661TL

I have an LT166 which is not putting out any charge to the battery when it runs. I'd like to check the charging circuit's components, but I am seeing conflicting information on what it uses and where they are located.
According to the PDF Service Manual I bought online, the LT166 does not use a voltage regulator like the LT 133 or 155. It shows a single diode in a single wire from the alternator stator ring leading to the battery. I cannot see this diode, nor do I see the kind of connector they show, which has 2 wires, because it says a second lead from the stator feeds AC directly to the headlights.
What is more confusing is that I initally found many online listings for a voltage regulator with 3 wires specifically meant for the LT166???
Can someone help me sort this out and find the components I need to test? I see a single yellow wire coming from under the flywheel. The Service manual shows it to be a red wire, with the single diode in it??
