Electrical system
Replace the control unit if there is no voltage; oth-
erwise, check the wiring connections between the
starter and the control unit.
Turn signals system check
- If the turn indicators do not work, proceed as fol-
lows:
- Disconnect the electronic control unit connector
and check that there is voltage between terminal
9 (Orange) and the earth connection with the key
switch set to "ON".
- Check that the same happens between terminal
9 (Orange) and terminal 12 (Black).
If no voltage is detected, check the cable harness
and the connections; otherwise, proceed as fol-
lows:
- Jump terminals 2 (Black/Blue) and 9 (Orange),
see figure. Turn the turn indicator switch alternate-
ly to the left and to the right with the key switch in
"ON" and check if the lights turn on.
If they do, replace the control unit because it is
faulty.
If they do not turn on, check the control unit-turn
indicator switch connection cable harness; then,
repeat the test.
Sealed battery
If the vehicle is provided with a sealed battery, the only maintenance required is the check of its charge
and recharging, if necessary.
These operations should be carried out before delivering the vehicle, and on a six-month basis while
the vehicle is stored in open circuit.
Besides, upon pre-delivery it is therefore necessary to check the battery charge and recharge it, if
required, before storing the vehicle and, afterwards, every six months.
INSTRUCTIONS FOR THE RENEWAL RECHARGE AFTER OPEN-CIRCUIT STORAGE
1) Voltage check up
Before installing the battery on the vehicle, check the open circuit voltage with a regular tester.
- If voltage exceeds 12.60 V, the battery can be installed without any renewal recharge.
- If voltage is below 12.60 V, a renewal recharge is required as explained in 2).
