GI CAUTKN
PRECAUTIONS TO TAKE WHEN SERVICING AN ELECTRICAL SYSTEM l Note the following items when servicing the electrical system.
l Do not alter the wiring or electrical equipment in any way; this may damage the vehicle or cause a fire
from short-circuiting a circuit or overloading it.
l The negatrve (-) battery cable must be removed first and
rnstalled last. l Do not reptace with fuses exceedrng specified capacity
Cautron
l 8e sure that the ignitton and other switches are off
before disconnectrng or connecting the battery cables.
Failure to do so may damage the semrconductor
components. Caution l Repfacing a fuse with one of a larger capacrty than
desrgnated may damage components or cause a frre.
l Secure harnesses with provrded clamps to take up slack. l Tape areas of the harness
that may rub or bump l When mounting
components, be sure the
against sharp edges to
protect rt from damage. harness IS not caught or
damaged.
Caution
l Clamp all harnesses near vibratrng components (for
example, the engine) to remove slack and to prevent
contact resultrng from vibration. i Drsconnect heatsensitive l Make sure that the
parts (for example, relays
and ECU) when performing connectors are securely
connected when installed.
l Do not handle electrical components roughly or drop
them. maintenance (such as
weldrng) where
temperatures may exceed
80°C [176OFj.

GI CAUTION
USING ELECTRICAL MEASURING EQUIPMENT
Use Handling precautions Operation Equpment
Test lamp Test to find open or shorted
crrcuits
l Connect the test lamp
between the circuit being
measured and a ground.
l The lamp will lrght if the
circurt is energized to the
point testedA
l Test lamps use 12V t.4W or
3.4W bulbs or light-emitting
diodes (LEOs). Using a
large-capacity bulb may
damage :he Ckil.
Jumper wrre Used to create a temporary
ctrcult . Connect the jumper wire
between the terminals of a
cjrcurt to bypass a switch. l 00 not connect the lumper
wrre from the power source
line to ground; this may
cause burning or other
damage to harnesses or
electrontc components.
Voltmeter Used for measuring the voltage
of a circutt to find possible
opens or shot-k.
l Connect the voltmeter in
parallel wrth the cjrcurt.
l Set the range to the dewed
voltage.
l Use the service hole when measuring the voltage at the
diagnosis connector.
l Connect the positive (+)
probe to the point where
voltage IS to be. measured
and the negatrve (-) probe to
a ground.
l Tie a thin wire to the
posrtive (+) probe to access
narrow terminals.
Ohmmeter Used to find opens and shorts
In the ctrcurt, to confrrm
contrnurty and to measure
reststance.
l Zero the ohmmeter. l Zero the meter after
switching to the measuring
range.
l Before using the ohmmeter,
make sure the ignitron
switch is off or the megatrve
(-) battery cable is
disconnected to prevent
burning or otherwise
damaging the ohmmeter. &--- l Verify that voltage IS not
applied to the circuit
l Connect the probes between
two points in a Circuit.,
t I t
+ Connect the ammeter in
series with the circuit by
touchtng the positive ( +)
probe to the power-srde
terminal and the negative (-
probe to the ground-srde
terminal. Ammeter
Used to check alternator output,
current supplied to the starter.
and dark current wrthrn a circutt. l Set the range to the desired
amperage.
l Connect the ammeter In
series with the circuit. The
ammeter may be burned or
otherwise damaged if it IS
connected in parallel. Note
Dark current IS the constant flow
of current whrle
the ignitron
switch is OFF.
