Re: [TCML] Ignition coil etc

[Henry Hallam <henry@xxxxxxxxxxxxxxxx>]

I don't think that will work too well.  You might even damage the
ignition coil, and you won't realise its full HV potential.  Ignition
coils should be driven with something closer to a square wave rather
than the sinusoidal output you'll get from your transformer.  The
sharp falling edge on the driver waveform is needed to get the proper
inductive 'kick'.

Try a dimmer switch circuit: http://wiki.4hv.org/index.php/Ignition_Coil

Is there anything I should put between the coil and the transformer to protect either or both when I wire it up and plug it all into the wall? Is there liable to be a backlash from the coil when I unplug the transformer? Should I put a switch in between transformer and coil?
