Diagnostic code - 3 flashes
Il codice 3 lampi contraddistingue un impianto
dove la centralina non riconosce la chiave (ovvero
riconoscimento del transponder, ma non inserito
in programmazione, una chiave è rimasta fuori
dalla programmazione). Procedere con una nuova
programmazione, passando tutte le chiavi . Com-
mutare l'interruttore in ON utilizzando più chiavi:
se il codice di errore viene ripetuto anche con la
chiave Master, la centralina risulta difettosa.
Remote controls check
To check the operation of a relay:
1) Check that, given regular conditions, there is no
continuity between terminals 87 and 30.
2) Apply a 12V voltage to power terminals 86 and
85 of the relay.
3) With the relay fed, check that there is continuity
between terminals 87 and 30.
4) If these conditions are not met, the relay is sure-
ly damaged and, therefore, it should be replaced.
Battery recharge circuit
The charging circuit consists of three-phase alternator and a permanent magneto flywheel.
The generator is directly connected to the voltage regulator.
This, in its turn, is connected directly to the ground and the battery positive terminal passing through
the 30A protective fuse.
The three-phase alternator provides good recharge power and at low revs a good compromise is ach-
ieved between generated power and idle stability.
Stator check
Checking the stator winding
WARNING
THE CHECK-UP CAN BE MADE WITH THE STATOR PROPERLY INSTALLED.
1) Remove the right side panel.
2) Disconnect the connector between stator and regulator with the three yellow cables as shown in the
picture.
