TROUBLESHOOTING

TroubleshootIng
the
Datsun
can
be

relatlvely

simple
1f
done

lOgically
The
first

step
must

always
be
to
define

symptoms
as

closely
as

pos

Sible

Subsequent
steps
mvolve

testIng
and
an

alyzmg
areas
which
could
cause
the

symptoms

Procedures

typical
symp

methods
of

These
are
not
the

only
methods
There

may
be

several

approaches
to

solvmg
a

problem
but
all

Voltmeter
Ammeter
and
Ohmmeter

For

testIng
the

ignitlon

electncal

systems

a

good
voltmeter
is

reqUIred
For
automotIve

use
an
mstrument

factory
It
should
have
an

accuracy
of
about

Ih

volt
which
excludes
the
common
auto

moUve

type
found
in
instrument

An
ohmmeter
measures
electncal
reSiStance

and

is

reqUired
to
check
electncal

contInUity

open
and

short
circwts
and
for

testing
fuses

and

hghts

The
ammeter
measures
electncal
current
One

for
automotIve
use
should
cover
0
10
and
0
100

amperes
An
ammeter
is
useful
for

checkmg
bat

tery
chargmg
and

startIng
current
The

Hydrometer

A

hydrometer
is

necessary
to
check

battery

It
will
be
eVident

by

always
detenIlIDe
what

correct
the

trouble

Never

replace

a
