The off position wont affect the fridge cos that will be wired direct via a relay and will be live when the car engine is running only. I would think the same would apply to the battery charging though couldn't be certain, come on where are all the Geist owners??. Reckon you'd do yourself a favour by buying a basic multimeter, only about £7 or so. You apply the leads to the battery with it set on DC and it will read approx 12.7v, then with the switch in the open circuit position plug into the car and keep it running on a fast tickover. If the reading goes up to about 13.8v then the charging circuit is not running via the switch. If nothing changes, switch to on and the meter should then rise to 13.8 proving the charging circuit is controlled by the interior switch.
With a bit of luck you wont have to bother if someone with a Geist surfaces in a mo.......Mick

OK, so I surfaced. So far as I understand the circuitry in my Geist, when I connect to the car, the fridge and charger operate,whilst the engine is running, but all else is disconnected via a relay, called the habitation relay. The switch to which you refer disconnects/connects 12v circuits in the van when it is free from the car. If you are hooked up to an EHU and turn the switch off, it does not affect the charger or the fridge, just the lights and pump circuit. At least, that's what we sussed out through trial and error (lots of error initially!)
