ELECTRIC WIRING
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.
Do not reverse the positive (+) and negative (-) ends of the
battery cable. The alternator diode and stator coil will be
damaged.
When the battery indicator goes out, it should not come on
again. The battery indicator only comes on during operation
if the alternator fails or if the V-belt breaks. However, if an
LED is used in the battery indicator, the LED will shine
faintly during normal operation.
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.
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.
