Table 3-12 Battery failure and troubleshooting
Failure Cause Troubleshooting
T
he battery
power is
insufficient and
difficult to start
engine.
(1) The electrolyte is too low.
(2)
The circuit between pole plates is
short-cut.
(3) Vulcanization of pole plate occurs.
(4)
The terminal is not well connected.
There is too much oxidate on the pole.
Charging power is insufficient.
(1) Replace battery
(2)
Clean the deposition and replace
electrolyte.
(3)
Clean the vulcanization by repeatedly
charging and discharging the battery.
(4)
Tighten the connection. Clean the
oxidate to coat a
thin layer of Vaseline
on the pole.
2. Discharging
current is too
high.
(1) There is foreign material in electrolyte
(2) There is short circuit outside of battery.
(3)
Electrolyte is spilled out of battery,
causing shortcut of positive and
negative poles.
(4)
Place the metal tool or lever between
the positive pole and negative pole,
causing severe shortcut.
(5) The active material is off of pole plate
or the active material deposits too
much, causing the shortcut of pole plate.
The insulator is dama
ged, causing
shortcut of pole plate. The pole plate is
warped, causing battery shortcut.
(1) Replace battery
(2) Find out the shortcut circuit to solve the
problem.
(3)
Wipe the battery surface and poles with
alkaline water or warm water to keep it
clean (do not let the water enter battery)
(4)
Do not lay the metal rod or tools on the
surface of battery.
3.16.2.4 Instrument failure and troubleshooting
Table 3-13 Instrument failure and troubleshooting
Index: Failure Cause Troubleshooting
1
Water
temperature
gauge pointer
always points to
low temperature
zone.
(1)
Circuit is open. Connector is not
well connected.
(2)
Water temperature sensor is
damaged.
(3) Water temperature gauge is fault.
(1) Repair the circuit and clean the dirt
at the connector.
(2) Replace water temperature sensor.
(3) Replace instrument.
2
Water
temperature
gauge pointer
always points to
high temperature
zone.
(1)
Water temperature sensor is
damaged by shortcut.
(2) There is shortcut in all circuits.
(3) Water temperature gauge is fault.
(1) Replace water temperature sensor.
(2) Check and solve failure of short-cut
circuit.
(3) Replace instrument.
3
Oil pressure
gauge could not
indicate
normally.
(1) There is shortcut or open in circuit.
(2) Sensor circuit is open, shortcut or not
well connected.
(3) Oil pressure gauge is fault.
(1) Troubleshoot it.
(2) Repair of replace sensor.
(3) Replace instrument.
4
Barometer
could not
indicate
normally.
(1) Instrument is damaged.
(2) Air is leaking out of pipe.
(1) Repair of replace instrument.
(2) Repair of replace air pipe.
