check
(Paragraph 5-S) should
be
made.
This
check
is
suitable
for.incoming
inspection.
If
a
fault
is
detected
in
the
power
supply
while
making
the
performance check
or
during normal
operation,
pro-
ceed
to
the
troubleshooting procedures
(Paragraph
5-51). After troubleshooting and
repair
(Paragraph

to
normal
operation,
repeat
the
performance
check
to
ensure
that
the
fault
has
been
properly
corrected and
that
no
other
faults
exist.
