Re: Ignition coil burned?

I think that that may be your problem... ignition coils are:
1) meant to work at a peak of 16V
2) work at about 10A RMS
You probably exceeded both. The voltage doesn't cause heating (p=I^2R) but
it might have caused insulation breakdown.
Grounding the dimmer shouldnt make any problems...im not so sure about that

If I have made any physics/electrical booboos please let me know... im a
chemistry man really :)

Be safe,
