You could make a small coil and connect it to a galvanometer:

http://www.hometrainingtools.com/gal.../p/EL-GALVAN1/

and pass one of the HV fence wires through it. If the resistance it
too low you might get an idea of current flow. Good for a relative
measurement (just not quantative).

If it is a DC pulse, like the device my father had many years ago,
than a multi-meter with a series resister will measure voltage with
the caveat that as you are measuring between the fence and ground your
ground connection will have a large effect on the voltage that the
meter reads.

Just see how long a spark you can draw from it. The old "weed chopper"

I'd add a neon lamp and a high-value series resistor, maybe
a string of a couple dozen 100 K resistors. You need a bunch
in series so they don't arc over. As long as the lamp is
blinking, it is still working.

Karl,

Most fence chargers are prtetty simple, I have schematics of a few
designs. What brand is yours?

Units with a meter typically connect the meter to a 1 or 2 turn
secondary on the output transformer. Depending on the design of your
charger, the meter curcuit can be as simple as a diode and a meter
movement or somewhat more complex.

It would be well worth your while to open the charger up and take a look
at what you have. It could be a bad meter movement, a bad diode or even
a dead insect in the meter movement blocking motion. Supposedly, the
movement is sealed os a bug can't get in, but as you probably know they
can get into surprising places.

Its a Parmak precision brand. Made in USA - KC MO

A proper repair would be huge. I did find this on the web
http://www.dickselectricfencerrepair.com/ But likely, the repair will
be about the same as a new one. Mine is a 6 Joule 7K volt rated unit.
Now, I see you can get 10 Joule 12K volt units. Maybe its time to
upgrade.



For years, I've moved a metal post close to the wire to make sure it
pops a good arc. I'm thinking, make this accurate for a measurment.
I'll just set up a stop with a threaded bolt, probably use 3/4x10 so
each turn is 0.100". I know the fencer pops 1/4 to 3/8 when in top
form, if it won't pop more than about 1/8 its time to find the
problem.

Make sure the insulators are clean. They will bleed off a lot of the
energy if they are dirty. It goes without saying, but turn it off
before you do the inspection. ;-)


See if you can find an old Pomona or B&K TV HV probe with a built in
meter. You'll need to add a couple diodes to rectify the AC, but then
it's a simple matter of clipping the lead to ground, and touching the
probe to the wire.


Here is an example of a B&K on Ebay:
http://www.ebay.com/itm/4d0d4bb550


Fluke, Heathkit & others made probes to use with a 10 Megohm input
impedance meter, but they cost as much, or more than the probe type..

Tektronix made a really nice one -- good up to 40 KV. But
beware. It takes a squirt of a HV dielectric fluid (which is really one
of the now-banned refrigerants), so you are unlikely to get the full
voltage range out of it. (And no, I don't remember if I ever knew what
refrigerant they used -- just one of the FREON family. :-)

If you have some, a squirt will usually last a year or two
before it all leaks out.

And it has four or five trimmer adjustments for proper
waveshape at various frequencies. A *big* box on the BNC (with a collet
lock-on to keep it from jiggling off. :-)

Enjoy,

Yeah, a 6 Joule unit will get your attention if it hits you!

I have a partial schematic for a smaller Parmak. Parmak uses a somewhat
more complicated metering circuit than some. One turn of wire around the
outside of the output transformer connects to a circuit consisting of a
rectifier, followed by an opamp integrator and meter driver.

If you are comfortable working on the circuit I'll be glad to send a
copy of the metering circuit. Although it's from a different model it's
likely to be quite similar except for a few component values. It would
be quick and easy to check the diodes, meter movement and most of the
caps and resistors without disconnecting anything.

Your test unit should work, but of course you have to go up and connect
it each time you check the fence. In my experience, the cheap test units
with multiple neon lights indicating voltage are good to check the
output, but won't last if left connected permanetly.

Be glad you have deer and not elk to keep out. The elk around here will
go through a 6 wire high tensile fence as if it wasn't there, hot or
not. They seem to prefer to bust through even if the fence is low enough
to jump.

Go to your local farm store and buy a fence tester. You need one anyway
to find breaks in the fence. They are a series of high value resistors
with neon bulbs across the resistors.

Use the tester when you need to, or just hook it permanently to the charger.

They make Electric Fence Testers nowadays. For instance:

"Get accurate and reliable voltage readings of your fence line or fence
charger with simple, one-touch operation. Use the Zareba® Digital
Electric Fence Tester to measure fence line and fence charger voltage.
-Combines digital accuracy with ease and convenience
-Rugged easy-to-carry pocket-size case made of heavy duty ABS plastic
-Digital accuracy from 500 to 9,900 volts
-Large easy-to-ready LCD display
-volt battery operation (battery included)
-Automatic on/off that prolongs battery life..."

If there is grass or somesuch on the line, a spark will develop at the
charger if you disconnect the wire and hold it far enough away from the
terminal to form a 1/16 in or so wide gap.

Even with no grass that will happen due to line capacitance or line

Plugged in the electric fencer and the meter reads "short" but it
still shocks the **** out of you. Don't ask me how I know this.

Not having a volt indication will be a real problem, no way to know if
grass etc. is knocking down the effectiveness. A fencer puts out a
high volt burst a small percent of the time. On the order of 7K volts
for 50 miliseconds once per second. Is there an easy way to add a volt
meter? Just a relative indication is all that's needed. or time to buy
another unit? ($250)


If there is grass or somesuch on the line, a spark will develop at the
charger if you disconnect the wire and hold it far enough away from the
terminal to form a 1/16 in or so wide gap.

Even with no grass that will happen due to line capacitance or line
impedence.

Not in my experience but I'll check it in the morning.

It sure does with 2 miles of fence. Or at least it always did when I
was back on the farm. With the Bowman Weed Chopper.

Too many shorts on mine right now to really do a test, nothing inside the fence since last fall...there's probably only ~400 feet of wire total.

--but I suspect any sparking would be rather small lacking a short unless the fence is exceptionally long, in which case there should be only single spark unless any resultant capacitive charge has leaked back to ground potential for some reason prior to the next pulse cycles' having occurred.

Mine has a simple Neon bulb across ground and the hot side.

Works great, less filling

Really?

"Hurt" aint the word.

For Liberals, the truth is like salt to a slug.
Sunlight to a vampire.
Raid® to a cockroach.
Sheriff Brody to a shark
Bush to a Liberal

The truth doesn't just hurt. It's painful, like a red hot poker shoved
up their ass. Like sliding down a hundred foot razor blade using their
dick as a brake.

They HATE the truth."
