[TR] Coil and spark plugs polarity

[Tony Drews]

The center electrode will be the opposite of the ground that you're 
using.  Negative ground = positive center electrode, Positive ground 
= negative center electrode.  Has to be that way to produce a spark - 
otherwise there's no current flow.  I believe that the coil has a + 
and - connector but need to go look again to be sure.
