Hello,
What is the best way to rig up (easily and cheaply) a cigarette lighter socket (for lights, phone chargers etc) that doesn't go off when the ignition goes off.
Is there a common positive cable that is readily accesable? Whats the best earth inside the car?
Also, is there a one - way diode or such in the dash mounted socket? If I leave a battery connected to the socket, will it effectively flatten it when I turn the ignition off? I'll check with a meter.
Any replies (esp to the first point) much appreciated.
John
