GENERATOR LIGHT ON W/ IGNITION OFF AND NO CHARGE

Subject: GENERATOR LIGHT "ON" WITH IGNITION OFF AND/OR NO GENERATOR OUTPUT

MODELS AFFECTED 1989 PONTIAC LEMANS WITH 2.0L LT2 ENGINE

General Motors has determined that some 1989 Pontiac LeMans with 2.0L TBI Engine (RPO LT2) 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, dealer will revise the generator output wires,

VEHICLES INVOLVED

Involved are certain 1989 Pontiac LeMans produced within the following VIN breakpoints: Up To And Year Plant Beginning Including

1989 Pupyong KB315641 KB368546

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

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.
