Chery QQ Service Manual Charging System
Note:
Take into consideration that the voltage varies with the temperature of the regulator ※
case.
Before this test, the discharged batte※ ry must be fully charged.
Note: When the engine runs, never remove the terminal post of the battery, otherwise,
the electronic parts may be damaged.
Standard current: 10A (max.)
Standard voltage: 14.2-14.8V in 25°C
Higher voltage
If the voltage is higher than the standard value, replace the regulator of integrated
circuit.
Lower voltage
If the voltage is lower than the standard value, conduct the following check. Connect
the F terminal post to the ground connection, start the engine, and then measure the
voltage of B terminal post.
If the voltage goes up above the standard value, there is something wrong with the
engine.
Loading check
Make the engine run at a rotation speed of 2000r/min, and switch on the head lights
and the fan of heater system. And then measure the current. If the current is lower
