There is another thread here where we believe people's antenna booster was wired to the wrong side of a 12V light. Switched on the ground side, power would be available (in series through the bulb) until the light was switched on. Then that side would be ground and the booster got zero volts. Black means ground in 12V circuits, but hot in 120 vac circuits. That is my theory where the miswiring occurred.
