ST ARTING AND CHARGING
The position of the alternator i s blocked.
The engine is revolved thre e and a half cra nkshaft turns;
The reading end of t he MOT. 1505 measuring device is placed in the measuring area;
The tension in the belt is measured;
It is checked whether t his fits i nto the mounting tension tolerance; if not, the belt will
be stretched again until the recommended tension ( 263 Hz +/- 10%) is reached.
The inspection a nd t he a djustment of the belt a re done with t he e ngine at ambient
temperature . Tighten at the require d moment, the alternator a ttachment screws :
- screw M10(lower attachment)-5 daNm
-screwM10 (upper attachment)-2.2 daNm.
Remark: Once dismounted, a belt is not to be remounted, but replaced.

(in the air -conditioning variant)
The car is placed on a two-column lifting stand;
The electric connections are uncoupled from the battery;
The following are taken apart: -the top scre w of the alternator;
-the belt of the alternator;
The right-side front wheel of the car is taken apart;
The car is suspended;
The two screws fixing the shock-absorber on the steeri ng swivel stand are taken off;
The steeri ng swivel stand is lowered and the right-side planetary tra nsmission is taken
off the planetary pi nion of the gearbox; The electric conductors of the alternator a re disconnected;
The screw of the alternator is taken off;
The alterna tor is taken apart laterally past the right-side planetary tra nsmission.

E-MOUNT ING
The taking-apart opera tions are done in the reverse order;
The carrying belt of the alternator is stretched to obtain the mounting tension recom-
mended (263 Hz +/- 10% );
The position of the alternator i s blocked;
The engine is revolved thre e and a half cra nkshaft turns;
The reading end of the MOT. 1505 measuring device is placed in the measuring area;
The tension in the belt is measured;
It is checked whether t his fits into the mounting tension tolera nce; if not , the belt will be
str etched again until the re commended tension ( 263 Hz +/- 10%) is reached.
The i nspection and the adjustment of the belt are done with the engine at ambient
temperature .
Tighten at the require d moment, the alternator a ttachment screws :- screw M10 (lower attachment)-5 daNm
-screw M10 (upper attachment)-2.2 daNm.
Remark: Once dismounted, a belt is not to be remounted, but replaced.

IDENTIFICATION

E7J - A-2/60 D 907 - M00 2T 13581
DIAGNOS TICATION
S pecial device: CLIP - SAGEM-TECHNIC TESTER which measures the battery
voltage and the intensity absorbed by the starter.
ANOMALOUS FUNCTIONING THAT CAN BE SETTLED
-Battery failure –contact drop on the starter when starting the engine.
-Blocked starter (t he absorbed curre nt is very high);
Coupling relay defect (the current absorbed is very weak).
In order to do the measurements one must carry t he engine in starter mode, thus pre -
venting the engine to run.
To do t hat, the revolution sensor (located in the c lutch cra nkcase) should be t aken apart .
Remark: After doing these tests, erase the possible defects memorized
by the calculator with the tester.

The car is put on a two-column lifting stand;
The battery of storage cells is disconnected;
The screw-nuts fixing the degassing vessel are taken apart.
The degassing vessel is re moved (without disconnecting the link conduits) to the fore
part of the car i n order to facilitate access to the screws fixing the starter; The screws fixing the command bar on the connecting rod of the gearbox are taken off
(the jack is retrieved);
The screws no. 1 fixing the start er are taken;
STA RTER
The car is suspended;
The electric connectors of the starter are disconnected;
The start er is taken out through the bottom of the engine compartment. R

The taking-apart opera tions are done in the reverse order.
The screws are tightened at a 4.4 daNm couple.

The system is made up of:
- electronic control unit;
- double ignition coil;
- four sparking plugs;
- spark plugs.
DES CRIPT IO N OF FUNCT IO NING PRINCI PL E
Accordi ng to the data received from
various sensors, but essentially according
to the revolution ratio and the load of t he
engine, the electronic control uni t will de-
termine the ignition advance; it will also
identify the cylinders that are set at the
upper center point and, consequently, will
command the re spective coil. This c auses the spark at the level of the
two cylinders t hat are at the upper center
point, thus interrupting the m ass-setting of
the respective coil. T
HE CO IL
The system c ontains a doubl e c oil, con-
trolled by the calculator.
Coil no. 2 has an electric connector (1) with
four ways, whi ch si m ultaneousl y produc e

commanded by pin no. 32 of the i njection cal-
culator, and on cylinders no. 2 and 3 when it

culator.
