House battery voltage under draw?
I have a new (to me motor home) and an upgrade from my old one. In my old RV, I had to check the house battery voltage manually. With the new rv, I have a switch on the wall. However, when I check t...

To answer some questions...
1. When I say the batteries when NOT under load go back to low 12 again, that is BEFORE they charge back up. They do charge back up to full again.
2. They are also 6v batteries (2 of them obviously). I will check with a meter on the terminals and confirm the reading.
3. I am NOT connected to shore. I do have a solar panel and it does in fact charge the batteries (reading over 14v when charging). I have also driven and charged the batteries. They do charge and seem to hold their charge when not in use.
4. The "load" is minimal. Just a few lights. The volts drop almost immediately when a light is on, but does not seem to continue to drop. As if 12v minus the 1v in use should equal 11v. I was wondering if that is the case?
5. The meter (or at least the display) is far from the batteries. I have a 2000 35ft Winnebago, if that helps?
However, if the volts do appear lower when under load, how then do you know when to stop using them? I assumed you could check them in use and know when you need to stop.
