Description

The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the ignition switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running, the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

Diagnosis Procedure

1.CHECK “L” TERMINAL CONNECTION

2.CHECK “L” TERMINAL CIRCUIT (OPEN)

3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

4.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

5.CHECK POWER SUPPLY CIRCUIT
