• To check the alternator output voltage, do the following
procedures.
○ Turn the ignition switch to OFF.
○ Remove the left frame cover (see Frame Cover Removal
in the Frame chapter).
○ Pull out the alternator lead connector [A] from the bracket
and disconnect it.
○ Open the clamp [B].
○ Connect the hand tester as shown in the table 1.
Special Tool - Hand Tester: 57001-1394
○ Start the engine.
○ Run it at the rpm given in the table 1.
○ Note the voltage readings (total 3 measurements).

Another White lead 42 V or more
If the output voltage shows the value in the table, the al-
ternator operates properly.
If the output voltage shows a much lower than the value
in the table, the alternator is defective.
• Check the stator coil resistance as follows.
○ Stop the engine.
○ Connect the hand tester as shown in the table 2.
○ Note the readings (total 3 measurement).

If there is more resistance than shown in the table, or no
hand tester reading (infinity) for any two leads, 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 highest resistance range of the hand tester,
measure the resistance between each of the white leads
and chassis ground.
Any hand tester reading less than infinity (∞) indicates a
short, necessitating stator replacement.
If the stator coils have normal resistance, but the voltage
checkshowedthealternatortobedefective; thentherotor
magnets have probably weakened, and the rotor must be
replaced.

检查发电机的输出电压，进行以下工作
程序。
○打开点火开关关闭。
○拆卸左框盖（见框盖拆卸
在框架章）。
○拉出发电机引线接头[支架]
断开。
○打开夹[ b ]。
○连接手机如表1所示。
专用工具-手机：57001-1394
○启动发动机。
○运行它在表1中给出的转。
○注意电压读数（总3次）。
