Electronic ignition upgrade / voltage regulator question

i would goto the dual fld set up. just seems to be a lot more stable to me. i know guys that have used the blue constant out put regulator but i never trusted those things.


here is the conversion diagram. you add the wire i have colored blue..

This is a good diagram of the charge system, and I don't want to hi jack this thread, but can you tell me where the ignition 2 wire goes off the ballast resister. This might benifit challyrtse also. And does it matter if the field wires are hooked up opposite? Thanks.
