Fault finding – Features
The function of the charging circuit is to:
●Ensure electrical energy is supplied to the vehicle whilst respecting the dynamic performance constraints
of the engine and transmission assembly: the alternator resisting torques and the torque gradients
measured must be managed.
●To control alternator loading and load shedding during engine management authorisation or variation of
the electrical load.
●To ensure the quality of the on board network voltage in terms of the voltage level and variation
(voltage gradient management).
●To optimise the battery charge by applying a voltage to its terminals correlating to its initial charge status
(in sleep mode) and to its internal temperature.
●To inform the engine management about the mechanical power taken from the accessories pulley,
the alternator charge rate and the rotor excitation current value.
●To run fault finding on the charging circuit: “Battery” warning light display.
The function of the starting circuit is to:
●Start the vehicle during a starting request with the ignition key if necessary. New Twingo

ALP3 The starter is noisy when starting
NOTESTest the condition of the battery (see MR 413, 80A, Battery).
Check that the noise is actually coming from the starter.
Try to start the engine.
At what point is the noise heard?
Starting phase Just after the engine has started
Check if the starter is
insufficiently secured
Is the starter correctly secured?Tighten the starter mountings (see MR 411, 16A,
Starter: Removal - Refitting).
Remove the starter and check that the centring
pin is present. Check the condition of the pinion
and check the entire ring gearInhibit the engine injection (see 13B or 17B,
Interpretation of commands), activate the
starter for 2 seconds and release the key.
Is a fault noticed?Does the starter continue to run after the key is
released?
