Operating Instructions
2. Excessive
self-discharge
(1) There are impurities in the electrolyte.
(2) There is a short circuit in the external
wires of the battery.
(3) There is electrolyte on the surface of the
battery, causing a short circuit between
the positive and negative poles
(4) There are metal tools or rod pieces
between the positive and negative
terminals, causing a severe short
circuit.
(5) The active material on the plate comes off
and deposits, causing a short circuit
between the plates; there is a short
circuit between the plates due to a
damaged separator; the plates are
deformed, causing a short circuit
between the plates
(1) Replace the battery
(2) Check the shorted part and eliminate the
fault.
(3) Use alkaline water or warm water to wash
the battery surface and terminal so as to
keep the surface clean (prevent the water
from entering the battery)
(4) Remove the metal tools or rod pieces on
the surface of the battery.

Troubleshooting methods
1
The water
temperature
gauge pointer
always points to
low temperature.
(1) The circuit is open, and the connector
is in poor contact.
(2) Water temperature sensor damaged
(3) The water temperature gauge fails.
(1) Repair the circuit and remove the dirt
at the connector.
(2) Replace the coolant temperature
sensor
(3) Replace the instrument
2
The water
temperature
gauge pointer
always points to
high
temperature.
(1) Short circuit damage of water
temperature sensor
(2) There is a short circuit.
(3) The water temperature gauge fails.
(1) Replace the coolant temperature
sensor.
(2) Repair it and eliminate the
short-circuit fault.
(3) Replace the instrument
3
The indication
of oil pressure
gauge is
abnormal.
(1) There are open circuit and short
circuit.
(2) There are open circuit, short circuit
and poor contact in the sensor.
(3) The oil pressure gauge fails.
(1) Check and eliminate the fault.
(2) Repair or replace the sensor.
(3) Replace the instrument
