You don't say type of Van you have but there is often a switch marked 'Car' & 'Van' which would need to be set to 'Car'

 

eg. Swift group Vans of recent years.

Thats absolutely how it should be and quite normal. The car takes preference over the vans 12v system when attached.

Hi Jt

will the 12v battery in the caravan be charging when the 13 pin is connected you would think the indicator would show charging same as 240 v when on ehu on site

Yes with the engine running. But maybe not exactly the same voltage depending on the cables from the car relay and via the vans wiring. You should certainly see a change on the voltmeter reading when starting the car engine.

I don't think you do see a reading on the volt meter when connected to the car while running, i recall when i had a charging problem, i had to take a reading across the battery terminals.

 

Probably due to the relays inside the caravan.

You should not see anything on the vans 12v system when the car is connected. Exception being the fridge line and the recharge circuit assuming the cars engine is above idle. Relays isolate the vans supply when car connected.

My meter shows no voltage when connected to the car . Only shows any voltage when the master battery switch is turned on .
