Continuity of two power wires out of the stator in the wiring harness

[Bigpig41]

Studied the li'l wiring diagram for these bikes found in our Owner's manuals. On this site there's somewhere that video on converting our bike from 1/2 wave charging to full wave charging where the author tracks down a "tap" off the yellow wire coming from the stator on its way up to the regulator/rectifier near the steering post. He states that branch off the yellow stator wire is how AC power gets to our headlights. I'm not finding that tap of yellow wire AC power going to the two headlights on the wiring schematics.

Guess I need to get out there and see if removing those two headlight bulbs from their sockets eliminates this yellow wiring grounding out.
