Electric Wiring - Yanmar 3TNV82A-B Service Manual

SAFETY
CAUTION
Make sure that the combined total
resistance of the battery cable in both
directions between the starter motor
and the battery is within the value
indicated on the wiring diagram. The
starter motor will malfunction or break
down if the resistance is higher than the
specified value.
CAUTION
The starter motor is water-proofed
according to JIS D 0203, R2 which
protects the motor from rain or general
cleaning. Do not use high-pressure
wash or submerse the starter motor in
water.
CAUTION
Use a specialized battery charger to
recharge a battery with a voltage of
8 volts or less. Booster starting a battery
with a voltage of 8 volts or less will
generate an abnormally high voltage
and destroy electrical equipment.
CAUTION
Make sure that the combined total
resistance of the battery cable in both
directions between the starter motor
and the battery is within the value
indicated in the Battery Cable
Resistance chart in the Electric Wiring
Section of this manual. The starter
motor will malfunction and fail if the
resistance is higher than the specified
value.
3-20
Removing the battery cables or the
battery while the engine is operating
may cause damage to the current limiter
depending on the electrical equipment
being used. This situation could cause
loss of control of output voltage. The
continuous high voltage of 23-24 volts
(for 5000 rpm dynamo) will damage the
current limiter and other electrical
0000054en
equipment.
Reversing the battery cable connections
at the battery or on the engine will
destroy the SCR diode in the current
limiter. This will cause the charging
system to malfunction and may cause
0000055en
damage to the electrical harnesses.
Avoid damage to the turbocharger or the
engine. Do not spray blower wash fluid
or water too quickly.
Use short strokes from a spray bottle to
inject blower wash fluid or water into the
0000056en
turbocharger.
Spraying too much wash fluid or water,
or spraying too quickly will damage the
turbocharger.
Do not allow any material to fall into the
oil lines or the oil inlet and outlet ports
of the turbocharger.
