Electrical system
Diagnostic code - 3 flashes
The 3-flash code indicates a system where the de-
coder does not recognise the key. Turn the switch
to ON using several keys: If the error code is re-
peated even with the Master key, replace the de-
coder. If this is not the case, reprogram the
decoder.
Battery recharge circuit
The recharge system is provided with a three phase alternator with permanent flywheel.
The alternator 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.
This system therefore requires no connection to the key switch.
The three- phase generator provides good recharge power and at low revs, a good compromise is
achieved between generated power and idle stability.
Stator check
Stator winding check-up
WARNING
THIS CHECK-UP CAN BE MADE WITH THE STATOR PROPERLY INSTALLED.
1) Remove the central chassis cover.
2) Disconnect the connectors between stator and regulator with the three yellow cables.
3) Measure the resistance between each of the yellow terminals and the other two.
