Stator Installation Notes
• Fit the stator coil lead grommet first. and the pickup coil
lead grommet into the notch of cover
securely.
e Route the stator coil leads in accordance w
ith
the Wire
Routing in the General Information chapter.
Alternator Rotor Cleaning Area
1. The tapered
portion
of the crankshaft.
2.

Stator Coil Removal
eRemove the alternator cover (see this chapter).
e Remove the holding
plate.
e
Unit
the pickup coil lead and stator coil lead grommets
out of the notch of
cover.
e Unscrew the mounting bolt, and take off the stator.
Alternator Inspection
There are three types of alternator
failures:
short, open
(wire burned out), or loss in rotor
magnetism.
A short or
open in one of the coil w
ires
will result in either a low
output,
or no output at
all.
A loss in rotor
magnetism,
which may be caused by dropp
ing
or
hitt ing
the
alternator,
by leaving it near an electromagnet
ic
field
,
or just by
aging,
will result in low output.
.To check the alternator output voltage, do the following
procedures.
Refer to the appropriate chapters and
charging system Wiring
Diagram.
Turn off the ignition sw
itch .
Disconnect connector 1.
Connect the hand tester (special
tool:
57001-983)
as shown in table.
Start the engine.
Run it at the rpm
given
in table.
Note the voltage readi ngs (total 3
measurements).

*If the output voltage shows the value in
table,
the
alternator operators properly and the regulator/rectifier
is damaged. A much lower reading than that given in
the table indicates that the alternator is defective .
• Check the stator coil resistance as
follows:
Stop the engine.
