Engine
7- Low trailing speed
High electrical absorption
Carry out a test of the engine rotation (example: possible melting of the bushes) and if no anomalies
are found, replace the starter motor.
8- Low trailing speed
Low electrical absorption
Repeat the test, bridging the power terminals of the starter remote control switch or even better replacing
them.
Check the new values.
YES go to 12 NO go to 13
9 - High trailing speed
Low electrical absorption
The engine turns too freely, check the compression end pressure.
If the values are not correct proceed as follows.
10 - The starter motor works properly.
11 - Check the rotation of the armature.
12 - Replace the starter remote control switch.
13 - Test the battery again and if necessary replace the starter motor.
N.B.
IF THE TRAILING SPEED OF THE CRANKSHAFT IS LOW AND COMBINED WITH STRANGE
NOISE, CHECK THE FREEWHEEL OF THE TORQUE LIMITER (SEE THE "FLYWHEEL AND
STARTER SYSTEM" CHAPTER).

Ring gear and freewheel coaxial to the flywheel.
The starter system has a transmission between the motor armature and engine shaft equipped with
freewheel coaxial to the flywheel and torque limiter on the intermediate shaft.
The limiter is calibrated to 10 kgm (100 Nm); this component protects the structure of the engine and
the starter kinematic mechanism in the event of incorrect starting with consequent inverse rotations.
The freewheel is used for a sufficiently silent starting.
