(3)Check the insulation resistance between sta- tor core and each stator lead using a Dr. Robin generator tester in megger tester mode or a megger tester. (Fig.
If insulation is bad, replace stator with a new one.

(1) Remove rear cover and stator.
(2) Using a Dr. Robin or a circuit tester, measure |

the resistance of the field coil at the terminals. |

NOTE : Because a diode is soldered to the coil ends at the terminals, resistance may be mea- sured only when tester probes touch the termi- nals in one combination of polarity. Therefore, if no resistance reading appears, try checking in reverse polarity.
[Remedy]
If the resistance is not normal, replace rotor with a new one.
