Date: March, 1995
Subject:
Dim Headlamps, Slow Windshield Wipers, etc., Resulting from Low/No Generator Output (Retrofit with CS-144 Generator)
Models:
1992-94 Buick LeSabre, Park Avenue
1992-94 Oldsmobile Eighty Eight, Ninety Eight

CONDITION
Some owners may comment on such conditions as dim headlamps, slow windshield wipers, etc. After testing, it is confirmed that the generator has low
or no output.
CAUSE
In some high temperature applications, it has been determined that the CS-130 and CS-130 Dual Internal Fan (DIF) generators cannot perform with
reliability to meet owner expectations.
CORRECTION
The CS-144 retrofit has been devised to increase durability and performance.
Replace the following components:
1.
The CS-130 and CS-130 DIF generators with the 140 amp CS-144 generator, P/N 10463625.
Important:
The CS-144 generators listed above will include: the output terminal plastic cap, P/N 3523277, and the output terminal nut, P/N 11502811.
These parts can be ordered from GMSPO if they are not with the generator.
2.
The regulator connector, P/N 12117361, (for vehicles equipped with CS-130 DIF generator only).
3.
The positive battery cable/generator output wire assembly with P/N 12164880 (on models with L27 engine) and P/N 12164881 (on models with
L67 engine).
4.
The accessory drive belt with P/N 24504258 (on models with L27 engine) and P/N 24504257 (on models with L67 engine).
REPLACEMENT
