WORK
This is the system device that requires the most assiduo-
us surveillance and the most diligent maintenance.
If the vehicle is not used for a certain period (1 mon-
th and more), the battery needs periodical recharging.
The battery tends to go completely flat within around
3 months. When reinstalling the battery on the motor
cycle, be careful not to invert connections, considering
that the black earth wire must be connected to the ne-
gative terminal, whereas the other red wire must be
connected to the terminal marked with + sign.
