Has anyone ever had problems with their house wiring when running a
coil?  When I plugged in my coil to do some testing, I noticed a flash in
the corner of my eye.  I quickly unpluged the coil.  I then tried it
again, to find that one of the electrical outlets in my basement was
sparking when I plugged in the coil.  Our house isn't old, so I can't
blame the problem on old house wiring.  It really scared me as I don't
know if the other outlets in the house could have sparked.  Since then,
I haven't fired.  The coil supply is only to 30 ma 15,000 V neons.  One
of them has since died.
 
 MG> You didn't state if you were using a good line filter on the input

 MG> make sure your coil ground is seperate from your house wiring ground,

 MG> Make sure your coil secondary is grounded to this ground as well, I've
