Many
engine
manufacturers
specify
allowable
voltage
drops
in
the
cranking
circuit.
For
this
information,
refer
to
the
engine
manufacturer's
shop
manual.
c.
Inspect
all
control
switches
and
the
ignition
switch,
to
determine
their
condition.
Connect
a
jumper
lead
a-
round
any
switch
suspected
of
being
de-
fective.
If
the
system
functions
prop-
erly
using
this
method,
repair
or
re-
place
the
bypassed
switch.
d.
Ifspecified
battery
voltage
can
be
measured
at
the
motor
terminal
of
the
cranking
motor,
allowing
for
some
voltage
drop
in the
circuit
and
the
engine
is
known
to
be
functioning
properly,
re-

INSPECTION.
With
the
cranking
motor
removed
from
the
engine,
the
pinion
should
be
checked
for
freedom
of
operation
by
turning
it
on
the
screw
shaft.
The
armature
should
be
checked
for
freedom
of
operation
by
turning
the
pinion.
Tight,
dirty,
or
worn
bearings,
bent
armature
shaft,
or
loose
pole
shoe
screw
will
cause
the
armature
to
drag
and
it will
not
turn
freely.
If the
armature
does
not
turn
freely,
the
motor
should
be
disassembled
immediately.
However,
if
the
armature
does
operate
freely,
the
motor
should
be
given
electrical
tests
before
disassembly.

Connect
the
cranking
motor
in
series
with
a
fully
charged
battery
of
the
specified
voltage,
an
ammeter
capable
of
reading
several
hundred
amperes,
and
a
variable
resistance.
Also
connect
a
voltmeter
as
illustrated,
from
the
motor
terminal
to
the
motor
frame.
An
r.p.m.
indicator
is
necessary
to
measure
armature
speed.
