ELECTRICAL SYSTEM
BATTERY (TE - TXC)
The battery (1) is a sealed-for-life, maintenance-free battery. If the vehicle
remains unused for long periods, it is recommended to disconnect the battery
from the electrical system and store it in a dry place. After an intensive use of
the battery, it is advisable to carry out a standard slow charging cycle (12V-6Ah
battery: 0.6A for 8 hours).
Quick charging is advised only in situations of extreme necessity since the life
of lead elements is drastically reduced by such cycle (12V-6Ah battery: 6A for
0.5 hours).
Battery charger
To gain access to the battery (1):
- remove the saddle (as outlined in the relevant paragraph);
- first remove the BLACK negative cable, then the RED positive cable (when
reassembling, first connect the RED positive cable, then the BLACK negative
cable);
- remove the battery (1) from its housing.
Check, using a voltmeter, that battery voltage is not less than 12.5 V. If it is not
so, the battery needs to be charged. Using a battery charger with a constant
voltage, first connect the RED positive cable to the battery positive terminal then
the BLACK negative cable to the battery negative terminal. At a constant voltage
level of 14.4 V, apply “x” Amps according the battery's charge percentage as
indicated in the table below. The voltage reaches a constant value only after a
few hours, therefore it is suggested NOT to measure it immediately after hav-
ing charged or discharged the battery. Always check the battery charge before
reinstalling it on the vehicle. The battery should be kept clean and the terminals
coated with grease.
