INTENSITY (A)E NGINEE 7J
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.

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.

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.

ATTENTION !
In case of acid splashes on body, abundantly wash with water all affected parts.
If eyes have been touched, urgently call for a doctor.
1. DANGER = EXPLOSION RISK
During battery charging, connected to a charger-rectifier, oxygen and hydrogen emissions are
occurring. These gases emission is stronger when the battery has reached the complete charge
condition and the produced gas quantity is in direct connection with the charging current.
The oxygen and hydrogen are associating in the free spaces, at the plates surface, forming a
detonate mixture, which is very explosive. The littlest spark is sufficient to generate an explosion,
followed by the battery case brooking and a cid splashing in the proximate environment. The
persons, who are a round, are in da nger t o be hurt by t he e xploded case chips or by the acid,
which may come i n contact with the eyes, hands, or face.
ATTENTION !
Strictly observe the following recommendations:
- before connecting or reconnecting a battery, ensure that all consumers are shouted off.
- during battery charging in a room, using a charger-rectifier, turn it off before connecting or
reconnecting the battery to this one;
- do not place metallic objects on t he ba ttery for not producing a short-c ircuit between i ts
pl ugs ;
- never bring closer to a battery, a n open flame, a welding lamp or another fire source.
THE ELECTRIC EQUIPMENT PROTECTION
In case of an intervention on the vehicle, some measures must be taken, for the electric equip-
ment protection against damages or for avoiding a short-circuit that may lead to vehicle firing.
The battery is to be allwith disconnected by first disconnecting the negative plug and then t he
positive one. Connection is to be done by performing the disconnecting operations in the reverse
order.
Before starter acting, check if the battery is correctly connected (the negative plug connected
to the mass), and if the plugs are clean and well tightened. Never disconnect the battery when the
engine is running, in order not to damage the voltage regulator, the alternator or some components
of the vehicle checking electronic systems. The alternator, voltage regulator disconnecting, and
the interventions at their connections, are to be performed only when the engine is stopped (the
alternator is not turning) and the contact is taken off. In case the battery is connected to a charger-rectifier, for charging (without dismounting the
battery off the vehicle), it is obligatory to disconnect the wiring from the battery plugs.
