"It's obsolete, we don't supply parts, and we don't have a schematic" is
shorthand for "We want you to buy a new one at the ridiculous new price
- and besides, if we send you a schematic, that might encourage you to
open up your broken one and expose yourself to dangerous voltages (and
in so doing, us to litigation) that you might not be qualified to work
with, so we're not going to take any chances. Just shut up and buy our
overpriced one that'll die if lightning strikes anywhere within a 50
mile radius."

FWIW, where I am, we've got "Gallagher" units - hotter than hell, and
seem to be pretty near indestructible. According to the labeling,
they're made by an outfit in New Zealand. An interesting feature they
have is three terminals, rather than the usual two - Almost all units
I've encountered in the past have "ground" and "fence" - These guys have
the standards, plus a third labeled "half fence", which, according to
the tester, is just that - half the output that the "fence" terminal
shows.

Lotsa luck... I'm afraid you're going to need it.

You could try building your own from scratch.

Not all that pricey.
And their support is 2nd to none.

Have you checked Sams Photfacts?

I won't download the index, but you could, and take a look. A fencer
schematic would be pretty low volume, but stranger things have happened.

Encountered an *OLD* (old enough that it used an electromechanical
"interrupter" module) Bulldozer once... Never want to again! Was
swinging a machete under the fenceline taking out a stand of stinging
nettle that was threatening to swallow the whole fence. All was going
uneventfully - until, near as I can figure, on one particularly
energetic backswing, I got above the lowest strand of hot-string, and
when I came in for the next swing, sliced through it. The string went
"sproing", as strings under tension are wont to do, and the backlash
layed it against the right side of my (quite sweaty) head from temple to
ear. According to a bystander, I ducked, and an instant later, as I was
trying to swat the attacking whatever-it-was away, the charger must have
pulsed. She told me later that she saw me swat at the side of my head,
then I went down like somebody had snuck up behind me and hit me in the
head with a baseball bat. From my perspective, the whole world seemed to
"light up" - A blue-white flash covered my entire field of vision - and
I "heard" a sound that engulfed the whole world - sounded like I'd just
rung the world's biggest gong with my head. Next thing I knew, I was
picking myself up out of the dirt and wondering what the hell had
happened. Thankfully, I fell clear of the nettles!
DIY electroshock therapy, anyone? (remind me not to do that again
anytime soon!)

Like you and Gallaghers, I've heard that name once or twice, but know
absolutely zip about 'em beyond the fact of their existence.

Yeah, easier to just "shotgun" when there's an SCR involved. Can you get
any numbers off it? If so, shouldn't be very hard to source a
replacement (whether or not it's identical)

When I was a kid we had a fencer that used a mercury vapor flash tube.
A tanking circuit charged a capacitor until the voltage was high enough
to discharge the tube, which was hooked to the fence. The contents of
the capacitor charged the fence, until the flash tube voltage dropped (a
fraction of a second). It ran for years with no maintenance.
There was a little window, and you could see the tube discharge. There
was no fence fault indicator, the fence just kept pulsing, so you had to
test the fence with a blade of grass every once in a while to make sure
it was hot.

I bet we could find this stuff somewhere, right next to the barbed wire

Was seeking a schematic for a Parmak S.E.3. when I ran across this
I have one for a Blitzer 8568-B, maybe close? has parts list, location
of components and schematic diagram
It also covers Bulldozer 4465-B, Holdem 58-B, Thunderbolt 7765 and
International Harvester 1131920-R1. I've scanned it to PDF format,
looks pretty clear. I can send via email, let me know if you want me
to send?
By the way, as of MAY 2010 Zareba was bought out by Woodstream...

OOPS, Made a typo, it's a Blitzer 8565-B Schematic
