OPERATION / DIAGNOSTIC
These vehicles are equipped with alternators with internal ventilation, incorporated voltage
regulator, and charging indicator on the instrument panel, which must operate as follows:
-w hen the contact is set on, the indicator is on;
-af ter engine starting, the indicator is off;
-i f indicator goes on during engine running, then it shows a charging failure.
INCIDENTS SEEKING
A. The indicator is not lighting when setting the contact on
Check : -the electric connections must be well done;
- the indicator bulb is not worn (when the circuit is mass connected, the bulb must be on).

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).

Nominal intensity 7 5 80
Minimal intensity, generated by the alternator with
maximum of consumers under operation 5 1 60
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.

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”.
AT T E N T I ON!

Injection system
only when the engine is stopped and t he contact off.
If the contact is on or the engine is running, do not loosen or disconnect the battery
terminal s. It is forbidden the battery replacement on t he vehicle i f the engine is running
or the contact on. Loosen or rusty contacts at battery terminals and imperfect connections at the
injection system wiring are not allowed. It is forbidden the engine starting with the battery connected to a charging / starting
unit. The battery recharging is t o be pe rformed only aft er disconnecting it from the vehicle
wiring and by means of a c harging unit with 12 V v oltage.

If vo ltage > Min, the batte ry is discharged :
C heck tha t charging voltage is correct with and without consumers.
Under contact If voltage > Max, the battery i s, probabl y, too charged:
C heck tha t charging voltage is correct with and without consumers.
If voltage < Min, the charging voltage is to weak :
C heck that charging circuit in order to dete ct the origin of this problem.
At idling If voltage > Max, t he charging voltage is too strong:
The alternator -charging regulator is damaged.
Fix this problem and check the ele ctrolyte level in the battery.

DISMOUNTIN G
Make the unit functioning for at least 10 minutes (if the unit permits).
Drain the circuit in the charging equipment.
Measure the quantity of recovered refrigerated fluid.
Release the access to the component that is needed to be changed.
Disconnect the connections.
In order to avoid the moisture infiltration, protect with protection covers.
Dismount the component.
REMOU NT I NG
