armature short circuits. As the armature
revolves in the growler, hold a steel strip
(such as a hacksaw blade) above it. The
blade will vibrate above the area of the
armature core on which the short circuit is
located.
(2)
Use a 110 volt test lamp with test
points to detect grounds. Place one test
point on the armature core or shaft and the
other on the commutator. If the lamp lights,
the armature is grounded.
h.
Field Coil Test. Test field coil insulation
resistance with megger connected between frame
and one coil terminal. Minimum resistance
reading permissible is one megohm.
i.
Solenoid Test. Disconnect all leads from the
solenoid and make test connections as shown in
figure 13-6.
(1)
To check the hold-in winding,
follow connections shown in solid line.
(2)
Use the carbon pile to adjust the
voltage to 20 volts. Voltmeter shall read 20
V DC and ammeter shall read 6.1 to 6.8
amps. A high ammeter reading indicates a
shorted or grounded hold-in winding. A low
reading indicates excessive resistance.
