Re: Model A Electrical Inquiry re: cut out
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.
