    Post splitting cigarette lighter for inverter


    I'm going to splice into the cables for the cigarette lighter to power the inverter.

    Anyone know if I can leave the cigarette lighter socket still connected, or should I disconnect it? It'd be nice to have the socket still available, but I don't know if that'd electrically 'work'.

    That's what I did.

    I have a plug in the trunk for the inverter (that I installed) and left the one in the dash still hooked up.

    They are both spliced from the same wire.

    Yes you can do that but...

    1.) if your the lighter is not attached to the accessory power in your car remember to install an on off switch (or you will drain your battery)

    2.) remember to put an inline power fuse on the wire that u spliced going to the inverter.

    Is the inline fuse really necessary if the inverter has its own built in fuse?

    YES an inline fuse is necessary...

    Ok just a bit of advice for all. If you add any devices to your car and it is not a direct replacement for a piece of factory equipment then yes you should/must add an inline fuse even if the device has a fuse attached to it... I am late for work i will talk more about this later if necessary

    The fuse for the cigarette lighter is not good enough for a real electronic system. You could easily burn out your cigarette lighter and other assorted things w/o a different fuse. A friend of mine did that to his mom's Chevy (then he got his Celica, so he kinda whistled and walked away ;-)

    What size fuse should I use? The same as the one for the circuit in the fuse box?
