Positions are low charge, high charge, dim and bright, as you observed. The low and high charge only mean anything if you still have a cutout relay on your generator instead of a regulator. On older tractors with the cutout, you manually regulated the charging rate. On high charge, the field connection of the generator is just grounded, giving maximum charge rate. On low charge, a resistor is in the circuit between the generator field connection and the ground, giving a lower charge rate. With a voltage regulator, the charge rate is automatically adjusted by the regulator and the low and high charge positions on the switch are just the same as an "off" position. Also, the manual regulation of the charging rate does not work very well. It's difficult to know where to set the charge rate, often leading to over or undercharging the battery with shortened battery life.
