    Wiring for Cigarette Adapter

    Hi all,

    Does anyone have any info on wiring a cigarette adapter. The one i have has a spring connector on each side. Both connectors touch the negative outer terminal of the cigarette socket, but one is connected to the the centre positive terminal. I have connected a red wire to the this connector, and a black wire to the other. I am not getting a voltage across the two wires.

    Any ideas ?

    Stupid question but is your key turned in the ignition? It doesn't get power unless the key is at least at ACC

    Not true. My cigarette socket is live at all times, even with no key in the ignition.

    Does anyone have a wiring diagram for a cigarette socket plug ?

    they are pretty simple to use and cheap if u dont have one allready

    I am using a multimeter - that's how I know that I'm not getting a voltage.

    The meter indicates +12v when the engine is off and +14v when the engine is running. I just don't get a voltage across the red and black wires of the cigarette adapter when it is inserted.

    Again, does anyone have a wiring diagram for one of these plugs so I can at least check my wiring ? I know the plug is not faulty as it has an LED that lights when it is inserted.

    Normally the tip of the adapter is 12v and the metal body/springs are ground.
    If this is what your meter is tellingyou then you've wired the plug incorrectly or have a short.
    End of story.

    Does your cig lighter plug adapter have a fuse inside the center contact?

    If so, it is probably blown.

    If not, is it supposed to?
