(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. 11-3)

If insulation is bad, replace stator with a new
one.

11-1-3 CHECKING ROTOR

(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.
