main  V


A= negatve pole of the ignition coil
B= B
C= central exit of the ingition coil
p= primari tesla coil , around 10 loops
s= secondary , around 500 loops
main = ground


- Are the connection to the main ground ok?

- should i connect toghether the negative of the ingition coil with the
ground of the secondary tesla coil?

- the ignition coil hase a positive pole and one negative, where I connect
the 12v DC, then there is the exit, and the spark happen between this exit
and the negative DC pole.

thanks
