S TERMINAL CIRCUIT

Diagnosis Procedure

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 Technical Service Bulletin.
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 >> Refer to See: Initial Inspection and Diagnostic Overview\Work Flow.
NO >> Check harness for open between generator and fuse.
