GEN. LIGHT ON W/IGN. OFF AND OR NO GEN. OUTPUT. Pontiac LeMans 1989

For 1990-2009 cars

# GEN. LIGHT ON W/IGN. OFF AND OR NO GEN. OUTPUT

#### Models Affected: 1989 LEMAMS

Condition: The generator output wire going to the starter solenoid may be shorted to the generator light wire.

Diagnosis: Remove the two terminal connector at the generator. If the generator light is still on with the ignition off then there is a short between the two wires going to the solenoid.

#### Repair Procedure:

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 it 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 gage 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.

If no light, test brown wire for voltage. If none, brown wire may be open and need repair. If there is voltage then regulator may have been damaged from the short, replace generator.

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.
