RE: ignition coil for high voltage source

Hi Bill, All!

  I don't believe you need a resistor for this circuit.  I've run it for 7
minutes straight and the thing barely got warm.  How hot on the inside, I
don't know.  I wouldn't think it's too harsh on them, though.  Does anybody
know what the output voltage of that is?  Do plans for a good HV (4-50kv)
meter exist?

Hi Grayson and Coilers,

I really like the simplicity of this design.  I know the dimmer
switch is going to give the spikes of voltage necessary to get
the ignition coil to operate, however I was wondering do we need
a resistor of some sort to get the 120VAC spikes down more
in the range of 18Volts or less to prevent from destroying the
ignition coil?
