REMEDY
Check and recharge if
necessary.
Refer to electrical wiring
diagram and check all
wiring.
Replace faulty unit.
—CAUTION—
Do not use coarse sand
paper or emery cloth. After
seating, clean thoroughly to
remove all sand and metal
particles to prevent ex-
cessive wear. Keep motor
bearing from sand or
metal particles.
Brushes should be a free fit
in the brush boxes without
excessive side play. Binding
brushes and brush boxes
should be wiped clean with
a gasoline (undoped) moist-
ened cloth. A new brush
should be run in until at
least 50 percent seated;
however, if facilities are not
available for running in
brushes, then the brush
should be properly seated
by inserting a strip of num-
ber 000 sandpaper between
the brush and commuta-
tor, with the sanded side
next to the brush. Pull sand
paper in the direction of ro-
tation, being careful to keep
it in the same contour as the
commutator.
