<< 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!
