The polarity will be the same on both sides of the cutout, regardless of type. The voltage difference across it is the concern. Your readings would not be unusual for a regulator type, but the output at 6 volts is too low; it should be about 7.2V, as Tom says. A power diode such as used in the diode type will drop around 1.2 V at any current. Measure between the cutout contacts for the reading. Also check for any ground resistance between generator housing and battery ground post; there should be none.
