General Motors of Canada has determined that certain 1989 Optima with 2.OL engines may develop a condition whereby the generator light stays on with the ignition off or has no generator output. The fusible link may overheat and cause loss of insulation from adjacent wires. This may result in an electrical short between the generator output lead and lamp wire causing a regulator failure.
To prevent the possibility of this condition occurring, dealers will revise the generator output wires.
Involved are certain 1989 Optima produced within the following VIN breakpoints:
YEAR PLANT FROM THROUGH OPTIONS ---- ----- ---- ------- ------- 1989 Pupyong SOP EOP 2.0L Engine (RPO LT2)
All affected vehicles have been identified by the VIN listing provided to involved dealers with this bulletin. Any dealer not receiving a listing was not shipped any of the affected vehicles.
Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of kilometres traveled, age of vehicle, or ownership, from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required modification according to instructions contained in this bulletin.
Refer to Section 4 of the Service Policies and Procedures Manual for the detailed procedure on handling Product Campaigns. Dealers are requested to complete the campaign on all transfers as soon as possible.
All owners of record at the time of campaign release are shown on the attached computer listing and have been notified by first class mail from General Motors. The listings provided are for campaign activity only and should not be used for any other purpose.

1. Disconnect positive battery cable.
2. Remove the generator output wire and cut it off even with the conduit. Save the end for terminal size.
3. Cut off the voltage regulator sense wire (red) from the two pin generator connector and cut the remaining wire even with the conduit. The regulator does not need this wire and can sense voltage from the output wire.
4. Unbolt the 1MM fusible link generator output wire from the starter solenoid and cut if off even to the conduit. Save the end for terminal size.
5. Make a new generator output wire:
A. Use a 6" 2MM fusible link with an eye terminal to fit the starter solenoid.
B. Connect the fusible link to a 14" long 6MM or 8 gauge wire. Solder the connection and tape over with high temperature tape.
C. Install an eye terminal to fit the generator output stud.
D. Cover complete wire except fusible link with a length of plastic conduit and tape in place.
6. Install new generator output wire and tie-strap in place.
7. Install positive battery cable and two pin generator connector. With ignition on, the generator light should be on.
Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
