FINAL
STEPS
You

soldered
properly.
Check
for
loose
lumps
of
solder
and
straighten
out
the
wiring
and
components
so
that
there
are
no
accidental
shorts.
2)
The
flowing
of
rosin
between
switch
contacts
causes
leakage.
by
briskly
cleaning
the
area
between
the
contacts
with
a
stiff
brush
saturated
with
carbon
tetrachloride.
