ENGINE ELECTRICAL 6D – 3

GENERAL DESCRIPTION
GENERATOR STARTER MOTOR



066L300004 065L300002

The basic charging system is the IC integral regulator charging system. The internal components are connected
electrically as shown in charging circuit diagram.
The generator features a solid state regulator that is mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brush holder assembly is attached to the slip ring end frame.
The generator voltage setting cannot be adjusted.
The starter motor circuit is composed of a 4-pole 4-brush type direct current series motor. The starter motor circuit
utilizes negative ground polarity.
