This section of the manual describes the start-up system and provides information to check for its correct
operation.
Removal and fitting operations are also described.
Starter motor maintenance instructions
1. Pay attention when locking the starter motor terminal or the battery terminal properly; if the connection
is not correct, there is serious risk of overheating due to a strong passage of current upon starting the
vehicle.
2. Before removing the starter motor, disconnect the battery negative (-) terminal. Then, disconnect
terminals (+B, ST) from the motor. Since battery voltage is always applied to terminal +B of the starter
motor, carefully observe the removal sequence to avoid causing a short circuit in the battery, which is
extremely dangerous.
3. When refitting the starter motor, make sure to tighten the bolts observing the relevant locking torque.
Any incorrect refit can result in early wear of pinion teeth or flywheel crown, or even cracking of the
crankcase.
Inspection with starter motor fitted
1. Take the gearshift lever to neutral. Pull the
handbrake lever.
2. Disconnect the ignition coil connector so that the
motor does not start.
3. Turn the ignition switch to ST. Check that the
motor starts running.
4. If the motor does not turn, check if the battery is
damaged or discharged. Perform the cable har-
ness continuity test.
5. If despite the above checks, the starter motor
does not start, remove the motor and check it.
