Alternator - DELCO W/Integral Regulator: Description
There are 2 types of alternators used on these vehicles. The SI series integral regulator alternators features an external 2-terminal connector on alternator.
The CS series integral regulator features an external 4-terminal connector on alternator. The SI and CS use a solid state regulator mounted inside alternator housing. These alternators are available with different outputs at idle and maximum capacity.
SI and CS series alternators consist of 2 end frame assemblies (housing), rotor, stator, brushes, slip rings and diodes. Rotor is supported in drive end frames by ball bearings and in slip ring end frame by roller bearings. Bearings contain enough lubrication to eliminate need for periodic lubrication.
