ELECTRICAL SYSTEM
Spark plug
Check electrode gap "A" (0,6 mm) (0,02 in.). A wider gap may cause difficulties
in starting the engine and overload the coil. A gap that is too narrow may cause
difficulties when accelerating, when idling or poor performance at low speed.
Clean off any dirt around spark plug base before removing the spark plug. It is
good practice to closely inspect the spark plug after removal, as any deposits
on it and the colour of the insulator provide useful indications on spark plug
heat rating, carburetion, ignition and the general condition of the engine. Before
refitting the spark plug, accurately clean the insulator with a wire brush. Smear
some graphite grease on spark plug thread, do it fully home finger tight then
tighten it to 13 Nm - 1,3 Kgm - 9,59 ft/lb. Loosen the spark plug then tighten it
again to 13 Nm - 1,3 Kgm - 9,59 ft/lb. Spark plugs which have cracked insulators
or corroded electrodes should be replaced.
Battery
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 (0.5A for
8 hours for 12V-10Ah battery).
Quick charging is advised only in situations of extreme necessity since the life
of lead elements is drastically reduced by such cycle (5A for 0.5 hours for 12V-
10Ah battery).
Battery charger
To gain access to the battery (1):
- remove the elastic band;
- first remove the BLACK negative cable, then the RED positive cable (when reas -
sembling, first connect the RED positive cable, then the BLACK negative cable);
- remove the battery (1) from its housing.
Use a voltmeter to ensure that the battery voltage is not lower than 12.5V. 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.
