Electrical
Test
Equipment
Many
of
the
electrical
tests
described
in
this
manual
call
for
measuring
voltage,

a
digital
multi-
meter
(DMM)
.
Digital
meters
are
preferred
for
precise
mea-
surements
and
for
electronics
work
because
they
are
generally
more
accuratethan
analog
meters
.
The
numerical

is
alsoless
likely
to
be
misread,
since
there
is
no

to
be
misinterpreted
by
reading
at
an
angle
.
An
LED
test
light
is
a
safe,
inexpensive
tool
that
can
be
used
to
perform
many
simple
electrical
tests
that
would
otherwise
require
a

A

if
you

them
.
Wire

in
the

indicate
a
multi-colored

For

the

BLU/RED
indicates
a
Blue

Many
electrical

using
a

Each

Cleaning
Problems
Common
cleaning
problems
with
thewipers
includestreak-
ing
or
sheeting,
waterdrops
after
wiping,
and
blade
chatter
.
Streaking
is
usually
caused
when
wiper
blades
are
coated
with
road
film
or
car
wash
wax
.
Clean
the
blades
using
soapy
water
.
If
cleaning
does
not
cure
the
problem,
the
blades
should
be
replaced
.
BMW
recommends
replacing
the
wiper
blades
twice
a
year,
before
and
after
the
cold
season

Wiper
blade
chatter
may
be
caused
by
dirty
or
worn
blades,
or
by
wiper
arms
that
areout
of
alignment
.
Clean
the
blades
and
windshield
as
described
above
.
Adjust
the
wiper
arm
so
that
there
is
even
pressure
along
the
blade,
and
so
that
the
blade
at
rest
is
perpendicular
to
the
windshield
.
If
problems
persist,
theblades
and
wiper
arms
should
be
replaced
.
The
wiper
blades
can
be
renewed
in
one
of
two
ways
:
either
by
replacing
the
complete
blade
or
by
replacing
just
therubber
insert
.
Insert
replacement
is
the
mosteconomicalmethod,
al-
though
overtime
the
wiperblade
itselfwill
become
worn
.
One
ruleof
thumb
wouldbe
to
replace
just
the
inserts
