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
120
Igni-
tion
System
.
"
Keep
hands,
clothing
and
other
objects
clear
of
the
electric
radiator
coollng
fan
when
working
on
a
warm
engine
.
The
fan
may
start
at
any
tíme,
even
when
the
ignition
is
switched
off
.

and

in

places
throughout

.
Most

are

(infinite

orfor

circuit
.
Electric
current
is
logical
in
its
flow,
always
moving
from
the
voltage
sourcetoward
ground
.
Electricalfaults
can
usually
be
located
through
a
process
of
elimination
.
When
troubleshoot-
ing
a
complex
circuit,
separate
the
circuit
into
smaller
parts
.
The
general
testsoutlined
below
may
be
helpful
in
finding
electrical
problems
.
The
information
is
most
helpful
when
used
with
the
wiring
diagrams
.
Be
sure
to
analyze
the
problem
.
Use
the
wiring
diagrams
to
determine
the
most
likely
cause
.
Getan
understanding
of
how
the
circuit
works
by
following
the
circuit
from
groundback
to
the
power
source
.
When
making
test
connections
at
connectors
andcompo-
nents,
use
care
to
avoidspreading
or
damaging
the
connec-
tors
or
terminals
.
Some
tests
may
require
jumper
wires
to
bypass
components
or
connections
in
the
wiring
harness
.
When
connecting
jumper
wires,
use
bladeconnectors
at
the
wire
ends
that
match
the
size
of
the
terminal
being
tested
.
The
small
interna¡
contacts
are
easily
spread
apart,
and
this
can
cause
intermittent
or
faultyconnections
that
can
leadto
more
problems
.
