funny really as my first thoughts were the same as Angus's. That's men for you.Judy, I had a 2006 Ace Award from the Swift group. The switch had to be in the VAN position whilst towing for the battery charging and fridge supply to work. It should also be in this position when on site with EHU, and battery charging is required. When power is required from the car whilst on site the switch is in the CAR position. There was also a central position [unmarked] which allows the van 12v systems to operate without a battery whilst on EHU.
Be careful as the answer to your question will depend upon the control box fitted.

One more question ( might be daft )I can tell you Ray without any problem the control box is a NE2006 CWS.
So to clarify for towing, switch on van for fridge and on site for EHU also on van ?
I have read the book,and thought i understood it, but wanted to check as someone told me i was wrong, thanks Ray.
Judy, To answer your question regarding the CAR supply. If you never had a van battery, or it is flat, you can run the van 12v systems (lights, water pump etc) from the car battery. There is a "permanent feed" on the car 12S (grey) socket which can power the van when the switch is in the CAR position. This feed is also used to charge the van battery when on the move.Judy, it is ALWAYS in VAN position unless you want to run the van electrics from the car when it is in the CAR position. When on EHU and you remove the battery you can run the van from the Power Supply / charger with the switch in the unmarked Central position.
I am fairly sure my control box is the same as yours but I no longer have the van.
If you have any doubts or want to know how you can check the operation fairly easily then let me know. Ray
