OPERATION - FAULT FINDING
These vehicles are equipped with alternators with
internal ventilation and integral regulator, also
with a warning light on the instrument panel
which has the following functions :
- when the ignition is switched on, the light illu-
minates
- when the engine is started the light extin-
guishes,
- if the light illuminates whilst the engine is
running there is a "charging "fault.
LOOKING FOR FAULTS
The warning light does not illuminate when the
ignition is switched on.
Check:
- all electrical connections are good.
- the bulb has not blown. (Earth the circuit and
the bulb should illuminate).
The warning light illuminates when the engine is
running.
This indicates a charging fault which could be
caused by :
- the alternator drive belt being broken or the
charging wiring being cut,
- internal alternator damage (rotor, stator,
diodes or brush),
- a regulator fault,
- excess voltage.The customer complains of a lack of charge and
the warning light is operating correctly.
If the regulated voltage is less than 13.5 V, check
the alternator. The fault could be caused by :
- a diode which has been damaged,
- a phase which is cut,
- contaminated or worn tracks.
Checking the voltage
Connect a voltmeter across the battery terminals
and read the battery voltage.
Start the engine and increase the engine speed
until the needle registers a stable regulated
voltage.
This voltage should be between 13.5 V and 14.8 V.
Connect as many consumers as possible, the
regulated voltage should be between 13.5 V and
14.8 V.
IMPORTANT: if arc welding work is to be carried
out on the vehicle, the battery and regulator
must be disconnected.

OPTIMA 5800 Diagnostic station
CHECKING THE CHARGING CIRCUIT USING THE DIAGNOSTIC STATION
The OPTIMA 5800 diagnostic station allows the alternator to be checked by measuring the voltage and cur-
rent delivered , with or without electrical consumers .
NOTE : the Amps clamp used for this station is of the inductive type (measurement range: 0 to 1 000 A). It
is fitted without disconnecting the battery, which allows the the computer memory and adaptive informa-
tion to be saved.
Fit the Amps clamp directly at the alternator output, with the arrow pointing towards the alternator (any in-
correct positioning is detected by the station).
The measurement is carried out in three stages :
- measurement of the battery voltage, ignition off,
- measurement of the regulated voltage and of the current supplied, without consumers,
- measurement of the regulated voltage and current supplied, with a maximum number of consumers.
On completion of the test, the values noted will lead to the following fault finding messages :
- Battery voltage, no load < 12.3 V = battery uncharged.
Without consumers :
- Regulated voltage > 14,8 V = > regulator faulty ,
- (regulated voltage, no load < 13.2 V) or (charging current< 2 A) = >charging fault.
With consumers :
- Regulated voltage > 14.8 V = > regulator faulty,
- Regulated voltage < 12.7 V = > it is necessary to check the alternator supply in relation to its specifica-
tions :

If the electrical supply measured is too low, check:
- the wear of the alternator (brush...),
- the battery connections,
- the engine earth strap,
- the conformity of the alternator,
- the belt tension.
If the electrical supply measured is correct and the regulated voltage is too low, the alternator is not faulty.
The cause of the problem is to be attributed to one of the following sources :
- the vehicle has too many electrical consumers,
- the battery is discharged.

REMOVAL
Place the vehicle on a two post lift .
Disconnect the battery as well as all electrical
connections leading to the alternator.
Remove :
- the alternator belt and that of the power as-
sisted steering pump for the D7F engine (if
fitted),
- the alternator.
REFITTING
Refitting is the reverse of removal.
D7F Engine
Tensioning of the alternator belt is carried out
using the locally manufactured tool shown be-
low (threaded rod 100 mm in length (X) and three
M6 nuts).

OPTIMA 5800 Diagnostic station
CHECKING THE STARTER MOTOR USING THE DIAGNOSTIC STATION
Checking of the starter motor is carried out using the OPTIMA 5800, by measuring the battery voltage and
the current absorbed in the engine starting phase. The following operation faults may be highlighted :
- a fault in the battery ( the voltage falls during the starting phase),
- locking of the starter motor (the current absorbed is too high),
- a fault in the engine starter gear (the current absorbed is too low).
In order to carry out the measurement, it is necessary to stop the vehicle from starting :
- for D7F and E7J engines : disconnect the engine speed sensor (located on the clutch housing ,
- for
F8Q engines : disconnect the pump electrical solenoid and isolate the terminal.
NOTE :
- an open circuit on the engine speed sensor or the ignition creates a fault memorised by the injection
computer, this fault must then be erased from the memory using the
XR25 (see "Injection" section),
- if the engine is fitted with an immobiliser, it is sufficient to lock the doors using the remote control.
