OPERATION - FAULT FINDING
These vehicles are fitted with alternators with in-
ternal ventilation, an integral regulator and a
warning light on the instrument panel which ope-
rates as follows :
- when the ignition is turned on, the warning
light illuminates,
- when the engine starts, the warning light ex-
tinguishes,
- if the warning light illuminates again when
the engine is running, there is a "charging"
fault.
LOOKING FOR FAULTS
The warning light does not illuminate when the
ignition is turned on.
Check:
- the electrical connections are correct,
- the bulb is not blown (to do this, earth the cir-
cuit; the bulb should illuminate).
The warning light illuminates when the engine is
running
There is a charging fault which could be due to:
- the alternator drive belt being broken or the
charging cable being cut,
- internal damage to the alternator (rotor, sta-
tor, diodes or brushes),
- regulator fault,
- an excess voltage.The customer complains of a charging fault and
the warning light operates correctly.
If the regulated voltage is less than 13.5 V, check
the alternator. The fault could be caused by:
- a destroyed diode,
- a cut phase,
- track contamination or wear.
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 voltmeter needle stabilises at the
regulated voltage.
This voltage should be between 13.5 V and 14.8 V.
Connect as many consumers as possible, the
regulated voltage should remains between 13.5 V
and 14.8 V.
IMPORTANT: if arc welding is carried out on the
vehicle, the battery and the regulator must be
disconnected.

and shaft (4), removing through opening (5),
REMOVAL
With the vehicle on a 2 post lift, disconnect:
- the battery,
- the alternator electrical connections.
Remove:
- the power assisted steering belt by slackening
the three bolts (1) and the nuts (2) for the ten-
sioner, E 7 J and
K 7 M engines

Press downwards on the front axle assembly to
make removing the alternator easier through the
front right hand wheel arch.
REMOVAL
Refitting is the reverse of removal.
Special notes:
- do not refit the old drive belt, renew it,
- refer to section 07 for tension values. E 7 J and

REMOVAL
(there are no special notes for engines fitted with
power assisted steering)
To release the alternator shaft the following must
be removed:
- the mounting bolts (1) for the coils,
- the two bolts (2) from the coil mounting.
Slacken bolt (3) then slide the mounting down.

REMOVAL
Disconnect:
- the battery,
- the alternator electrical connections.
Remove the mounting bolt for the diesel fuel pipe
retaining bracket and move it to one side.

Slacken bolt (A) then bolt (B), to just past the
shoulder, while holding the automatic tensioner
plate with a 9 mm wrench (Eg. : FACOM J 151 rat-
chet), then slacken the belt by moving the ratchet
in the direction of the arrow. F 8 Q engine
with AC
98837-1R
Remove:
- the lower timing cover,
- the belt,
- the alternator mounting bolts,
- the alternator.
REFITTING(Special note)
Refitting is the reverse of removal.
The belt is tensioned by moving the automatic
tensioner plate against the stop at bolt (B), wi-
thout forcing it, using a 9 mm wrench (Eg. :
FACOM J 151 ratchet ).
98837-1R1
NOTE : do not refit a belt once it has been remo-
ved.
