How to troubleshoot electric fence problems

Troubleshooting an electric fence can be a challenging task, but with the right steps, you can identify and fix the issues efficiently. It is essential to regularly check your fence's voltage using a volt meter or a five-light fence tester. If you notice a significant drop in voltage, follow these steps to diagnose and resolve the issue.
The first step involves examining the fence controller. Some controllers come with fuses that can be replaced if needed. If your fuses are blown, replace them with "1 amp/250V" fuses. If the fuses are fine but the controller still doesn't operate, proceed to the next step.
Secondly, check the power source. Depending on whether your fence controller operates on 115VAC or uses a 12-volt or 6-volt battery, ensure the power source provides the required voltage. Remember to disconnect the battery clamps or unplug the controller before testing.
Next, check the fence controller's output. You can use a volt meter or a screwdriver to draw an arc between the hot terminal and the ground terminal. The length of the spark gap varies depending on the type of fence controller you have. If the output is too low, consider getting your fence controller serviced.
Lastly, if the fence controller output and power source are normal, inspect the fence installation. Reconnect the hot lead-out wire, disconnect all fences running off the main fence, and check the voltage. If the voltage drops drastically or the fence shorts out completely upon connecting a certain fence, you've found the problem area.
Once you've identified the problematic fence or section, inspect it closely for shorts. Pay special attention to corners, gates, and places where the fence is close to others. Also, inspect insulators and connections carefully. If you hear a snapping sound, it might indicate electrical shorting.
Also, remember that vegetation or rust on the fence can cause voltage loss. To prevent this, consider spraying herbicide under the fence and replacing any rusty wire. By following these steps, you can maintain the performance of your electric fence and keep your livestock secure.
