   Measure resistance between screw terminals and

   look for 4-8 ohms. Measure between any screw termnial

   and the tower (spark) terminal and you should see

   perhaps 1000 ohms or more.



   This only shows continuity and won't reveal shorted

   turns . . . but since these things are generally

   oil filled, shorted turns are unlikely.
