11. See Figure 5-21. Check for OPEN ARMATURE with an
ohmmeter or continuity tester.
a. Check for continuity between all commutator seg-
ments (1).
b. There should be continuity (0 ohms) at all test
points. No continuity at any test point indicates
armature is open and must be replaced.
12. See Figure 5-22. Check for GROUNDED FIELD COIL
with an ohmmeter or continuity tester.
a. Touch one probe to the frame (1).
b. Touch the other probe to each of the brushes (2)
attached to the field coil.
c. There should be no continuity (infinite ohms). If
there is any continuity at either brush, then the field
coil(s) are grounded and the field frame must be
replaced.
13. See Figure 5-23. Check for OPEN FIELD COILS with an
ohmmeter or continuity tester.
a. Touch one probe to the field wire (1).
b. Touch the other probe to each of the brushes
attached to the field coil(s) (2).
c. There should be continuity (0 ohms). If there is no
continuity at either brush, then the field coil(s) are
open and the field frame must be replaced.
14. See Figure 5-24. Test BRUSH HOLDER INSULATION
with an ohmmeter or continuity tester.
a. Touch one probe to holder plate (1).
b. Touch the other probe to each of the positive (insu-
lated) brush holders (2).
c. There should be no continuity (infinite ohms). If
there is continuity at either brush holder, replace the
brush holder assembly.
