How to Troubleshoot My Zareba A10

Keeping the livestock in while keeping out predators and unwanted trespassers is the general idea of a fence. Establishing this two-way protection with simple post and strand fencing can be somewhat challenging depending upon the size of the animal, the terrain of the pasture and the size of the area the fence must enclose. Ornery critters and determined intruders serve only to increase the burden on inadequate fencing. Zareba's electric fencing system provides a solution.

An electric fence must carry enough current to administer a change-of-mind jolt.
  1. Test the fence daily to make sure it is working properly. Check it twice daily, in the early morning and late in the day, to stay on top of any particularly lively animals you are raising.

  2. Much like this battery tester, the fence tester tells you how much current is on the fence.
  3. Test your fence by measuring the voltage in the section farthest away from the fence controller. Use an electric fence tester to get the readings for every area of the fence. Look for a reading of at least 2,000 volts to be assured the fence is in good shape.

  4. Push the probe of the tester into the ground 2 to 4 inches outside the fence line. Place the fence contacts on the fence wire and take a reading while holding the contacts to the wire. Double check any reading below the desired 2,000 volts.

  5. Accurate readouts from the controller tell you whether the section of fence is up to par or not.
  6. Test the fence controller next. Turn it off and disconnect the fence and ground wires from the ground terminals and the fence. Turn the fence controller back on while it is disconnected. Touch the ground probe and earth terminal together; then, touch the fence tester prong to the fence terminal. Check the controller reading to confirm it is working.

  7. Check the ground system of the fence. Lay a metal bar or rod against the fence 100 to 120 yards away from the ground rods. Force the probe into the ground, then touch the voltmeter to the ground rod.

  8. Voltmeters similar to this one tell you whether or not you may need additional ground rods.
  9. If the voltmeter reading is low (in the 400 to 500 volt range) strengthen the ground system by adding ground rods 10 feet apart connected with a single ground wire. Check the volt range after installing the extra ground rods.

  10. Continue daily or twice daily monitoring of the entire fencing system after you have shored up and evened out voltage readings on the entire fence. Keep an extra fence controller on hand to avoid any extended outages.


  • Keep insulators cleared of spider webs and accumulated dust or dirt.
