Charging Systems: Generators: Description

Volkswagen manufactures generators for both 6 and 12 volt vehicles. Volkswagen generators are of the shunt-wound type. The field windings are wired in parallel with the armature winding. The most frequently used type of regulator is the two-unit regulator with declining characteristic curve. This regulator consists of a voltage regulating unit and a cutout relay. Another type of regulator is the variode regulator. In this type, a second voltage winding is installed on the voltage regulating unit instead of the current winding. If voltage regulator is found defective, unit should be replaced. The test specifications for Volkswagen regulators are given in the generator specification chart.
