1) Remove the door in the saddle compartment.
2) Disconnect the connector between the stator and regulator with the three yellow wires.
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) Check that the battery does not show signs of leaking fluid before checking the output voltage.
2) Turn the ignition key to OFF and connect the multimeter leads between the battery negative pole (-)
and the Black cable.
3) With the multimeter leads connected, disconnect the Black cable from the battery negative pole (-).
4) With the ignition key always at OFF, the reading indicated by the ammeter must be ≤ 0.5 mA.
Maximum current output check.
- With engine off and panel set to "ON" turn on the lights and let the battery voltage set to 12V.
- Connect ammeter pliers to the 2 recharge positive poles in output from the regulator.
- Keep the lights on and start the engine, bring it to normal speed and read the values on the ammeter.
With an efficient battery a value must be detected: > 20A
Check the charging current
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 tester terminals between the battery
terminals..
3) Start the engine, ensure that the lights are all out, increase the engine speed and at the same time
measure the voltage.
