Alternator Stator Removal
•
Remove:
Alternator Cover (see Alternator Cover Removal)
Crankshaft Sensor [A] (see Crankshaft Sensor Re-
moval)
Bolts [B] and Alternator Stator [C]
Alternator Stator Installation
•
Tighten:
Torque - Alternator S tator Bolts: 13.5 N ·m (1.4 kgf·m, 119
in·lb)
•
Install:
Crankshaft Sensor (see Crankshaft Sensor Installation)
•
Fit the lead grommets into the notch on the alternator
cover.
Grommets [A] for Alternator Leads
Grommets [B] for Crankshaft Sensor Leads
○
Run the alternator starter leads under the crankshaft sen-
sor leads.
○
Fit the grommet for alternator leads first and then install
the one of crankshaft sensor leads to the notch of the
alternator cover.
Regulator/Rectifier Output Voltage Inspection
•
Remove the seat (see Seat Removal in the Frame chap-
ter).
•
Check the battery condition (see Battery section).
•
Warm up the engine to obtain actual alternator operating
conditions.
•
Check that the ignition switch is turned off, and connect a
hand tester to the battery terminals.
Special Tool - Hand Tester: 57001-1394
•
Start the engine and note the voltage readings at various
engine speeds with the headlight turned on and then off.
The readings should show nearly battery voltage when
the engine speed is low, and as the engine speed in-
creases, the readings should also increase.

•
Turn off the ignition switch, and disconnect the hand
tester.
If the regulator/rectifier output v oltage is between the val-
ues given in the table, the c harging system is working nor-
mally.
If the output voltage is much higher than the values spec-
ified in the table, the regulator/rectifier is defective or the
regulator/rectifier leads are loose or open.
