Faults phenomena and maintenance methods
Faults phenomena: No power supply
①No power of battery:
A. Press the button on the battery indicator to observe if the indicator light is lighted or not, the red light is means lowest power, the
red light flashing is means that the battery has been run out.
B. Use the wire to connect between the positive pole of the battery and the K-⑧ pin of the battery to measure the voltage should be
higher than 50V for positive pole① of the battery and the voltage of the negative pole ② with the multimeter to 200V DC voltage
section, otherwise the battery is out of power, you need to charge the battery, the following is the interface diagram of battery output:
C. If the battery is fully charged, follow and b steps to test, if the battery voltage is still low, you need to repair and replacement
because of the battery is break down.
② battery has power, but no power supply after connected to the vehicle
A. If the battery has power, connected to the vehicle battery plug, open the ignition lock; if the vehicle is no power, you should the
battery plug is reliable connected, re-connect and confirm again.
B. if confirmed the battery is connected with the vehicle, and open the ignition lock, the vehicle is still no power. measure the positive
and negative of charging port whether there is power(voltage same as the battery port);To measure the voltage of positive pole ①
and negative ③ pole whether it is same as the battery port with 200V DC voltage by multimeter after open the ignition lock.
C. If the voltage is too low or no voltage, it means the battery didn’t normal output, to check the fuse on the vehicle of 70A and 5A
whether its fusing (to disconnect the battery first), 5A fuse is below the seat and in the cover of controller, need to open the cover to
check; if the 70A fuse is fusing, need to check whether the controller is burnout, if 5A fuse is fusing, then need to check whether the
DC converter is burnout.
⑴Method of measuring controller
Make sure that the battery is disconnected from the battery plug, open the cover of line ball of the controller, adjust the multimeter to
buzzer, and check whether the positive and negative terminals of the controller is conduction state (interchange red and black probe
to test) ,If conduction state, the controller is burnout, if not, need to check whether it is conduction state between the positive or
negative pole of the controller and the motor phase line(interchange red and black probe to test), the controller is burnout and need
to replace if conduction state.
⑵ Method of measuring the DC converter
As with the method of measuring controller, remove the vehicle headlamp parts and converter plug, measure the converter red line
and green line or black line if its turned on, if conducted, it means that the converter has burned, they need to be replaced.
D. When the fault is identified, after confirmed unnecessary fault or replacement, turn on the battery and open ignition lock again to
confirm if the vehicle is normal, test the voltage of vehicle charging port whether its normal or not.
E. If the fuse is not blown, Check,whether the ignition lock is burned, remove the vehicle headlamp parts, unplug the ignition lock
