GENERAL
The
convertible
top
comes
in
three
versions
:
a
manually
op-erated
top,
a
semi-automatic
power
top
and
a
fully
automatic
power
top
.
NOTE-
The
convertible
top
control
module
(CVM)
is
located
behind
the
left
rearside
trim
panel
.
For
the
location
of
other
convertible
top
electric
components
see610
Electrical
Component
Locations
.
The
rear
window
in
the
convertible
models
is
made
of
a
strong,
flexible
vínyl
which
is
available
separately
.
Replace-
ment
of
the
rear
window
is
not
covered
in
this
manual
.
The
left
and
right
visor
latch
plates
can
be
accessed
by
re-
moving
the
trim
and
moldings
around
the
sides
and
top
of
the
windshield
.
Each
latch
is
secured
to
thetop
of
the
windshield
usingthree
bolts
.
Latch

is
adjusted
as

for
the

which,
in
conjunction
with
the
mass
of
the

in
the
lug-

compartment,
serves
to

CAUTION-
The

convertible
requires
a
specialbattery

which
is
designed
for
constant
vibration
.
A

.
Height
of
a
latch
can
be
changed
by
using

.
To

it
is
necessary
to

GENERAL
Electrical
System
Safety
Precautions
A
brief
description
of
the
principal
parts
of
the
electrical
sys-
tem
is
presented
here
.
Also
covered
here
are
basic
electrical
system
troubleshooting
tips
.
Voltage
and
Polarity
The
vehicle
electrical
system
is
a
12-volt
direct
current
(DC)
negative-ground
system
.
A
voltage
regulator
controls
system
voltage
at
approximately
the
12-volt
rating
of
the
battery
.
Al¡
circuits
are
grounded
by
direct
or
indirect
connection
to
the
negative
(-)
terminal
of
the
battery
.
A
number
of
ground
con-
nections
throughout
the
car
connect
the
wiring
harness
to
chassis
ground
.
These
circuits
are
completedby
the
battery
cable
or
ground
strap
between
the
body
and
the
battery
nega-
tive
(-)
terminal
.
Wiring,
Fuses
and
Relays
Nearly
all
parts
of
the
wiring
harnessconnect
to
compo-
nents
of
the
electrical
system
with
keyed,
push-on
connectors
that
lock
into
place
.
Notable
exceptions
arethe
heavy
battery
cables
and
the
starter
wiring
.
The
wiring
is
color-coded
for
cir-
cuitidentification
.
With
theexception
of
the
battery
charging
system,
most
electrical
power
is
routed
from
the
ignition
switch
or
the
bat-
tery
through
the
main
fuse/relay
panel,
located
in
¡he
left
rear
comer
of
the
engine
compartment
.
Fuses
are
color
coded
to
indicate
current
capacities
.
The
relays
and
control
units/modules
are
mounted
in
vari-
ous
places
throughout
the
vehicle
.

Please
read
the
following
warnings
and
cautions
before
do-
ing
any
work
on
your
electrical
system
.
WARNING
-
"
The
cars
covered
by
this
manual
are
equipped
with
aSupplemental
Restraint
System
(SRS)
that
automatically
deploys
one
or
more
airbags
.
Each
airbag
unit
houses
an
explosive
powerful
charge
.
Any
work
involving
the
SRS
system
should
only
be
performed
byan
authorized
BMW
dealer
.
Making
repairs
without
the
proper
knowledge
and
special
test
equipment
may
cause
serious
per-
sonal
injury
.
See
721
Airbag
System
(SRS)
.
"
The
ignition
system
of
the
car
operates
at
lethal
voltages
.
People
with
pacemakers
or
weak
hearts
should
not
expose
themselves
to
the
ignition
sys-
tem
.
Extra
caution
mustbe
taken
when
working
on
the
ignition
system
or
when
servicing
theen-
gine
while
it
is
runningor
the
key
is
on
.
See
120
Ignition
System
for
additional
ignition
system
warnings
and
cautions
.
"
Before
operating
the
starter
without
starting
the
engine
(as
when
making
a
compressfon
test),
dis-
able
the
ignition
system
as
described
in

Electrical
Test
Equipment
Many
of
the
electrical
tests
described
in
this
manual
call
for
measuring
voltage,
currentorresistanceusing
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
display
is
alsoless
likely
to
be
misread,
since
there
is
no

dle
position
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
digital
