No worries. You went to a supposedly reputable source, and as too often is the case, somebody with probably only partial knowledge at best posts incorrect info that to the majority of readers who think of electricity as some form of 'magik' buy into. As a working electrician for almost 40 years, some of the scariest **** I ever saw was done by somebody who had just enough knowledge to be dangerous.

The biggest misconception a**** DIYs that work on their own cars is that a vehicle electrical system runs on 'DC' power and principles. The Ohms law equations are the common knowledge base for that and is relatively simple to understand. But the reality is very little of the electrical bits on these systems can be completely described using it. Yes, you're using a DC source, a battery. But other than purely resistive loads like lighting, lighters and some gauges, pretty much everything else operates using AC principles in one degree or more. The small stuff can generally be ignored, things like relays, solenoids and small motor loads for example. But large motor loads, charging systems of any kind, and ignition systems are where ignoring their AC characteristics can cause issues.

Automotive generator charging systems had become standardized by the late '40s. While there were design detail differences, operation was all the same.

 

I get most of this stuff. I have my A&P license for 55 years. Worked in Gemeral Aviation (small stuff) for about 20 of those years. Even had my own shop for 6 years. My wife and I worked together. We look back on those times fondly. I've been working on aircraft and cars since I was 13. Built several cars from the ground up. This Vette was a beat up old texas racecar with a straight axle. Converted to pro street. I do everything myself because I love to. Why should I pay someone to learn when I can.
