Well ok, I'm not exactly drowning, but some help would be appreciated! Typing this in the bar at a campsite in Picardy on first foreign excursion with new van. The 'reverse polarity' light came on the mains unit when I hooked up. I know something about this, and had figured it wouldn't affect me as it simply meant that electrical kit would still be 'live' when switched off. As I don't tend to open them up, that seemed ok. BUT... neither the Eberspacher diesel heater not the fridge are working on the French juice. The heating and HW I can work around as the battery is being charged and I can run it off diesel. But the fridge - we switched it to gas and we're supposed to be here for three days. As we're paying for the lecky I'd sooner use it! Is there a quick fix that doesn't involve rewiring anything?
