It doesn't make any difference whether the primary and secondary are wrapped
the same direction (unless you're building multiple coils in the same
system, as in a bipolar system).  All it does is change the relative
polarity, but has no real effect on sparks, voltage, etc.

Do you really need to measure the frequency?  Or, do you just need to make
sure that the primary and secondary are tuned to the same thing?
