1.1.3-3 1.1.3-3 Circuit Fault Diagnosis
1 When testing the voltage with test lamp
or voltmeter, connect the negative of
testing tools to battery negative.
2 Connect the other wiring harness of the
test lamp or the positive probe of the
voltmeter to the test position.
3 If a voltmeter is used and voltage display
lower 1 V above compared to the rated
value, it means a circuit fault. It means a
circuit fault if a test lamp is used and lamp
is not lit.
2. Power Testing
1 Disconnect the negative battery cable.
2 Connect one wiring harness of the self-
powered test lamp or the probe of the
ohmmeter to the test component. If using
ohmmeter, please connect the two
probes each other and use reset button
to adjust the ohmmeter to zero.
3 Connect the other wiring harness of the
test lamp or probe of the ohmmeter to the
other side of the test load.
4 If the bulb is lit, it means the circuit is
normal. If an ohmmeter is used and the
resistance value is very low or close to 0
Ω , it means the component has good
continuity.
3. Short Circuit Testing
1 Disconnect negative battery cable.
2 Connect one wiring harness of the self-
powered test lamp or one probe of the
ohmmeter to the output terminal of the
fuse.
3 Connect the other wiring harness of the
test lamp or other probe of the ohmmeter
to the grounding.
4 Disconnect all the electrical loads to the
fuse.
CAUTION: If not disconnecting all the
electrical loads to the fuse, when testing
the low resistance circuit like lights, the
ohmmeter will always display the low
value. This will cause wrong judgement.
5 Do the careful inspection from the place
closest to the fuse.
6 If the bulb is lit or ohmmeter has value
display less than 5
Ω , it means the short
circuit to the ground.
