Electric starting system
The key components of the electric starting system are a contactor (7) and a starter motor (6) fed by the battery (8).
The engine starting strategy is managed entirely by the engine ECU (28), which monitors the following inputs:
-Engine Stop switch on right-hand handlebar switch (1)
-Engine starter switch on right-hand handlebar switch (1)
-Neutral sensor (30)
-Side stand sensor (27)
-Clutch microswitch (43).
When these inputs are combined in the required manner, the engine control unit (28) enables engine starting.
The table lists possible engine starting combinations.
In accordance with the status of specific engine control unit inputs and the indications given in the table, the control unit
enables operation of the starter motor (ON status) when the START button is pressed.
X = generic status of neutral sensor, clutch, and side stand.
Safety device functions table
Starter motor
Power:
700 W with 12 V power.
Direction of rotation:
counter clockwise viewed from power take-off side.
The starter motor is highly compact and reliable and therefore rarely gives any type of problem. In case of malfunction,
ensure that the starter motor wiring terminal is properly tightened under the nut and shows no sign of corrosion. If the
terminal is properly tightened and free from corrosion, remove the starter motor and test it under no-load conditions (no
load applied to the shaft). Secure the starter motor to a test bench, making sure you do not damage the casing. Use a
fully charged 12 V battery for the test. Use battery-motor connection cables which are no longer than 70 cm and with the
same cross-section as the cable on the motorcycle itself. Connect the negative terminal of the battery to an unpainted
area of the starter motor casing and the positive terminal to its electrical terminal. The shaft of the starter motor should
