Not to insert myself into this fun little back-and-forth too deeply - but this thread is fundamentally NOT about internally regulated alternators. It's about the requirement for overvoltage protection with Earth-X batteries - by any suitable method.
It devolved into some deep alternator and regulator voodoo, but that's not the point of this thread.
I agree, I'm moving my posts back to the other thread: http://www.vansairforce.com/community/showthread.php?t=154377&highlight=charging
