All models feature a solid state regulator mounted inside the alternator. The construction and operation of all models is basically the same. Delcotron alternators consist primarily of 2 end frame assemblies, rotor, stator, brushes, slip rings and diodes. The rotor is supported in the drive end frame by ball bearings and in the slip ring end frame by roller bearings. The bearings are sealed and do not require periodic lubrication.
