Table 2-10 Battery Faults and Troubleshooting
Fault
Causes
Troubleshooting
The battery capacity is
low and the engine is
hard to start
(1) Short circuit between electrode plates in
the battery
(2) Sulphurization of the electrode plates in
the battery
(3) Poor circuit connector contact, or too
much oxidation
(1) Replace battery
(2) Replace battery
(3) Clean battery terminal, securely
fasten cable connector, and coat with
a layer of petroleum jelly
Excessive battery
discharging
(1) Impurities in the electrolytes
(2) Short circuits exist in the
electrical system
(3) Short circuit caused by placement of
a metal tool or bar between
positive/negative posts.
(4) Corrosion on battery terminals or cables
(1) Replace battery
(2) Troubleshoot and repair
(3) Remove metal object, replace
battery if necessary
(4) Clean and replace if necessary

Fault
Causes
Solutions
The water temperature
gauge always indicates a
low temperature
(1) Break in the circuit or the plug is
making poor contact
(2) The water temperature sensor
is damaged
(3) The water temperature gauge is broken
(1) Overhaul the circuit, or remove the
dirt at the plug
(2) Replace the water
temperature sensor
(3) Replace the gauge
The water temperature
gauge always indicates a
high temperature
(1) The water temperature sensor
is damaged
(2) There is a broken circuit or a
short circuit
(3) The water temperature gauge is broken
(1) Replace the water
temperature sensor
(2) Check and repair-circuit faults
(3) Replace the gauge
The oil pressure gauge
is abnormal
(1) The oil pressure sensor is damaged
(2) There is broken circuit or a short circuit
(3) The oil pressure gauge is bad
(1) Replace the oil pressure sensor
(2) Check and repair circuit faults
(3) Replace the gauge
