Hello experts. In a house with its original general lighting circuitry in 2 wire romex, I changed the first plug of each circuit to GFCI in order to convert the plugs to 3wire as is often done. Can anyone tell me why the plug and switch device yokes of these 2wire circuits now measure between 4 and 7 volts to ground? I measured from the device yokes to a remote ground path such as the ground of newer (grounded) circuits.
