	Hello, Here is an article which appeared in May 2002 Nuts and Volts Magazine. It tells about inducing a sharp pulse into a coil and then counting the ringing effect using discreet hardware. The 4015 counter could be replaced with a 8051 type IC. Regards, Charles Bannister http://members.aol.com/cpu8052/ringcounter.gif

         So the aim is to test for shorted turns?              01/01/70 00:00
