Permanent Live To Cigarette Lighter

I know it's not Towcar talk but just wondering if there is any help for an electrial question

 

My wife has a VW Beetle and the cigarette lighter is permanent live. I have bought a bluetooth for the mobile which plugs directly into the cigarette lighter (brill piece of kit by the way) found a website that has them reduced by 50% from £58 to £29 http://www. mobilefun. co. uk/nokia-hf-6w-p6604. htm . Really good quality.

 

Anyway, back to the question, as hers is a permanent live, whenever the car is turned off, she has to remember to switch off the bluetooth as it will remain connected to the phone (within range) and permanently on. I have bought one as well for the Sorento, and when the ignition is switched off, the bluetooth obviously switches off. When I get back into the car, it switches on and automatically connects to the phone.

 

I was planning on changing the permanent live to a switched one and was wondering if this is an easy job!

 

Cheers and thanks

yeah its easy.

take the permanent feed and wire it into a 12v relay then take a piece of wire (same size csa as the in)and come out of the relay to the cigarette lighter and control the relay by the 12 v ignition wire and a suitable earth (body work)

ignition on relay on cigarette lighter on

ignition off relay off cigarette lighter off.

if you pop into a car spares and ask for a 30a relay. it only has 4 terminals. 2 for the feed in /out and 2 for the relay coil. the relay terminals are numbered, if you need to know what no. goes where let me know and ill check mine.

Most automotive relays have 5 terminals as they provide for a "break" option when the relay is activated.

i know that, but if you only need 4 terminals why buy one with the extra

It may be worth checking the fusebox. If the c/lighter has it's own fuse pull it and check which terminal in the box is live. The other terminal will be to the c/lighter. If there are a spare fuse sockets in the box find out if one is ignition switched. If so, make a suitable fused link wire with blade terminals at each end to bridge the original c/lighter connection to the ignition connection.

I wanted the opposite on my car where the three accessory sockets (not c/lighter) are ignition switched. I removed the relay from the fuse box and linked the appropriate connections in the relay holder to provide a permanent supply. The relay holder is fused separately.

Odd how some manufacturers think lighter sockets need to be live all the time and others do not. The obvious solution would be for manufacturers to make either an easy option for the owner to select themselves.

 

An easy way to make the socket switch off, would be by using a split charge voltage sensing relay. Just insert the relay inline with the feed to the socket and when the engine is not running, it will cut the supply off.

Hi Mike,

 

you missed one little thing

Works in 12V/24V sockets to deliver 5V output

I guess that rules it out.

Ah, it finishes in a USB socket. Well spotted, of course I new that all the time, just checking if you were all awake, which clearly I was not. :D

 

Still a good bit of kit in the right circumstances.

 

Ok, back to bed. :ph34r:
