The Dacia pick-up vehicles can be equipped with following types of alternators:
For vehicles of Dacia range, there are used alternators type 1114.200 and type 1180
(used for vehicles provided with AC).

The checking tests of the values for alternator type 1114,which are measures at
N 4 rpm, are performed when engine is cold.
The checking of the values at rpm N1, N2, N3, N5, are performed when the engine is
warm, i.e. after the alternator has been working for about one hour on voltage14 +/ - 0,1 V.
After measuring the value of the current at rpm N5 ,adjust the exciter voltage at
10 +/- 0,1 V and the voltage at the plugs level at 14 + / - 0,1 V. Adjust rpm NN at
6000 +/- 60 rpm and measure the corresponding value of the current, as soon as it is
stabilized.

B. CHECKING OF THE ADJUSTED VOLTAGE
For checking the adjusted voltage, perform an assembly similar to next diagram.
After starting the engine, accelerate until rpm is 300 rot/min then increase the alternator
current from 10 A to 43 A ; the voltage must be between 13,8 and 14,5 V, at a temperature
of 22 ° +/- 5 ° C.
If this condition is not accomplished, check the voltage; if also this is correct, replace the
electronic regulator and check again. If defect persists, check by dismounting, the alternator
components.
