Okay, With engine off and reefer off, you read 12v on both batteries (I am rounding numbers). 

So confirm: with engine on, reefer off, you read 13v on both batteries?

With engine on and reefer on, you still read 13v on both batteries?

And with engine off and reefer on, you get, um, 12 on engine battery and, like, 11 on house battery?
