Nissan Sentra Service Manual: S terminal circuit

Description

The output voltage of the generator is controlled by the IC regulator at terminal “S” detecting the input voltage from battery.

The “S” terminal circuit detects the battery voltage to adjust the generator output voltage with the IC voltage regulator.

Diagnosis procedure

Regarding wiring diagram information. Refer to chg-9, "wiring diagram".

1.Check “s” terminal connection

  1. Turn ignition switch OFF.
  2. Check if “s” terminal is clean and tight.

No >> repair “s” terminal connection. Confirm repair by performing complete charging system test using exp-800 ni or gr8-1200 ni (if available). Refer to the applicable instruction manual for proper testing procedures.

2.Check “s” terminal circuit

Check voltage between generator harness connector and ground.
