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).

Adjusting the throttle cable
The throttle grip in all steering positions must have free play, measured on
the periphery of the flange of the grip, of 1.5 -
2.0 Mm.
If necessary, adjust using the adjusters (1) and (2) located on the steering
tube on the right side of the motorcycle.

Indicating devices
Checking the indicating devices
In the event of a fault, the internal connections of the device must be
checked in all operating conditions. To do this, it is
necessary to disconnect the switch connector from the main wiring harness (sect.
6 - 1, Routing of wiring on frame).
Then analyse th ...
Operating principle and characteristics of the ride-by-wire system
The engine control system of the diavel uses a ride-by-wire system with
motorised throttle valves. This eliminates all
direct connection with metal cables between the throttle grip and the throttle
valves themselves. Cables are used to
rotate the aps potentiometer, which generates an electric ...
