Troubleshooting And Elimination; The Starter Not Operate, Low Power Output Or Its Fuse Burnout; Generator Not Work Or Low Power Output - Chery QQ6 Service Manual

operating. When the generator itself can generate electric power, the system will switch to the
self-excitation mode. In addition, when the generator is generating electric power, it gives a signal
to the relevant instrument via the D+ terminal. After the instrument receive the signal from the
generator, the battery indicator on the instrument will be extinguished.

3. Troubleshooting and Elimination

3.1. The starter not operate, low power output or its fuse burnout

Not operate: When the key is in starting position, if the sound of action of pull-in winding can be
heard while the motor doesn't operate, this may be caused due to the battery no power output,
contact in pull-in winding failure or starter ground poor.
Low power output: The starter can operate while with low power output. The cause may be low
power output of battery, or high resistance of engine mechanical parts.
Fuse burnout: If the fuse burns out frequently when starting, it may be caused due to the starter
ground poor, wire connection poor or starter interior and engine interior resistance overhigh.

3.2. Generator not work or low power output

Generator not work: Generator's not working may make an influence on many systems, and also
result that the battery is used out rapidly. The cause to result the generator doesn't work may be
the exciting circuit work poor, and also may be the rotor, carbon brush or rectification regulator
inside generator failure. Of course, the generator is now unallowable to be repaired. If the trouble
is caused due to the generator problem, please replace the generator assy..
Power output low or overhigh: When the generator's power output is low, it may result that the
system voltage is low and many systems fail to work normally. For the vehicle equipped with ABS
system, the ABS system is very sensitive to the power output of generator. In case that the power
output is low, the system immediately changes to the failure mode. The main cause to result the
low power output may be the reguator inside the generator work poor or generator's belt loose and
etc. The power output overhigh generally means that the voltage is overhigh, which easily
damages the electical devices. This is a very dangerous failure which may result the electrical
harness catches a fire. The generator voltage overhigh is mainly caused due to the regulating
circuit inside the generator work poor.
