ELECTRIC WIRING
PRECAUTIONS
Failure to follow these precautions may result in the
failure of an electrical component and the loss of
warranty coverage on that item as well as related
items. Make sure that all users read and
understand these precautions.
CAUTION
Do not reverse the positive (+) and
negative (-) ends of the battery cable.
The alternator diode and stator coil will
be damaged.

CAUTION
When the battery indicator goes out, it
should not come on again. The battery
indicator only comes on during
operation if the alternator fails. However,
if an LED is used in the battery indicator,
the LED will shine faintly during normal
operation.

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.

CAUTION
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
equipment.
0000058en
CAUTION
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
damage to the electrical harnesses.
