Ducati Diavel Service Manual: Checking the battery charging system
To check the current flow of the recharging circuit, use the "dds" diagnosis instrument, which is equipped with an inductive clamp-type amperemeter: refer to chapter "testing the battery charging system", sect. 6 - 11 With the dds diagnosis instrument you can determine the engine rpm required for the alternator to produce sufficient current to charge the battery, feed the injection/ignition system and all the electrical equipment on the motorcycle. When applied to a cable, the clamp-type amperemeter detects the magnetic field generated by the current passing through that cable.
The tester performs an automatic calibration routine using its own transducer. If the measured current is a positive quantity, it means that generator is feeding all electric items and charging battery at the same time. A negative value means that charging system is not powering the loads and a significant amount of current must be supplied by the battery, which is discharging at the time of the measurement.
Or it is possible to use a multimeter (sect. 6 -11, Diagnostic instruments); connect the multimeter probes to the battery terminals, select the dc scale on the instrument and check for the presence of 14.5 V+/-0.5 At an engine speed of 3000 rpm.
Important
If polarity is reversed when clamping the ammeter onto the cable, the sign of the readings will also be reversed, giving rise to incorrect diagnosis.
Recharging the battery
Examine the label on the battery showing the check intervals in order to
determine when to test the voltage.
Charge the battery if the open circuit voltage is lower than 12.8 V. Leaving

Refitting the alternator-side crankcase cover
Before the assembly make sure that the water pump unit is fitted on the
generator cover (sect. 9 - 3.3, Refitting the
water pump).
If bearing (27) has been removed, lubricate its seat with specified grease to
fit it on the generator cover (13).
Fit bearing completely in its seat and orien ...
Recovery procedure with no key
When the dashboard is on and the key has been recognised, the hands free
attempts to detect the key every 60 seconds.
If the engine is off and the on/off switch on the handlebar is turned to "run
off", if no key is detected within 10 seconds,
the dashboard switches off automatically.
If t ...
Pre-ride checks
Warning
failure to carry out these checks before riding, may
lead to motorcycle damage and injury to rider and passenger.
Before riding, perform a thorough check-up on your bike as
follows:
Fuel level in the tank
Check the fuel level in the tank. Fill tank if needed (page 140).
