Ducati Diavel Service Manual: Alternator
It is equipped with a 12 v, 430 w generator, consisting of a fixed element (stator, a) located on the generator cover and of a movable element (rotor, b) fixed to the crankshaft.
Note
To check the battery charging system for faults, use the dds diagnosis instrument and follow the instructions given in the paragraph, "testing the battery charging system" (sect. 6 - 11).
The absolute value of voltage measured across the terminals of two of the three yellow cables (the measured value will be the same whichever combination of cable is used) must be within the range indicated in the table below.
(Ambient temperature: 35 C - 70 C)
Important
Before testing, disconnect the alternator wiring from the electrical system when the ignition key is set to off.
Values significantly lower than those indicated above can be due to:
- Partially demagnetised rotor;
- Short-circuited windings.
In the above cases the whole alternator assembly (rotor and stator) should be renewed.
If checks have a favourable outcome, reconnect the alternator to the regulator with ignition key on off. Make sure that no cables are damaged or disconnected.
Removal of the alternator
Disconnect the cables of the alternator-side electric system (sect. 6 -1, Routing of wiring on frame).
Remove the generator cover, the stator (a) and the rotor (b) (sect. 9 - 8, Removal of the generator cover).
Refitting the
Refitting the generator
Fit the rotor (b), the stator (a) and the alternator-side crankcase cover.
Connect the cables of the generator side electric system (refer to the table in chapter "routing of wiring on frame", sect. 6 - 1).

Riding mode set indication
This function indicates the "riding style" set for the vehicle.
Three "riding modes" are available: sport, touring and urban.
Each riding mode can be changed using the "riding mode" function.

Trip 1 meter
This function shows the distance travelled since the trip meter was last
reset (in km or miles depending on the specific
application).
Press and hold (1) "s" for 3 seconds while in this function to reset the trip
odometer.
When the reading exceeds 9999.9, Distance travelled is reset and t ...
Adjusting the chain tension
Make the rear wheel turn until you find the position where chain is tightest.
Set the vehicle on the side stand. Push down
the chain at the point of measurement and release. Measure the distance between
the "aperture" upper profile and pin
centre.
The read distance must be: 9 to 11 mm.
