S Terminal Circuit

S TERMINAL CIRCUIT


Description

The output voltage of the generator is controlled by the IC 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 regulator.

Diagnosis Procedure

Regarding Wiring Diagram information, Electrical Diagrams.
1.CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION
Check to see if connector F7 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 diagnostic station instruction manual.
2.CHECK VOLTAGE REGULATOR CIRCUIT





Check voltage between generator harness connector F7 terminal 3 and ground.

3 - ground : Battery voltage

Does battery voltage exist?
YES - Work Flow.
NO - Check harness for open between generator and fuse.
