All models utilize an integral regulator charging system. The integrated circuit (IC) regulator is a solid state unit that is mounted inside the generator to the rear end frame. All regulator components are enclosed in a solid mold to protect them from the heat and corrosive elements. The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication. Two brushes carry current through two slip rings to the field coil, mounted on the rotor. Stator windings are assembled inside a laminated core that forms part of the generator drive end frame. A rectifier bridge that contains six diodes is connected to the stator windings. These diodes electrically change stator AC voltage into DC voltage. This DC voltage is then transmitted to the generator output terminal. Two neutral diodes are utilized to smooth out voltage fluctuations caused by varying generator speeds. A capacitor (condenser), mounted in the regulator, protects the rectifier bridge and neutral diodes. This capacitor also suppresses radio interference noise.
