That is one of the better descriptions of RV 12v systems I have read. (Have read many as well as being an aeronautical engineer for many years where a solid knowledge of electrical and electronic systems was part of the education and application package).
It is in simple lay terms and easy to understand. Everyone who lacks savvy in this area shoud read it and other such technical literature.
Sooo many people do not take care of the batteries or appreciate the danger when working with them.
Knowing what everything in your coach does and how it works is essential for me and this type of support for the forum is commendable. Good show.
