TEST
PERFORMANCE TEST
Starter
motor
should be
subjected
to
a
no
load
test
whenever
it
has
been overhauled
to
ensure
that its
performance
will be
satisfactory
when
installed
on
engine
Starter
motor
should also be
subjected
to
the
test
when the
cause
ofabnormal
operation
is to
be determined
A brief outline of
the
test is
given
below
