CHARGING SYSTEM
System DescriptionINFOID:0000000005929019
The generator provides DC voltage to operate the vehicl e's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to generator terminal 3 through
• 10A fuse (No. 29, located in the fuse and fusible link box).
Power is supplied through terminal 1 to charge the batte ry and operate the vehicle's electrical system. Output
voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120A fusible link
[letter a , located in the fusible link box (battery)].
Ground is supplied
• to generator terminal 5
• through body ground F5, and
• through the generator case to the cylinder block
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 3, located in the fuse block (J/B)]
• to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the generator.
When the ignition is turned on and power becomes availabl e at terminal 2, this "wakes up" the regulator. The
regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With
power and ground supplied, the charge warning lamp will il luminate. When the generator is providing sufficient
voltage, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

2.CHECK CHARGE WARNING LAMP CIRCUIT
1. Disconnect generator connector F1.
2. Apply ground to generator connector F1 terminal 2 with the igni- tion switch in the ON position.
OK or NG
OK >> GO TO "WORK FLOW" .
NG >> Check the following. • 10A fuse [No. 3, located in fuse block (J/B)]
• CHARGE lamp
• Harness for open or short between combination meterand fuse
• Harness for open or short between combination meter and generator
DIAGNOSTIC PROCEDURE 2
Check Battery Circuit
1.CHECK BATTERY CIRCUIT CONNECTION
Check to see if terminal 1 is clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair terminal 1 connection. Confirm repair by performing complete Starting/Charging system test. Refer to diagnostic station instruction manual.
2.CHECK BATTERY CIRCUIT
Check voltage between generator connector F2 terminal 1 and
ground using a digital circuit tester.
OK or NG
OK >> GO TO 3.
NG >> Check the following. • 120A fusible link [letter a , located in fusible link box
(battery)]
• Harness for open or short between generator and fus- ible link
3.CHECK VOLTAGE DROP ON BATTERY CIRCUIT
Check voltage between generator connector F2 terminal 1 and bat-
tery positive terminal using a digital circuit tester.
OK or NG
OK >> Replace the generator. Refer to SC-25, "Removal and
Installation" . Confirm repair by performing complete
Starting/Charging system test. Refer to diagnostic sta-
tion instruction manual.
NG >> Check harness between the battery and the generator for poor continuity.
DIAGNOSTIC PROCEDURE 3
Check Voltage Regulator Circuit
CHARGE lamp should light up.
