2. Set the armature in a growler.
CAUTION
Clean the surface of the armature thoroughly
before performing the test.
3. While holding a thin strip of iron against the
armature in parallel with its axis, turn the armature
slowly. The armature is normal if the iron strip is
not attracted to the armature or it does not vibrate.
4. Check the insulation between commutator
segments and armature coils. The armature coils
are properly insulated if no continuity is present.
5. Check continuity between a segment and another.
There is no open circuit in the tested coil if there is
continuity.

1. Coil open circuit test
• Check that there is continuity between the M
terminal and body A.
• If there is no continuity, replace the magnetic
switch.
2. Contact fusion check
• Check that there is no continuity between the B
terminal and M terminal.
• If there is continuity, replace the magnetic switch.
3. Switch contact check
• Push the indicated end of the magnetic switch
with a strong force to close the internal contacts.
Without releasing the switch end, check that
there is continuity between the B terminal and M
terminal.
• If there is no continuity, replace the magnetic
switch.
