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).

Operating principle of dtc
The bbs receives the front and rear speed information from the abs over the
can. Then, the bbs sends the vehicle speed
information to be displayed on the dashboard over the can.
If the tangential speed of the rear wheel exceeds the tangential speed of the
front wheel by a given percentage, t ...
Refuelling
Never overfill the tank when refuelling. The fuel level should
always be below the rim of the filler recess.
Warning
Use low-lead fuel with 95 octane rating at origin
minimum (see "top-ups" table, page 173).
Check that no fuel is trapped in the filler cap recess.
