Hello everyone, We have a new Jayco Journey and my query is this. When connected to an on site powered site are the lights running off 240 mains or the 12 volt battery ? I would have thought the lights would be drawing from the 240 volt power supply together with the fridge,Air Con and all the other 240 volt appliancesWhen the 12 volt switch is turned off, the lights turn off.Does this switch have to be in the ON position when connected to 240 volt power?? Thanks johno

Hi Johno, I believe your lights will run off your 12v batteries. Your 240v should control your Air Con ,Fridge ,Water heater , ect. Your water pump will also be 12v only. The 240v should charge your battery when it is connected at a camp grounds, Hope this helps

johno, they use 12v so they don't have to put 240v bulbs in as well as the 12v ones. When you freecamp you run only 12v so 12v light bulbs ( hope they are led to save power ) so when you connect to 240v your van should have a 240v -12v battery charger to top up your batteries.

Hi Johno
Yes if you want lights it needs to be.
Your lights can only be 12 volt. There are no lights that I know of that will run off 240 and or 12 volt Three way fridges will run on 240, gas or 12 volt and not very well on 12 volt. Compressor fridges usually are 12 volt and some 12 & 240 Air cons 240 only, Television either is a 12 volt or 240volt will not operate off both. When 240 is connected to your van the battery gets charges to run the 12 volt lights & 12 volt appliances.
If you purchased your van from new I would like to think that your Jayco dealer would have gone through all the operations.

With the advent of cheap and efficient LED lighting, there is less and less reason to have 240V electrics in a caravan at all.

In the past 12 volt lighting was pretty piss poor, to get any sort of viable light output 240V was needed.

All the LED lighting technologies to date are DC native and running them off 240v just makes them less efficient.......in this day and age a caravan manufacturer would have rocks in their head to install 240V lights.
