Power Testing; Short Circuit Testing - Changan M201 2014 Wiring Diagram

1.1.3-3
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.

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
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.

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.
