All the back of the lighter is fine. what i am talking about is the front side now. When i put a test light in the hole where your cell phone charger plugs into I had power in the bottom , dead center on a center brass circle. BUT I found a shiny metal piece that was about to get lost. I have never looked inside a cig lighter before, i just slam chargers, etc in them and expect them to work. question is this, is there anything under this shiny tab that touches the brass center? A spring or something or do you know? Thanks for the help, the XF future in our home is looking brighter.
