Generator and Engine Wiring Harness - Design Changes
BULLETIN NO.: 97-T-22ISSUE DATE: June, 1997
GROUP/SEQ. NO.: Electrical-03
CORPORATION NO.: 786401
SUBJECT:
Service Information on Generator and Engine Wiring Harness Design Changes
MODELS AFFECTED:
1991-1997 Saturns
PURPOSE:
This bulletin provides information on a design change of the generator assembly and engine wiring harness, and the impact these changes have on servicing the vehicle.
GENERATOR ASSEMBLIES
Saturn vehicles now use three different generator assemblies. The chart shows the usage for these three generators.
The information shown describes the differences in the physical appearance, service diagnostics, and removal and installation procedures of the CS121D generator.
Physical Appearance
The CS121D generator uses a different electrical connector, requires no generator splash shield, and has dual internal fans.
Service Diagnostics
Follow the service diagnostic procedure within the Electrical Service Manual except for the following difference:
A good CS121D generator will provide a minimum output greater than 63 amps when performing the generator output test on the Saturn electrical system tester (5A9154Z).
Special Service Tools
Both the CS121D generator and the CS130 generator require the use of output stud wrench (5A9401C) when removing the fusible link wire.
NOTICE:
If the B+ stud is not held with the output stud wrench (SA9401C), and B+ stud rotates, the insulator may break causing the generator to fail.
ENGINE WIRING HARNESS
The engine wiring harness used with the CS121D generator was changed to accommodate the new generator connector. Generator connector kit P/N 21024414 and lead kit P/N 12116713 are available for harness repairs.
