Charging System
Check the alternator output voltage, do the following pro-
cedures.
Remove:
Left Side Cover (see Side Cover Removal in the Frame
chapter)
Seat (see Seat Removal in the Frame chapter)
Clear the leads from the clamp [A].
Connect a tester to the connector [B] as shown in the table
1, using the needle adapter set.
Start the engine.
Run it at the rpm given in the table 1.
Note the voltage readings.
Special Tool - Needle Adapter Set: 57001-1457
Table 1, Alternator Output Voltage
Connections
Tester (+) to
White lead
If the output voltage shows the value in the table, the al-
ternator operates properly.
If the output voltage shows 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.
Disconnect the alternator lead connector.
Connect the tester [A] to the connector [B] as shown in
the table 2.
Note the readings.
Table 2, Stator Coil Resistance
Connections
Tester (+) to
White lead
If there is more resistance than shown in the table, or no
tester reading (∞) the stator has an open lead and must
be replaced. Much less than this resistance means the
stator is shorted, and must be replaced.
Using the tester, measure the resistance between each
leads and chassis ground.
Any tester reading less than infinity (∞) indicates a short,
necessitating stator replacement.
If the stator coils have normal resistance, but the voltage
check showed the alternator to be defective; then the rotor
have probably weakened, and the rotor must be replaced.
