How could I check to make sure my Mag wirings are correct?
=20
This is what I did. I pulled out the top lug from all the jugs. I
turned the ignition switch to "BOTH" position. I laid all the plugs on
the jugs making sure that the threaded part was in contact with the
metal part of the jugs. I turned the prop by hand in the rotation
(clockwise standing behind the plane). As I pass through TDC, I can
hear two impulse coupling clinking in the Mags but I did not see any
sparks fly in the plugs. I was expecting a healthy dose of "Zap" as the
impulse coupling fires.

I went around with continuity checker and made sure there was good
connection between the mag switch, mag, the engine casing, ground line
and they all seems good.
=20
Any tips?
