmeter is one of the most reliable ways to test an electric horse fence. You can purchase a voltmeter from most home improvement stores for $20 to $50.

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. 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.

You can also buy a non-contact voltmeter, or non-contact voltage tester, for about $20 to $30 at most home improvement retailers. They’re easy to use and won’t require you to touch the fence wires. Turn the non-contact voltmeter on and wait for a blinking red light on the tip. Stand within 5 feet of the electric fence. Point the blinking tip of the non-contact voltmeter toward the fence. The voltmeter may begin 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 doesn’t remain lit up or beep, the wire likely lacks a charge.

It is important to always wear proper attire while testing your fence. Just in case you make contact with the fence, rubber gloves and shoes will help to minimize the risk of an accidental shock.

Check for shorts in the fence after rain

After heavy rain, it is important to check your electric horse fence for shorts. Heavy rain can cause plants to come into contact with the fence, which can cause a short circuit and damage the fence and battery. Therefore, after rainfall, you should check along the electrical fence for any plants or particles that have come into touch with the electric fence wires. If you discover something tangled in the fence, turn off the fence by disconnecting the power supply at the electric fence charging station. Wait a few minutes before touching the fence to ensure it is no longer dangerous, then remove any plants or debris that came into contact with it.

In some cases, you can simply remove particles by hand, but sometimes you will need tools. Heavy rains can also bring down large amounts of water that may carry tree branches, so be sure to check for these larger items as well.

Other things to check for shorts in the fence after rain include:

  • Check that the wire is not touching a fence post anywhere along the fence. If your wire comes into direct contact with a fence post, it will short out.
  • Check for good connections around your gates. Electrified gates can lose connection over time, and insulated wires running under non-electric gates may deteriorate.
  • Check for damaged insulators. Insulators are important for containing the voltage in the wires, but a damaged insulator can cause a leak.
  • Check that you are using the correct insulators for your fence. Using the wrong insulators can cause shorts.
  • Check for sparks from your electric fence, which could be another indicator that it's shorting out. Sparks can be caused by grass or particles touching the fence, especially if the vegetation or debris are moist.

Ensure your horse knows the fence boundaries

Electric fencing for horses is a safe, practical, and cost-effective way to ensure your horse knows its boundaries. The mild electric shock the fence delivers is harmless, but it does deter horses from pushing against or crossing the boundary. Horses will remember the shock and will learn to keep a safe distance from the fence, forming a psychological barrier.

To ensure your horse knows the fence boundaries, you should first make the fence visible to your horse. Horses can't easily see the strands of wire, so placing flags or tape at regular intervals along the fence will help them to see it and avoid it. This is a vital step to reducing the possibility of injury.

Next, lead your horse slowly around the perimeter of the paddock with the power off. Take your time with this step, ensuring your horse gets acquainted with the new boundary fence. Once you have done this, turn the power on and allow your horse to explore the paddock independently. It is important to allow your horse to investigate the fence alone and to observe them getting a shock. They should then recoil from the fence and keep their distance.

If you plan to keep multiple horses in the paddock, repeat this process with one horse at a time. It is also important to place warning signs indicating electrical activity at regular intervals, especially if your fence is accessible to the public.
