Note
The on-screen icons used during this procedure are explained in a table at the end of this section.
You can determine the engine rpm required for generator to produce just enough current to charge battery, feed the injection ignition system and all electric items fitted to motorcycle. When applied to a cable, the clamp-type amperemeter (1) part no. 88765.1126V detects the magnetic field generated by the current passing through that cable.


Turn on the dds diagnosis instrument (2) referring to the paragraph "tester power supply".
Connect the power and diagnosis cable (measurement module) (3) part no. 97900.0222 To the measurement module connector (d) of the dds (2).

Connect the clamp-type amperemeter (1) to the connector (e) of the power and diagnosis cable (measurement module) (3).

Warning
The clamp-type amperemeter must not be connected to wires through which electrical current is flowing.
Insert the clamp-type amperemeter into the battery positive terminal lead with the arrow on the clamp pointing towards the battery positive terminal (+).
On the dds diagnosis instrument (2), select the "measurement module" function by pressing the corresponding icon; then press the "ammeter" icon (f) followed by the "start" icon.


The socket to which the cable (measurement module) (3) is to be connected is indicated on the screen with a capital letter: a, b or c.


If the measured current is a positive quantity, it means that generator is feeding all electric items and charging battery at the same time. If the current has a negative sign, this means that the charging system is not able to power the electrical loads and a significant amount of the current required must be supplied by the battery, which is therefore discharging.

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.

Introduction
An accelerator position sensor (aps) is mounted on the throttle body of the
diavel, which measures the degree of aperture
of the throttle grip.
The throttle grip is connected to the sensor via two metal cables
The sensor transmits information to the ecu relative to the "torque ...

Introduction
The side stand button is located on the side stand. Together with the signal
from the clutch button and the neutral signal
generated by the gear sensor (transmitted to the engine control unit over the
can line), the side stand position signal is
used to enable or disable engine s ...
