30.2.2 Field coil
1. Test for continuity between the slip rings as shown
in the illustration. No continuity shows there is an
open circuit in the field coil. Replace the field coil.
2. Test for no continuity between the slip ring and
shaft (or core) as shown in the illustration. Any
continuity shows there is a grounded circuit in the
field coil. Replace the field coil.
30.2.3 Stator core
1. Test for continuity between the leads as shown in
the illustration. No continuity shows there is an
open circuit in the stator core. Replace the stator
core.
