Dodge sportsman vogue 77 electrical questions

All that means is he bought a 1977 class c (dodge sportsman)

The battery in back can be inferred as being the ' house battery'

Because the engine battery is normally under the hood for that year

Read the title of the post. Dodge Sportsman Vogue 77, I understood it immediately.
But, I like vintage RV's.

Moved from Forum Technical Support

THIS sub-forum is for problems with the forum software.
I think the owners should seriously consider changing the name.....as a LOT of technical RV questions show up here by mistake.

You would get MUCH better answers if you specify exactly what kind of RV you have.

If you bought it new, ask the dealer.
If used, ask the previous owners for the manuals that came with it.

Welcome to the forum.

The secondary battery is your House battery. It will operate the inside lights independent of the starter battery.
You should have a switch inside the coach to turn the battery(s) on/off.

Make sure your house battery is charged and terminals are clean before starting to diagnosis your electrical problems.
