Inspection After Disassembly

INFOID:0000000001328253

PINION/CLUTCH CHECK

1.

Inspect pinion teeth.
• Replace pinion if teeth are worn or damaged. (Also check condition of ring gear teeth.)

2.

Inspect reduction gear teeth.
• Replace reduction gear if teeth are worn or damaged. (Also check condition of armature shaft gear

teeth.)

3.

Check to see if pinion locks in one direction and rotates smoothly in the opposite direction.
• If it locks or rotates in both directions, or unusual resistance is evident, replace.

CHARGING SYSTEM

System Description

INFOID:0000000001328254

The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times
• through 10A fuse (No. 33, located in the fuse and fusible link block)
• to alternator terminal 4 (“S” terminal).
“B” Terminal supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (“S” terminal) detecting the input voltage.
The charging circuit is protected by the 120A fusible link (VK45DE and VQ35DE AWD).
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 14, located in the fuse block (J/B)]
• to combination meter terminal 7 for the charge warning lamp.
Ground is supplied
• to combination meter terminal 2
• through alternator terminal 3 (“L” terminal)
• to alternator terminal 2 (“E” terminal) (VK45DE) or through case ground (VQ35DE)
• through ground E304 (VK45DE).
With power and ground supplied, the charge warning lamp will illuminate. When the alternator is providing suf-
ficient voltage with the engine running, 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.

MALFUNCTION INDICATOR

The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:
• Excessive voltage is produced.
• No voltage is produced.
