<< Coiler Types,
I've been tinkering with my new pig, trying to ascertain if it's
serviceable or not. I'm too chicken to apply mains power to it--I
don't have anything to ballast it with. I ohmed the 11KV winding,
and the needle (honest, a moving needle) slowly settled down on
about 350 ohms. The 240V winding was practically a dead short. I
have no idea what the resistance of pig windings should be. Do my
readings sound right?
I was desperate to test it somehow, so I tried my 6 amp car battery
charger on it. I made a spark gap of about .25" with some stiff
wire. I clipped one charger lead to one 240V terminal. I tapped
the other charger clip against the other 240V terminal, and
was rewarded with a sharp "SNAP" across the spark gap. I think it
works! Not bad, considering the price tag (it was FREE).

Greg,
You can test it by using a variac to control the primary 240 v input, use
resistive ballast like several oven elements in parallel (electric heaters,
etc.) in series with the pig primary - or of course a welder or other
inductive ballast if you have it. Now make a jacobs ladder from the HV
bushings using heavy copper tubing.
Good score!
