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).

Reassembly of the gearbox
To refit the gearbox components follow the procedure under sect. 9 - 9.2,
Reassembly of the crankcase halves, relating to
reassembly of the engine crankcase.
As a final practical test, ensure that with the gearbox in neutral the front
coupling dogs (a) of sliding gears (b) are

Headlight control
This function allows you to reduce current consumption from
the battery, by automatically managing headlight switchingoff.
At key-on, the high beam and low beam lights are off.
When the engine is started, the low beam lights turn on

Replacing the battery in the active key
Only use 3 volt cr 2032 lithium ion batteries.
Note
The keys do not need to be reprogrammed after
replacing the battery.
Remove the metal part of the battery.
Use a large sized coin to pry open the shells of the plastic grip
(2? coin) as shown in fig. 65.
