The

a
six-cell,
12-volt
leadacid
battery
mounted
in
the
luggage
compartment
.

NOTE-
E36
convertible
models
require
a
specialbattery
which
is
designed
for
constant
vibratfon
.
A
battery
not
de-signed
for
this
will
fail
much
earlier
.
Battery
capacity
is
determined
by
the
amount
of
current
needed
tostart
the
vehicle,
and
by
the
amount
of
current
con-
sumed
by
the
electrical
system
.
BMW
batteries
are
rated
by
ampere/hours
(Ah)
and
cold
cranking
amps
(CCA)
rating
.
The
Ah
rating
is
determined
by
the
average
amount
of
current
the
battery
can
deliver
over
time
without
dropping
below
a
specified
voltage
.
The
CCA
is
determined
by
the
battery's
ability
to
deliver
starting
current
at
0°
F
(-18°
C)
without
dropping
below
a
specified
voltage
.

Battery
testing
determines
the
state
of
battery
charge
.
On
conventional
or
low-maintenance
batteries
the
most
common
method
of
testing
the
battery
is
that
of
checking
the
specific
gravity
of
the
electrolyte
using
a
hydrometer
.
Before
testing
the
battery,
check
that
the
cables
are
tight
and
free
of
corro-
sion
.
See
Fig
.

.
Hydrometer
Testing
The
hydrometer
consists
of
a
glass
cylinder
with
a
freely
moving
float
inside
.
When

is
drawn
into
the
cylin-
der,

Before
checking
the

of
a

load
the

.
lf
the

A
brief
description
of
the
principal
parts
of
the
electrical
sys-

presented
here
.
Also
covered
here
are
basic

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

rear
comer
of
the

.
Fuses
are
color

ous
places
throughout

The
cars
covered
by
this
manual
are
equipped
with
aSupplemental
Restraint
System
(SRS)
that
automatically
deploys

Any
work
involving

system
should
only
be
performed
byan
authorized
BMW
dealer
.
Making
repairs
without
the
proper
knowledge
and
special
test
equipment
may
cause
serious
per-

ELECTRICAL
SYSTEM-GENERAL
Voltage
and
Voltage
Drops
The
wires,
connectors,
and
switches
that
carry
current
are
designed
with
very
low
resistance
so
that
current
flows
with
a
minimum
loss
of
voltage
.
A
voltage
drop
is
caused
by
higher
than
normal
resistance
in
a
circuit
.
This
additional
resistance
actually
decreases
or
stops
the
flow
of
current
.
A
voltage
drop
can
be
noticed
byproblems
ranging
fromdim
headlights
to
sluggish
wipers
.
Some
common
sources
of
voltage
drops
are
corroded
or
dirty
switches,
dirty
or
corroded
connections
or
contacts,
and
loose
or
corroded
ground
wires
and
ground
con-
nections
.
A
voltage
drop
test
is
a
good
test
to
make
if
current
is
flowing
through
the
circuit,
butthe
circuit
is
not
operating
correctly
.
A
voltage
drop
test
will
help
to
pinpoint
a
corroded
ground
strap
or
a
faulty
switch
.
Normally,
there
should
be
less
than
1
volt
drop
across
most
wires
or
closed
switches
.

across
