In spite of having a well constructed electric fence which follows, in most
part, all the rules, I do have my periodic battles with it.
I was very interested to read here that using plastic hose pipe as an
insulating barrier may not be the best idea in the world. There are a few
places throughout my fence line where the use of plastic hose was the only
thing I could think of to separate the hot wire from metal standards, such as
when the wire was actually passing through the groove on the top of a steel
Waratah. There is an insulator especially made for situations such as this
which is a plastic tube containing a metal strip which one can thread onto the
wire, but, if the wire has any sort of a kink in it, they will get caught and
stuck as they are a very tight fit, even on a completely straight wire.
A short will often develop after a gale when stray bits of flying detritus
become entangled around the hot and cold wires, but I can't say that the
plastic hose pipe has had any detrimental affect on the operation of the fence.
Incidentally, I heard part of a news item the other night that spoke of the
invention by of course, an innovative Kiwi farmer, of an unshortable electric
fence, but, unfortunately, I did not catch the details.

Hi Hank, I have two different electric fence controllers. Which kind of
controller do you have? I will copy below 7 common sins of fence controller
installations listed off the web and a link to same page with very good
instructions for troubleshooting.
There are of course different kinds of fence controllers and installations.
Sounds that you tested the controller's terminals and it has output there
but along the fence there is no electrical charge that you can detect? Is
this true? Here is the web info, good success.
THE SEVEN SINS OF
FENCE CONTROLLER INSTALLATIONS
1.
An insufficient ground system for the fence controller. (Refer to Step 2 of
the installation instructions.)
2.
Stray voltage may occur when the fence controller ground system is located
within 50 ft. of a utility ground, buried water pipe, or buried telephone
wire.
(Refer to Step 2 of the installation instructions and Radio Interference
Section.)
3.
Inadequately insulated lead-out wire and jumper wires (wire must be
insulated to 20,000V minimum). (Refer to Step 1 of the installation
instructions.)
4.
The ground wire is not adequately insulated and is located 20 ft. or more
from fence controller. (Refer to Step 2 of the installation instructions.)
5.
Inferior connections and splices of the fence wire, ground wire, lead-out
wire, and jumper wires. (Refer to Step 3 of the installation instructions.)
6.
Substandard fence wire insulation: cracked insulators, poor quality
insulators, water hose, plastic tubing, or the use of wood posts without
insulators.
(Refer to Step 3 of the installation instructions.)
7.
The fence controller is underpowered for the condition of the fence being
energized (i.e., rain, snow, ice, vegetation, rusty wire, and length of
fence).
(Refer to How Electric Fencing
Works in this manual.)

I was wondering if anyone on this list has installed an electric fence?
I installed one following the directions given but I do not have any
voltage on the fence line.
