Re: Requiem for a Piglet: I am a murderer

Hi Dave,

Slow down here....

1.4 ohms measured with just a hand held meter may be perfectly normal!!
That little 9V battery is not going to magnetize that big iron core in the
there worth a darn.  The primary "resistance" is mostly "reactive
inductance" that your little meter can't see.  200 feet of like 10 gauge
wire is not going to have much DC resistance!

So don't go draining oil and lifting cores just yet!!

Here is what I would do.  Disconnect the output terminals of Ariel from
"everything", just two unconnected horns.  Then get a BIG high wattage
light bulb, space heater or hair dryer and run it in "series" with each of
the two legs off the center tap.  If it is shorted, the appliances will run
fine.  If not, you will only be able to get about 0.25 amps though each of
the 120VAC legs of the primary windings.  Basically, you need to run about
10 amps of 60Hz AC through the thing to get a "good" reading where the
cores get good magnetization currents.  The fact that the legs all read the
same now is a giveaway that it is not shorted.

Is the secondary shorted?  If so, the above test will fail on both legs.
1K on a pig's secondary seems pretty normal for pure DC wire loss.  Again,
the "AC" reactance is the key.  A "little" streamer back flash is nothing
compared to the lightning strikes these babies are meant to survive.  If
you got this pig from anyplace with a reputation, they probably pulse
tested it to levels that make a Tesla coil look trivial.  Pigs just don't
die...  Gomez killed his after running it a few years "without oil" at like
10kVA...  Streamer strikes just don't have enough energy to do much
damage...  Murder?  I ain't even sure there is a body yet...  Start testing
"everything"...

Of course, something probably "is" broken...  Try running a big high
wattage heater, or what ever, off Jennifer and check the wiper and her
contact windings for a "bad spot".  If found, sand and grind the heck out
of it and go on...  You really need to test each part out well and be
"sure" that you have a dead part before getting too excited.

My guess is...  "Condenser Products 0.05 ufd caps"...  If you got blown caps...

Cheers,

	Terry
