GENERATOR LIGHT ON WITH IGNITION OFF AND OR NO GENERATOR OUTPUT ON 1989 LEMANS WITH 2.0L
ENGINES (REPAIR PROCEDURE)
Models
Affected:
1989 LEMANS
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 1 MM 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" 2 MM fusible link with an eye terminal to fit the starter solenoid.
B.
Connect the fusible link to a 14" Long 6 mm 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.
