OK. I've had my RV for 70+k miles now, and I still don't understand the terminology. First off, assume dry camping, engine and generator off, no shore power. Above the sliding door, there is a panel which allows me to turn on the house batteries so that I have 12 volt for the lights.

When the rocker switch (on the far right off the pane) labeled battery is depressed to the "on" position, I always assumed the circuit was completed and thus, I had power. And I do. If depressed to the "off" position, I don't have power. Is this the battery disconnect switch? Have they reversed the labels - the "on" label means the battery disconnect switch is really off, allowing the circuit to be complete? If so, do I need to flip my switch (what I see on the panel) to the "off" when I plug in to shore power?
I don't think I've ever done that in all this time.
The only battery problem I had was when the alternator Y cable went bad and the chassis and house batteries weren't charging while driving.........I turn the battery panel switch to the "on" position the minute I get in, before I start driving, leave it on while camping (battery, generator or shore), and only turn it off when I'm finally home (where I don't plug in).
Any and all input welcome.
