DISMOUNTIN G
Disconnect the battery.
Dismount the air filter.
Disconnect:
- pipe 1 for fuel supply;
- pipe 3 for fuel return;

REMARK:
For EURO 00 and EURO 96, the
pre ssure c ontrol ler and return pi pe are
placed in t he fuel tank.

ALTERNATOR – STARTER
B. The indicator is lighting, engine being running.
This shows a charging failure, which may be caused by:
- alternator driving belt broken, charging wire connected to alternator is broken (+ per-
manent);
-alternator failure(rotor, stator, diodes or brushes);
- voltage regulator failure;
- an over voltage.
C. Client is claiming a charging defect, but the luminous indicator is correctly oper-
ating.
If the adjusted voltage is smaller than 13.5 V, check the alternator.
The defect may be caused by : -worn diode;
-b roken phase;
- collector wear or coal dust.
VOLTAGE CHECKING
Connect a voltmeter to the battery plugs and read its voltage value.
Start the engine and speed the e ngine till the voltmeter needle i s set on the adjusted voltage.
This voltage must be between 13.5 V and 14.8 V
Connect maximum of consumers; the voltage must still between 13.5 V and 14.8 V.
AT T E N T I O N !
In case electric arch welding is performed on vehicle obligatory disconnect the bat-
tery and the voltage controller (alternator).

DIAGNOSTIC
Special tool: CLIP tester and accessories for physical measurements.
CH ARGING CIRCUIT CHECKING
CLIP tester i s enabling the a lternator checking, by m easuring t he genera ted vol tage and
intensity with and without electric consumers.
REMARK: The ammeter pliers is of inductive type 0 ÷ 1000 A. Its mounting is done
without the battery disconnecting, enabling so the memorized data preserving and the
adapting values from the injection c omputer.
Mount the ammeter di rectly on t he alternator e xit, having t he arrow directed towards the
alternator.
The measurements are to be performed in three stages :
- measurement of the battery voltage with contact taken off;
- measurement without consumers of the adjusted voltage and generated intensity;
- measurement, with maximum of consumers, of the adjusted voltage and generated in-
tensity.
The values resulting further to the measurements, lead to following interpretations:
- voltage battery (without consumers) < 12.3 V – indicating discharged battery.
Without consumers :
- adjusted voltage > 14.8 V – indicating defective regulator;
- adjusted voltage < 13.2 or charging current < 2A – indicating charging failure.
With consumers:
- adjusted voltage > 14.8 – indicating defective regulator.
- adjusted voltage < 12.7 – indicating that alternator charging current must be checked
compared with its characteristics:
If the measured current is too small, check the following:
- alternator wear (collector brushes, etc);
- battery connections;
- engine mass stripe;
- drive belt tension.
If the measured current is correct and the adjusted voltage is too small, the cause may be: -the vehicle has too many electric consumers;
- the battery is discharged.

IDENTIFICATION
DIAGNOSTIC
Special tool : CLIP tester – TECHNIC for measuring the battery voltage and the absorbed
intensity in the starting stage.
OPERATION ABNORMALITIES THAT MIGHT BE NOTICED
- Battery failure = large voltage drop on starter during engine starting stage.
- Blocked starter = the absorbed current is very high.
- Solenoid failure = the absorbed current is very low.
In order to perform the measurements, it is necessary the engine drive by means of the starter,
but stopping the engine starting.
To do that, disconnect the RPM sensor (located on clutch casing).
REMARK:
After performing this checking, erase by means of the CLIP tester, the possible failures
memorized by the computer.

ANTI-STARTING INDICATOR
When setting the contact on, UCE injection is receiving from UCE DECODER a code, whi
ch is compared
with the one previously memorized; if the two codes are matching, then the engine starting is author ized.
After contact setting on, anti-starting indicator which was previously blinking, will light for
three seconds then it will go off, confirming in this way, the key recognizing.
If the key is not good, after setting on the contact, the anti-starting indicator will start blinking
faster and the engine starting will be impossible.
OBSERVATION:
For details regarding the vehicle anti-starting system, see chapter 82 “Anti-starting system”.

IDLING REGIME CORRECT ION SUB JECT TO B ATTERY VOLTAGE AND TO
ELECTRI C BA LANCE ON VEHICL E.
Th is correction is dedicated to the compensation of the voltage drop due to the electric consumers
starting, when the battery is weaker charged. In this purpose, engine RPM is increased, allowing in
this way the alternator rotation increase and consequently of the battery voltage.
More the lower is the voltage, more important the applied correction is. So, a variable correction
is applied, starting when voltage is reaching 12,8 V. The correction is starting from the nominal
idling RPM and may increase with maximum 150 rot/min additional.
