OK, I have to let you guys in on a couple of things.
1) I firmly believe it is not "Who is right; but what is right."
I don't need to BE right; I need to know what IS right.
2) Herk7769 and Lou are the same guy. (If you click on my name to the left of my posts you can see my profile. If everyone updated their profiles you could preface posts directed at a person with their real first name if you so choose.
3) We tend to defend our most closely held beliefs long after we should have ditched them. Based on my experience with that stupid socket light I have held the understanding that the 12VDC line was cold with the key off. All further posts stemmed from the falsely held belief.
4) Every thunder cloud is beautiful; from a distance. they suck up close.
(The old "silver lining" thing)
5) I learned a lot researching this thread. Far more than I would have without digging into the books to prove I was wrong. I found circuit diagrams for my truck both in the truck maintenance manuals I bought when it was new and the Net. Some are pretty cool and will be appearing from time to time.
To RPAspey: Yep, I had this picture in my mind of a rack on top of your truck with the panels on it. I thought your unique solution was pretty cool actually. To bad they are on the camper like everyone else.
To Ron: Since he wants to protect the truck from power coming FROM the camper's solar controller, the easiest way to do that in a GMC/Chevy is a reverse biased diode between Post 1 and the Camper's 12VDC Vcc line. Since that Vcc line is fused at 40 amps,it would have to have a pretty big honking blocking diode I am thinking. No?
