Live Cigarette Lighter connections.

Recommended Posts

My S Type appears to have two Cigarette Lighter Connections:

1/ In the ash tray (never used thankfully) this will work if the ignition is turned on but is not live with the ignition off.

2/ In the storage box between the two front seats this one does not appear to work at all when anything is plugged into it, neither with ignition on or ignition off.

Why does No 2 not work at all and can I somehow have either of them working with the the ignition turned fully off and the car locked.

I ask this mainly because I want to use an OTEK 5.0, which Otek`s website states can be powered from a cigarette lighter connection as long as the connection stays live when the ignition is turned off. This would resolve the problem I am having with not wanting a mains connection into the boot, from the house, whilst the car is locked overnight on the drive because of not having a garage.

Have been dissuaded by this Forum not to use the Solar Panel chargers which will connect via EOBD connector which works with ignition off and car locked.

Many thanks for your time and any possible answers or advice.

Best Wishes and Regards, John

Hi 

I believe the one in dash is lighter

one in console between seats is Aux 12v socket.- might be a fuse that's why its not working.

Many thanks.

The one in the dash is definitely a lighter, as it has the lighter in it. It only appears to work with ignition on. I am wondering if there is actually anyway it can be made to work without the ignition turned on.

Is the 12v in the console likely to work with out ignition on and can it, if it does, be used to power a OTEK 5.0 charger/conditioner. I will have to attempt to fine out where the fuse for this 12v console connection is located.

 

Many thanks and Regards, John

Have now found a fuse box layout diagram and it appears the console 12v is on the same fuse as the handbrake on illumination light and is 10 amp fuse.

My Handbrake illumination light (Red on the dashboard clocks) is working. I am therefore (rightly or wrongly) assuming that the fuse is in good condition. This does again pose the question why does this connection in the console not work. I have plugged a tyre inflator in there and it does not work, where as it does work in the cigarette light but only with ignition on.🤔😕

Hi John

found F32? as well check out video.

As far as I know - I am not an expert-

To use the cigarette lighter in any car even older cars you have had to turn the key to the accessory position for it to be able to work. They have never had constant power to them even when turned off because doing so causes unnecessary drain on the battery when accessories are not being used

Would only be on if hardwired to battery

If not fuse / relay  assume it would be wiring fault? or unit  itself?

Best Regards,

Julie.

Many thanks. I will check that actual fuse tomorrow as it appears to be only feeding the console connection.
