Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Alternator & Regulator: Description
The CS130 and CS144 (Charging System) alternators have a high amperage output. The 130 or 144 designation is the outside diameter of the stator laminations, measured in millimeters. This alternator series also has an integral regulator but does not have a diode trio. See Fig 1 . The delta wound stator, rectifier bridge, rotor with slip rings, and brushes are similar to other alternators. A conventional fan and pulley are used. An internal fan cools the slip rings, end frame, rectifier bridge and regulator.
The CS130 alternator should not be disassembled for any reason. The alternator requires no periodic maintenance or adjustment and can not be serviced. The CS144, is serviceable. For model application, see the ALTERNATOR IDENTIFICATION & OUTPUT table.
