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 the batteries while I am using them, they quickly get below 11.9 (to 11.6 or so), but later, when not in use, seem to be OK again at low to mid 12. They are BRAND new. Like one day old!
So, do they read lower when under draw? And I should only read them when they are not in use? Or is something wrong with my readout on the wall?
