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

ALP4The starter rotates slowly from the outset.
The rotation speed of the starter decreases rapidly.
The starter causes the warning lights on the instrument panel to
become very dim
Applicability: All types
NOTESTest the wiring (TEST3).
Test the status of the battery (see 80A, Battery).
If the fault is still present, replace the starter (see MR 411, 16A, Starting - Charging, Starter: Removal -
Refitting).
