Posts overlapped, is that not a weakness in that a malicious person could discharge the car battery or is there a voltage sensng relay?

How do you do that with a standard 12N socket?

 

I would assume they are available to purchase with the older 7 pin sockets, or perhaps use a 7pin to a pin adapter?

But there is not a permanent live connection in a standard 12N socket, even using the auxiliary caravan socket I 'm not sure that you can backcharge through the voltage sensing relay, its been years since I did one so cant recall the pinouts but AFAIK you cannot charge the cars battery through a 12N socket.

J.R. is correct the 12N socket has no permanent live but the 12S should have one on pin 4 and an earth on pin 3. There is also an earth on pin 7 which is a high current one for the fridge when towing.

You can't, I'm afraid, only with a 12S or the modern and better 13 pin ones.
12n only has connections to lighting circuits.

 I don't have the cigarette socket attachment for my Ctek so I can't attach that way.

 

 

 

That aren't that expensive to buy
