2. CHECK “B” TERMINAL CIRCUIT
Check voltage between alternator “B” terminal and ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open between alternator and fusible
link.
3. CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive terminal and alternator
“B” terminal.
OK or NG
OK >> Go to SC-22, "Trouble Diagnoses with Starting/Charging
System Tester (Charging)" .
NG >> Check harness between battery and alternator for poor continuity.

Removal and Installation NKS0000H
REMOVAL
1. Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal.
CAUTION:
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent
any interference between the window edge and the vehicle when the door is opened/closed. Dur-
ing normal operation, the window slightly raises and lowers automatically to prevent any window
to vehicle interference. The automatic window function will not work with the battery discon-
nected.
2. Remove engine undercover, using power tools.
3. Remove air cleaner assembly and harness clip. Refer to EM-15, "
AIR CLEANER AND AIR DUCT" .
4. Remove radiator cooling fan assembly. Refer to CO-21, "
COOLING FAN" .
5. Remove alternator and power steering oil pump belt. Refer to EM-12, "
Removal and Installation" .
6. Disconnect alternator connector (1).
7. Remove “B” terminal mounting nut (2).
8. Remove the harness bracket bolts (A).

9. Remove oil pressure switch harness clip (C) from alternator stay
(1).
10. Disconnect oil pressure switch connector (D) and oil tempera-
ture sensor connector (E).
11. Remove alternator mounting bolt (B) and alternator stay mount-
ing bolt (F) using power tools, then remove alternator stay.
12. Remove alternator mounting bolt (A), using power tools.
13. Remove alternator assembly downward from the vehicle.
ALTERNATOR PULLEY INSPECTION
Perform the following.

Make sure that alternator pulley does not rattle.

Make sure that alternator pulley nut is tight.
INSTALLATION
Installation is the reverse order of removal.

Install alternator, and check tension of belt. Refer to EM-12, "Checking Drive Belts" .
CAUTION:
Be sure to tighten “B” terminal nut carefully.
