10 Most Common Electric Fence Problems, Part 2

In continuation to my previous post regarding common electric fence problems, here are two more issues to keep in mind.

#3 Lightning damage to a fence charger (Energizer): There is nothing more bothersome, than testing your fence the morning after a lightning storm and not getting a reading.  Trying to outsmart Mother Nature can be almost impossible, but there are a few tricks.  You cannot guarantee absolute lightning protection, but you can install safeguards such as surge protectors and lightning diverters to help avoid an expensive repair.  Installing a lightning diverter on your fence is not easy, but will relieve stress during those brutal storms.  The lightning diverter must have a separate ground bed 50’ from the energizer’s ground bed, with a minimum of one extra ground rod.  Lightning (electricity) is always looking for a ground.  Lightning diverters simply divert the lightning to ground before it reaches the energizer.  However, lightning diverters are not 100% of the fix. There are a lot of fence chargers on the market that offer a warranty that includes lightning damaged.  Kencove offers a low-impedance energizer line with a 3 year warranty that includes lightning damage.  If your energizer gets struck you can merely box up the pieces and send it to Kencove’s energizer repair station.  As long as the energizer was purchased from Kencove and is under warranty, Kencove is obligated to fix the fence charger or send you a brand new unit. Dean (Kencove’s Energizer Doctor) repairs all makes and models of fence chargers purchased from all farm stores. It is helpful to have a backup fence charger to use while the damaged unit is getting repaired. Kencove offers reconditioned energizers that would serve as excellent backup units in case of lightning damage.  While there is no way to completely avoid a lightning strike, we can be prepared.



#4 Bad Connections:  How many times have you walked your fence line and not been able to find the source of power leakage?  Sometimes it is not always obvious, and you must look very closely at your wire connections.  The best way to find a faulty connection is to use a voltmeter and test each side of the connection.  If the voltage decreases on one side of the connection, you have found the problem.  This connection will need fixed or replaced.  Connections can fail for a number of reasons; crimp sleeves crimped improperly or loosely, a hand knot that is making poor connection, rusty wires, or corrosion.  Be sure to focus on wire connections when building or fixing your electric fence, proper connections are essential to the flow of electricity.

    Have a zareba 6 joule, the unit snaps nice and loud with bright indicator light but zero output at the terminals.

      Hello Wayne, are you reading a voltage if you unplug both lead out wires and test the unit directly at the terminal? If you are reading under 6,000 volts at the terminal we recommend sending in your unit.

    Hi there, I just set up an open circuit fence about 150m long. The energizer is a Zareba Red Snap’r 66c. The energizer clicks loudly every couple seconds. There’s still voltage going through the line, but it a pulse, not constant. There is no short along the fence line (weeds, insulator connections etc), so I’m not sure why it’s releasing load. When I disconnect all the wiring from the energizer and plug it back in, it still does the same loud ticking which makes me think it’s the energizer itself that is faulty, not my wiring.

    Any ideas or advice?

      Hello Max, no worries sounds like your energizer is working correctly! Energizers do not constantly energize your wire, that would be very dangerous! Rather they set out pulse of voltage.

    Recently the fence quit shocking. I bought a new charger since the old one was 17 years old. If I just hook up the fence wire the charger appears to work. If I attach the ground wire it does not flash. I walked the fence and can’t see any problems. There is only one grounding wire that I see and the connections are good. It has worked for many years. Ideas?

      Hello Doug, what type of Fence Energizer do you have now?

    We are using power fencing syatem. Day time its working fine. But night time automatically voltage drop 6.6 KV to 1.5 KV. Afterwards its maintaining 1.5 KV. Please tell any solution for my problem. We changed Earth Pit. But no Result.

      Is there are a heavy weed load on your fence line? If so there is a lot more moisture in the evening and at night on the weeds that would cause a considerable drop in voltage.

    I have a herd of sheep . 2 strands test up to 7000 volts at both ends of the line. 3 tests show it is getting electric. But there is no shock to the sheep and my helper grabbed the line twice and held it…no shock. How can 3 diff. Tests show voltage going through wire, yet no shock ? I heard one sheep get zapped when it tried to pass through and the wire hit a t post. Surely this is a clue.

      It sounds like you are having a grounding issue. Is the ground frozen where you are located? Do the sheep have heavy wool? Wool acts as an insulator. Was you helper wearing rubber shoes?
      If the ground is frozen you will more than likely have to add more ground rods or create a posi/neg system. Check out this blog on Winter Grounding!
