Why does my meter only show 12 V?
The power line is 127 V but after the capacitive coupling and then loading by the meters input impedance you only get 12 V. In short, this is all expected, and actually shows you have a good meter. What Olin said, but also you have capacitive coupling because any two conductors not touching is a capacitor.
