Please can anyone help with this. In our caravan there is no 12v socket built in anywhere and I would like to power a 15" LCD Television. I haven't a clue where to start with the wiring or even what bits and bobs to buy. Here is a picture of the power lead for the TV, the TV is 12v. How do I get it hooked up to the battery. I do understand that you can branch off from the existing 12v ring in the van, but wouldn't know where to start there either!?
Hi, from the looks of the pic, You have a 240v lead that plugs into a transformer that supplies your 12v power for the tv? do you have a sepearte 12v input lead? if so what plug\fitting does it have on the end? You could fit a cigar type socket and spur from an existing 12v feed or depending on where it is run a feed straight from the 12v fused supply source which would be better

Hi no i've only got the cables shown up there. I wonder if Maplin would sell a length of wire with the bit on the end which goes into the TV! Is it a simple job to site a 12v plug socket in a panel near to the battery compartment?
Jamie, you may be better getting an inverter (12v to 230v). Make sure it is a good quality, true sine wave converter tho, and rated higher than the TV wattage.

Is this right?.. You basically connect the inverter directly to the battery, it changes the volts from 12 to 230 so that I can plug the TV into it using the cable in the picture above, then the power gets converted back to 12v and powers the telly?
If that is right, would it eliminate the much talked about voltage drops and surges which can damage LCD televisions when run from 12v?
Agree with above, This would also allow you to run other 240v items if without ehu, though not all at once of course...Yes you could get a 12v cable and as long as the plugs are correct and you wire it correctly. Fitting a 12v socket just means drilling the hole to suit in a suitable place, Then wiring into existing power supplies or if near the battery you could connect directly using a inline fuse.

Thanks for the advice I had to go for a modified sine wave inverter in the end as my budget wouldn't stretch to the other type. It's a Nikkai one from Maplins on special offer £39.95 for 600W. Probably some overkill there as the TV is 30W!. Just hope it does the job now, I bought 2m of cable so it can be sited well away from the TV, dont know if that will help with interference problems? Not sure whether to connect it straight to the battery or come off where the existing battery wires meet inside the van.
