How to Test Your Electric Fence Energizer

We are quickly going to look at fault-finding  on an electric fence energizer. Let’s see what happens if we switch it on. You’ll see in this instance the alarm is going off. What I’m going to show you is how to test whether the fault is on your energizer or on the fence.

Testing Your Electric Fence Energizer, the How

So, if you look at the bottom of the energizer – in this case we are using a single zone energizer – you’ll see there are three wires coming in. One is the earth wire and then there are the two live wires on the other side. I’m going to have a look that it in more detail shortly. Now I have taken off the cables that I was just showing you a minute ago and what I’m going to do now is to test whether the energizer works. Basically what we’re doing is taking the live wire of the fence and make a small fence; so it’s going be one little wire and we are going to screw it into here.  If you look at the connections now, you can see the output of the live fence wire here, where it is red; then below it, the return of the live fence wire to the energizer. The earth wire is on the left hand side. Now that we’ve connected our test wire, this represents our electric fence. We know for sure this mini-electric fence wire is not touching the earth wire and neither is it broken at any spot. Then we’re going to switch on the energizer and check what happens. So, I go back to the energizer. I’ve got my little tag and, yes, you see it’s working normally. The energizer is working fine, so, because we had an alarm condition, there is something wrong with the fence.

Testing the Electric Fence Alarm

Another thing we can do is we can do a test to see if the alarm works when there’s a short on the fence. This would be similar to someone breaking into the property. For this you must be careful not to physically touch the wires, so you need to use an insulated screwdriver. To test, we touch the earth and live wires together. Then you’ll see the alarm condition going off and so we know the energizer’s alarm is functioning properly. Let’s switch it off and if we switch it on again you’ll see it works properly.   See other videos on Electric Fences.
