Hello there,
not exactly an "overland vehicle", but still my main means of travelling is a Citroen BX. As we sleep in the car and use it just like a caravan, I'd like to equip it with a second battery in such a way that the engine will always start the next morning, even if we've used auxiliary devices (like the radio or a fridge) all through the night.
During my stay in australia I owned a Landcruised with this kind of setup but that was three years ago and I don't know how it worked.
What kind of devices and cabling to I need for this? I found a few instruction manuals that are made for people that already have a dual-battery setup and just need the separator. But I'm a bit confused regarding that, because these plans usually involve a separation of electric circuits, apparently. For example these two:
That separation between "main loads" and "auxiliary loads" I don't understand. Isn't it possible to have a setup with a single electric circuit, but just one battery powering it unless you're turning the key to the diesel-preglow and starting positions, where the second battery will kick in?
Thanks for any help provided!
greetings from Switzerland
