I have an LCD mounted on my headrest which has been wired into the cigarette lighter. Red to positive Black/Ground to negative.
TV specs are 12 volt 7.5 watts.
When the car is off it does not work.
When the car ignition is 'on' (sometimes called accessories) it will work.
When the car engine is running it does not work.
I am waiting for a friend to bring a voltmeter around but I was under the impression that a cigarette lighter gave a constant 12 volts.
Anyone have any ideas why this might be happening?
