Removing The Generator - Ducati MULTISTRADA 1200S ABS 2015 Workshop Manual

Alternator / Generator
The generator used on the Multistrada 1200 has a rated power of 490W at 14V and consists of a fixed element
(stator/generator, A), located in the generator cover and a mobile element (rotor/flywheel, B) fastened to the
crankshaft.
Rotor (B) is manufactured with strong permanent magnets and features a lot of pin pairs for each stator phase.
This allows generating alternate voltage at a higher frequency compared to a standard generator. The result: at
low rpm it is possible to generate higher current.
Important
Check the charging current by using the "DDS" diagnosis instrument.
To check the generator, measure the voltage at each end of the generator cable and check if it is compliant with
the value indicated in the table (ambient temperature: 20 °C).
Attention
Before testing, disconnect the generator wiring from the electrical system when the ignition key is set to OFF.
Rpm Active voltage
1500 rpm 27.5 V
2500 rpm 45 V
Values significantly lower than those indicated above can be due to:
- partially demagnetised rotor;
- short-circuited windings.
In the above cases the whole generator assembly (rotor and stator) should be replaced.
If checks have a favourable outcome, reconnect the generator to the regulator with ignition key on OFF. Make sure
that no cables are damaged or disconnected.
