STARTER DOES NOT WORK
Check the battery voltage and
the terminals state.
Dead battery; charge the battery;check
the charging circuit.
Charged battery : clean and tighten
Terminals.
Check if solenoid is supplied when
switch on contact with the key.
Solenoid is not supplied.
Check the ignition contact.
Ignition contact does not work:
replace the ignition contact.
Solenoid is supplied; dismount the
starter and check it;
Ignition contact working; the supplied
wire of the solenoid is interrupted or
disconnected.

IGNITION AND INJECTION
17 - 1
The following spark plugs are to be used for Dacia vehicles:
The inducing voltage of the spark plug is 4 – 8 KV. The maximum voltage difference between
the spark plugs, measured on the engine is 2 KV.
The distance between the electrodes is set by means of thickness gauges at the preset values,
according to the spark plug type.
The spark plugs may be checked on the engine itself by means of a special tester for spark
plugs or by testing the inducing voltage.
Mount he spark plug on the tester; increase the pressure to 12-13 bars and observe the
spark aspect:
- the spark plug should be replaced as inadequate, in case the spark is reddish and dispersed
or in case there is an external discharge;
- the spark plug is adequate in case the spark is blue and is between the electrodes.
Constructive components of the spark plug:
The following spark plugs are to be used for Dacia vehicles:

MONO - MOTRONIC INJECTION SYSTEM ( MA 1.7 )
OPERATION PRINCIPLE
The BOSCH MONO-MOTRONIC injection system is a (á, n) type, where:
á = angle indicating the position of the valve and reading the engine load.
n = engine rotation
These are the principle information for the electronic control unit (computer), used for
determining the basic injection time (t
i
); this basic time value is corrected depending upon
the variation of the parameters with lent evolution: T engine, T suction air, lambda value
(ë), battery voltage.
The electronic control unit does the ignition advance calculation and the ignition coil
control for the MONO-MOTRONIC injection system, taking into account the evolution
of the parameters: T engine, T air, n (engine rotation).
The system is available and does not require adjustments. It is a self-adapting type
system, which corrects itself the parameters during the engine running, taking as well into
account its wearing during the run.
