Check the insulation resistance between

stator core and each stator lead using a
Dr.
Robin generator tester
in
msgger tester mode
or
a megger tester.

insulation
is
bad, replace stator with a new
one.

NOTE
1
:
Because a diode is soldered to the coil
ends at the terminals, resistance may
be measured only when tester probes
touch the terminals 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
I
new one.
