S Terminal Circuit

S TERMINAL CIRCUIT

Description

The output voltage of the generator is controlled by the IC voltage regulator at terminal "3" (S) detecting the input voltage.
Terminal "3" circuit detects the battery voltage to adjust the generator output voltage with the IC voltage regulator.


Diagnosis Procedure

Regarding Wiring Diagram information, Electrical Diagrams.

1. CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION

1.Turn ignition switch OFF.
2.Verify generator connector F1 terminal 3 is clean and tight.
Is the inspection result normal?
YES- GO TO 2.
NO- Repair terminal connection. Confirm repair by performing complete Starting/Charging system test.
Refer to Multitasking Battery Diagnostic Station instruction manual.

2. CHECK VOLTAGE REGULATOR TERMINAL CIRCUIT

Check voltage between generator harness connector F1 terminal 3 and ground.





Is voltage as specified?
YES- Work Flow.
NO- Check harness for open between generator and fuse.
