Hello all. My wife and I are new to caravanning and have just bought a cheap starter van, a swift Corniche 14/2, around 1989 we think. It does not have a leisure battery fitted yet and and I have read some post on forums that indicate that the vans charger can provide a 12v supply with no battery fitted. Is this the case? Thanks
i dont think so, but contact wizard in repair section, he will give you more info
------------- its easy enough to be pleasant when the world rolls along like a song.but a man is worth while if he can smile when every thing goes f------ wrong.
I have just sold a 1990 SWift challenger and it had a Zig Charger and this did power the 12V lights etc. But the hot water heater needed the battery connected to ignite the burner.

Can you just plug it in and see if you get any 12V
DON'T DO IT...
... the charging current provided by chargers, plus the output voltage is only suitable for connection to a battery and mustn't be used as a power supply .
It depends on weather you have a charger/transformer or just a charger , if it's a charger/transformer then you'll be able to run your 12volt system when on hookup with no battery , you may notice the lights slightly flicker when running the water pump . Where as if you had a battery in the system it would smooth the 12volt supply and any flicker would hardly be noticeable . From info i have on a 1991 Corniche there's a good chance you have a charger/transformer .

I didn't suggest they did! I was talking about plugging in the EHU, and seeing if there was 12v at the caravan plugs. Which I thought the OP wanted to know.
I use my battery charger as an external 12v supply for my cooler box, have done it many times with no problems.
Do a search on this. We asked the same question before buying our 1st van and was easily convinced to buy 1. On our 1st weekend away there was a powercut which lasted all evening and night- we were really pleased to have the battery backup!!

That was my point. If the caravan has 12v sockets and lights, then the 12v must come from either a battery or a transformer.
So if you plug in the 240v EHU and the 12v thingies come on, then you've got a transformer, and a battery isn't necessary (if you only go to EHU sites)
If they don't come on, then you haven't got a transformer, and you need a battery to make these work. If you've only got a battery charger, it won't be connected to anything else other than the battery, so the argument it isn't safe isn't relevant!
If you haven't got 12v sockets and lights, you wouldn't need a battery, would you
