What You'll Learn
Clicking noise may indicate a problem with the output voltage
A clicking noise coming from your electric fence may indicate a problem with the output voltage. This issue can arise due to various factors, and there are several troubleshooting steps you can take to identify and address the problem.
Firstly, check if the charger is properly connected to a functioning power outlet and ensure that the fuse is not blown. If the power source is functioning correctly, the issue may lie with the internal components of the charger, which may require professional repair.
In some cases, a clicking noise can be caused by a short circuit. To investigate this, disconnect the charger from the fence and use a multimeter to test the output terminals for continuity. If a short circuit is detected, carefully inspect the fence line for any damaged wires or vegetation that could be causing the issue. Ensure that the fence is not touching any metal objects or the ground, as this can result in arcing and affect the voltage.
Additionally, it is important to check the grounding system. Make sure that the grounding rods are properly installed and have good contact with the soil. Poor grounding can lead to a lack of electrical flow through the fence, resulting in clicking noises and reduced effectiveness.
If you have recently set up your electric fence, ensure that the ground rods are installed at the correct depth. In some cases, you may need to daisy-chain multiple ground rods to achieve the appropriate charge. Pouring water around the ground rods can also help improve the ground contact and potentially resolve clicking issues.

Clicking could be caused by a loose connection or a short circuit
Clicking in an electric fence could be caused by a loose connection or a short circuit. A clicking noise coming from your fence charger may indicate a problem with the output voltage. If your fence is not powering on, the first step is to check the power source. Ensure that the charger is properly connected to a functioning outlet and that the fuse is not blown. If the power source is not the issue, it may be a problem with the internal components of the charger that require professional repair.
If you suspect a short circuit in your fence charger, start by disconnecting the charger from the fence. Then, use a multimeter to test the output terminals for continuity. If there is a short circuit, you will need to inspect the fence line for any damaged wires or vegetation that may be causing the issue. A short circuit can also be caused by the fence touching something metal, or even just being close enough to arc.
To troubleshoot a loose connection, you can try pouring water around the ground rod and seeing if you still have the same problem. You may also need to add more ground rods. Ensure that your grounding rods are properly installed and making good contact with the soil. Poor grounding can result in a lack of electrical flow through the fence.
It is also important to check that your fence is properly set up and that there are no sagging or ripped sections that may be touching the ground. This can cause the fence to ground out, resulting in clicking noises.

Low voltage in wires and arcing at the ground rod
If your electric fence is making a clicking sound, it could be due to low voltage in the wires and arcing at the ground rod. This can be caused by several factors, including:
- Inadequate grounding: The ground rod may not be installed deeply enough, or there may not be enough ground rods in the system. It is recommended to have at least three ground rods, and they should be placed in moist soil if possible as it conducts electricity better than dry soil.
- Faulty insulators: Check for cracked or faulty insulators as this can cause arcing and voltage loss.
- Interference: Electric fence problems can also be caused by interference from electric or telephone ground systems. Ensure your ground system is at least 33 feet (10 meters) away from these systems.
- Vegetation: If there is vegetation growing around the fence, it can cause arcing and short-circuiting, especially if the vegetation is wet.
- Weather: Dry, sandy, or rocky soil can hinder the performance of your electric fence. Ensure that the ground around the ground rod is moist.
- Charger issues: The fence charger may not be powerful enough for the length of the fence, or it may be faulty and need replacement.
To troubleshoot low voltage and arcing issues, you can perform the following steps:
- Check the depth of the ground rod and ensure it is at least 5 to 6 feet deep.
- Test the voltage at the ground rod using a voltmeter. If the reading is higher than 0.3 kV, add more ground rods or relocate your ground system.
- Inspect the insulators for any cracks or damage and replace them if necessary.
- Keep vegetation around the fence trimmed to prevent arcing.
- Ensure your charger is powerful enough for the length of the fence and consider investing in a lightning arrester to protect against lightning strikes.

Faulty fuse or power source
If your electric fence is clicking but not working, it could be due to a faulty fuse or power source. A clicking sound indicates that the energizer is trying to generate electric pulses, but there could be an issue with the power supply that is causing a weak or non-existent charge.
Fuses and circuit breakers are crucial safety measures that protect the energizer and the overall fence system from potential overloading or short circuits. If these mechanisms fail and the fuse blows, it means that the electrical current has exceeded the system's capacity. A blown fuse will cause the fence to lose power, so it is important to check the fuse if your fence is not working. In some cases, the fuse may need to be replaced.
To determine if the power source is the issue, you can perform a few diagnostic tests. If your fence is plugged into an outlet, try plugging in another electrical device, such as a light, and check if it works. If the other device does not power up properly, consult an electrician as there may be an issue with the outlet. For solar-powered fences, use a voltage tester to measure the battery voltage. If it is underperforming, the battery may need to be replaced. Solar batteries typically last about 1,000 days (3 years) and can lose their charge after extended periods without sunlight.
If you have a battery-operated, non-solar, DC fence charger, check your DC battery to see if it is delivering the appropriate charge. The battery may have been drained by a short somewhere along the fence or by animals frequently testing the fence. Before reconnecting the battery, be sure to check for shorts. You can also test the terminals, which are the posts used to attach the hook-up wires to the energizer, to determine if the energizer is properly outputting energy.
In some cases, a clicking electric fence may be due to factors other than a faulty fuse or power source. For example, vegetation touching the wires, faulty or broken wires, or poor connections can create electrical resistance and interrupt the circuit's continuity. It is important to regularly inspect the fence line and maintain the insulators to prevent unintended contact that could lead to short circuits.

Faulty charger
If your electric fence charger is clicking, but not flashing, or if it is clicking and the light is not coming on, this could be a sign of a faulty charger. A clicking sound is normal for a fence charger, but if the fence is not working, there may be an issue with the charger.
Firstly, check that your charger is properly connected to its power source. If it is a plug-in charger, try plugging another electrical device into the outlet and see if it works. If not, consult an electrician. If your charger is solar-powered, check the battery voltage with a voltage tester. If it is underperforming, you may need to replace it. Solar batteries last about 1,000 days, after which it is advised that you obtain a new one. Solar batteries can also lose their charge after an extended period without sunlight.
If your charger is connected to a power source and you are still experiencing issues, try the following:
- Disconnect both hook-up wires from the charger, then turn the power back on and check the voltage output with a voltage tester. If the voltage is under 2,000 volts, there is a fault in the energizer.
- Check the connections (positive-to-fence and negative-to-ground rod) and make sure they are securely attached. If they are loose, reattach them, turn the power back on, and see if this resolves the issue.
- Keep the hook-up line connected to the terminal and disconnect it from the fence (leave the ground rod hook-up attached). Turn the power on and check the output of the hook-up wire that is normally attached to the fence.
- Test your ground system. The ground system should be at least 33 feet (10 m) away from electric or telephone ground systems to avoid interference. In dry weather, wet the area around the ground system to keep the soil moist. Make sure there are a sufficient number of ground rods—at least three. Use a digital voltmeter to measure the fence voltage. It should read 2 kV or less. If not, add more ground rods.
- Use a fault finder to locate a fault in the fence. Starting at the lead-out wire, work your way along the fence, taking readings at regular intervals. A fault will show up as an abnormally high reading.
- Check for shorts in the fence. This can be done using a Fault Finder, Smart Fix, or Fence Compass tool.
- If your fence charger is equipped with a performance meter, use this to troubleshoot the fence line.
