Bev, When you say it starts easily on the house system, how exactly are you doing that? By combining at your battery switch? If that’s the case, there’s a connection issue between your engine battery and the switch — an issue that disappears when you combine.
As Fred mentioned, low 12’s is very low for a battery bank and you should be thinking about replacing that. Should be more like 12.8 (or higher if you have a solar panel like I do). Fred Street knows his stuff. He has the "Street Smarts”. That sounds like a second issue though — connections will probably explain that 5V drop. Happy hunting. All the best, Edd Edd M.
