CHARGING SYSTEM
Revision: 2004 November 2004 FX35/FX45
DIAGNOSTIC PROCEDURE 4
Check “B” Terminal Circuit
1. CHECK “B” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check to see if “B” terminal is clean and tight.
OK or NG
OK >> GO TO 2. Confirm repair by performing complete Battery/Starting/Charging system test.
NG >> Repair “B” terminal connection.
2. CHECK ALTERNATOR “B” TERMINAL CIRCUIT
Check voltage between alternator B terminal E307 terminal 1 (B/R)
and ground using a digital circuit tester.
OK or NG
OK >> GO TO 3.
NG >> Check the following.

120A fusible link [fusible link holder (VK45DE and
VQ35DE AWD)]

Harness for open or short between alternator and fus-
ible link (VK45DE and VQ35DE AWD)

Harness for open or short between alternator and battery (VQ35DE 2WD)
3. CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start the engine.
2. When the engine running at idle and warm, check voltage
between alternator B terminal E307 terminal 1 (B/R) and battery
positive terminal using a digital circuit tester.
OK or NG
OK >> GO TO 4.
NG >> Check harness between the battery and the alternator
for poor continuity.
4. CHECK ALTERNATOR DRIVE BELT TENSION
1. Turn ignition switch OFF.
2. Check alternator drive belt tension. Refer to EM-169, "
Checking Drive Belts" (VK45DE) or EM-15,
"Checking Drive Belts" (VQ35DE) in “ENGINE MECHANICAL (EM)” section.
YES or NO
YES >> Replace the alternator. Confirm repair by performing complete Battery/Starting/Charging system
test.
NO >> Readjust drive belt tension. Refer to EM-169, "
Tension Adjustment" (VK45DE) or EM-15, "Te n -
sion Adjustment" (VQ35DE) in “ENGINE MECHANICAL (EM)” section. Battery voltage should exist.

DIAGNOSTIC PROCEDURE 5
Check “S” Terminal Circuit
1. CHECK “S” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check to see if “S” terminal is clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair “S” terminal connection. Confirm repair by performing complete Battery/Starting/Charging
system test.
2. CHECK ALTERNATOR “S” TERMINAL CIRCUIT
Check voltage between alternator harness connector E311
*1 or
F26
*2 terminal 4 (LG) and ground using a digital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 3.
NG >> Check the following.

10A fuse (No. 33, located in fuse and fusible link box)

Harness for open or short between alternator and
fuse
3. CHECK “S” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start the engine.
2. When the engine running at idle and warm, check voltage
between alternator connector E311
*1 or F26*2 terminal 4 (LG)
and battery positive terminal using a digital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> Replace the alternator. Confirm repair by performing
complete Battery/Starting/Charging system test.
NG >> Check harness between the battery and the alternator for poor continuity.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate “CHARGE” warning lamp, if any of the following
symptoms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.Battery voltage should exist.
