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 windings
WARNING
THIS CHECK-UP CAN BE MADE WITH THE STATOR PROPERLY INSTALLED.
1) Lift the saddle and remove the helmet compartment.
2) Disconnect the connector between stator and regulator with the three yellow cables as shown in the
picture.
3) Measure the resistance between each of the yellow terminals and the other two.
Electric characteristic
Resistance:
0.2 - 1
Ω
4) Check that there is insulation between the each
yellow cable and the ground.
5) If values are incorrect, replace the stator.
Recharge system voltage check
Look for any leakage
1) Access the battery by removing the cover in the footrest.
2) Check that the battery does not show signs of losing fluid before checking the output voltage.
3) Turn the ignition key to position OFF, connect the terminals of the tester between the negative pole
(-) of the battery and the black cable and only then disconnect the black cable from the negative pole
(-) of the battery.
4) With the ignition key always at OFF, the reading indicated by the ammeter must be
≤
0.5 mA.
Charging current check
WARNING
BEFORE CARRYING OUT THE CHECK, MAKE SURE THAT THE BATTERY IS IN GOOD WORK-
ING ORDER.
1) Place the vehicle on its centre stand
2) With the battery correctly connected to the circuit, place the multimeter leads between the battery
terminals..
