Subsection 05 (ELECTRIC STARTER)
Test for Ground Circuit in the Armature
Use growler test probes. Check between arma-
ture core and the commutator bars. If growler
lamp turns on, bars are grounded. If so, replace
armature.

Test Armature for Shorted Winding
When the armature is rotated in the growler with a
steel strip (hacksaw blade) held above it, the strip
will vibrate over that area of the armature which
has short circuit. Replace armature if so.

Test the Armature for Open Circuit
Use growler test probes. Place one test probe
on a commutator bar and the other test probe
on the neighboring bar. Repeat this operation for
all bars, moving one test probe at a time. If the
growler lamp does not turn on, the armature cir-
cuit between these 2 bars is opened. The arma-
ture should be replaced or repaired; open circuits
most often occur at the commutator riser where
coils are soldered. (Burnt commutator bars are
usually an indication of an open-circuit armature
coil.)

Test the Field Winding for Open Circuit
Use growler test probes. Place one test probe on
the negative brush and the other test probe on the
yoke. If growler lamp does not turn on, the field
winding has an open-circuit. The yoke has to be
repaired or replaced.

1. Test probes
Check the dynamic brake winding for open circuit
by placing one test probe on the positive brush and
the other probe on the negative brush.
If growler lamp does not turn on, the winding cir-
cuit is open-circuit and the starter housing has to
be repaired or replaced.
