I don't think it was your question that triggered the drawing. More like one that broke the camel's back in Feb two years ago. There surely are a lot of misunderstandings regarding this electrical power plant. I tried to cover the whole 19 years, or at least those without Sev/Motorola/Marchal and external reg's.

What I could not tell from your post is where/how you were checking for D+ voltage. Backprobing connected or disconnected, key on, motor running, etc. But then I couldn't tell what model car you were working on either until I spotted your dupe.
