2.
Inspecting the field coil.
a.
Check for conduction between slip rings. If there
is no conduction, the field
coil is suspected
to
be
broken.
Replace the field coil.
b.
Check for conduction between a slip ring and
shaft (or core).
If any conduction is found, the
field coil is suspected
to
be poor in insulation.
Replace
the field coil.
3.
Inspecting the stator coil.
a.
Check for conduction between lead wires of the
stator
coil. If there is no conduction, the stator
coil is suspected
to
be broken. Replace the
stator coil.
b.
Check for conduction between each lead wire
and stator core.
If any conduction is found, the
stator
coil is suspected
to
be poor in insulation.
Replace
the stator coil.
