2. Inspect lighting equipment, etc.
1) First inspect the lights, horn, wiper and other electrical components to find out whether
they are fault-free or not;
2) If there is any error, then inspect the corresponding fuse to find out whether there is
any error according to the schematic, if there is any error, replace it;
3) If the relevant fuse has no error, then inspect the electric cable of each electric parts
with the entire vehicle charged with electricity, to inspect whether there is 24V voltage,
if no voltage, then inspect the power cable between electrical parts and the fuse is
broken or not;
4) If the voltage is measured, please replace the relevant electric parts.
3. Inspection of Instrument and equipment
1) After the machine is powered on, inspect whether instrument indications are normal;
2) In case of any failure, first inspect whether the sensors are damaged or not; in case of
no damage, inspect the corresponding temperatures in the following table to confirm
whether the resistances meet the requirements in the table below.

3) If the sensor is fault-free, then inspect the cable from each sensor to the front of the
instrument, to inspect whether it is normal without damage or not.
