The function of the charging circuit is to:
•Ensure that 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 when there is a starting request from the ignition key.

Remove the starter and check that the centring pin is
present. Check the condition of the pinion and carry
out a full check of the ring gear.Inhibit 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?
Fit a centring pin, or replace the
flywheel (see MR 370,
Mechanical, 10A, Flywheel:
Removal - Refitting), or replace
the starter (see MR 370,
Mechanical, 16A, Starting -
Charging, Starter: Removal -
Refitting).Starter control fault, check the entire starter
control line (see ALP1 The starter does not
work, continued 3 C).
Replace the starter (see MR 370, Mechanical, 16A,
Starting - Charging, Starter: Removal - Refitting).Make several attempts, waiting for 5 minutes
after 5 attempts (let the starter cool). If the result
is still the same after several attempts, replace
the starter (see MR 370, Mechanical, 16A,
Starting - Charging, Starter: Removal –
Refitting).
