What You'll Learn
- Use a non-contact voltmeter to check for a blinking light and beeping sound
- Move closer to the fence if the voltmeter doesn't light up or beep
- Check the entire length of the fence for problems
- Use an electric fence voltmeter for specific voltage readings
- Call an electrician if you get variable readings or don't have a voltmeter
Use a non-contact voltmeter to check for a blinking light and beeping sound
To check an electric fence with a non-contact voltmeter, start by standing within 3 to 5 feet of the fence. Point the blinking tip of the voltmeter towards the fence. The voltmeter may begin to glow with a steady red light and beep, indicating a charge. If this does not happen, slowly move closer to the fence. If the voltmeter still does not light up or beep, the wire likely lacks a charge. Repeat this process along the entire length of the fence to check for faulty wires.
Non-contact voltmeters are very simple tools, but you should always read the product instructions before using one for the first time. They are typically the size and shape of a fat Sharpie, and the detection occurs at the probe tip, which is designed to be pushed into an outlet. They are useful for troubleshooting or installing a dimmer switch, for example.
Before using the tester, check its batteries by holding it against the cord or bulb of a lit lamp. You'll hear continuous chirps or see a series of flashes to confirm the tester has detected voltage.
Non-contact voltmeters do not give you any information about the amount of voltage; they only reveal if there is or isn't any voltage in the fence. If you want specific voltage readings, use an electric fence voltmeter.

Move closer to the fence if the voltmeter doesn't light up or beep
If the voltmeter doesn't light up or beep, it's recommended that you slowly move closer to the fence. However, it's important to never touch the fence wires with your hands. If you're using a non-contact voltmeter, you can move within a few inches or centimetres of the fence wires. If the voltmeter still doesn't light up or beep, you can be confident that there isn't any voltage in that area. Repeat these steps along the entire length of the fence to check for faulty wires.
If you're using a screwdriver with a plastic handle as an alternative testing method, gently move the screwdriver along the wire for up to 30 seconds. If no arc occurs, the wire likely lacks a charge.
If you find that there are faulty wires or weak spots, you can begin troubleshooting to get your fence back up and running. Separate the fence into sections, then progressively reconnect and check the voltage as you go. When the voltage drops, you've identified the problematic section. With the energizer connected and turned on, follow the direction of the current to find the leak.
It's important to regularly test your electric fence to address issues promptly and prevent livestock from escaping.

Check the entire length of the fence for problems
Checking the entire length of an electric fence for problems is an important step in ensuring the reliability and safety of the fence. Here are some detailed instructions to help you through the process:
Firstly, it is crucial to prioritize your safety. Before beginning any troubleshooting procedures, disconnect the power source to the electric fence to eliminate the risk of electric shock.
Now, let's begin checking the fence for any issues. Start by standing near the section of the fence that is farthest from the charger, which is usually a small box that provides electricity to the fence. The charger can be identified by referring to the fence manual or looking for a small box-like structure.
If you are using a voltmeter, hold it within a range of 3 to 5 feet (0.91 to 1.52 meters) from the fence. Point the voltmeter at the fence constantly or at intervals of about 50 to 100 feet (15 to 30 meters). If you are using a non-contact voltmeter, look for indicators such as blinking lights and beeping sounds, which suggest the presence of a charge. Move closer to the fence if you do not detect any indicators initially.
As you move along the fence, repeat the test at regular intervals of 100 feet (30 meters). This helps to confirm the results and pinpoint any specific areas with low voltage or other issues.
While performing these tests, keep an eye out for any visible damage or breaks in the fence. Inspect the fence line for grounding faults, insulator issues, and loose wire connections. Ensure that the hot wire is not touching any fence posts, woven wire, or other objects. Look for cuts or worn areas in the line, especially if you are using polywire.
Additionally, check the ground rods and their connections for any damage or corrosion. The ground rods should be deeply installed into the ground, ensuring good contact with the earth for proper grounding. If the weather has been dry, consider pouring water around the grounding rods to improve conductivity.
By following these steps and regularly checking the entire length of the electric fence, you can identify and address any problems promptly, ensuring the fence's effectiveness and maintaining the safety of your livestock or property.

Use an electric fence voltmeter for specific voltage readings
Electric fence voltmeter are designed to detect voltage in electric fences, making them a reliable tool for the job. Most models include a handheld meter with a digital readout, a metal prong on top, and an attached metal probe at the end of a wire. Before using the voltmeter, ensure that it has a battery installed and push the button to turn it on. You'll see a blinking light (usually red) at the tip of the meter, indicating that it's on and ready to use.
To test your electric fence, start by moving to the section of the fence furthest from the charger, as this is where you can be most confident that the proper voltage is coursing through the fence. The charger, usually a small box, provides electricity to the fence. Refer to the owner's manual or signage on the charger to determine the correct voltage range for your fence. Electric fence voltages typically range from 2,000 to 10,000 volts, depending on the type of animals they are meant to control.
When you are within 3 to 5 feet (0.91 to 1.52 meters) of the fence, point the meter at it constantly or at intervals of around 50 to 100 feet (15 to 30 meters). If you get within a few inches or centimeters of the fence wire(s) and the meter doesn't light up and beep, there is no voltage in that area. However, if you get the "on" indicator (lights and beeping) in some sections and "off" in others, you may have variable voltage readings along the fence.
In such cases, an electric fence voltmeter can provide specific voltage readings. Move along the length of the fence, taking measurements at regular intervals. This will help you identify areas with lower or higher voltage and make any necessary adjustments to ensure the fence is functioning effectively and safely.
