how does your ohmmeter move? or the multimeter you used to check the ".06 volts"? > electrons
current flows from the power source thru the gauge to the ground, the amount of current flowing being controlled by the resistance of the sender .... the gauge has small coils inside that act like electro-magnets to pull the needle across
