ELECTRIC EQUIPMENT PROTECTION
When performing a reparation at the vehicle, a set of actions must be taken to protect the
electric equipments of damages or to avoid a short-circuit which may lead to vehicle
burning.The battery is always disconnected by first disconnecting the negative terminal
and then the positive one.The connecting is done in reverse order.
Before starter operation, check if the battery is correctly connected ( negative terminal
connected at the mass, if the terminals are clean and well tightened. Never disconnect the
battery when engine is running order to avoid damages on voltage regulator or the alternator.
Disconnecting of the alternator, the voltage regulator, the battery and the repairs at their
connections are to be performed only when the engine is stopped ( the alternator is not
turning ).
In case of the battery connection to a charging rectifier, for charging purpose,( without
dismounting the battery from the vehicle), it is obligatory to disconnect the heavy wiring
from the battery terminals.
In case electric welding is performed on vehicle body, disconnect the battery terminals
and the connections plugs to the alternator
Some external or functional factors have a direct impact on the electric equipment,
which has as effect the modification in time of the nominal parameters of the component
elements of the electric equipment, affecting their reliability and operating safety.
The main affecting factors are:
-
Temperature – some elements being placed next to the engine, are obliged to operate
at high temperatures.
-
Humidity – the electric equipment components are operating in a an environment
where they may be in contact with water, oil or fuel, consequently there is the danger of
contacts oxidation and destruction of the electric wires insulation.
-
Variable running condition – the running condition of the engine being variable, it
signifies that electric equipment elements which are geared by the engine will also have a
variable running condition.
-
Requests of energy sources – when starting the engine by means of the starter, the
battery is requested at high currents and after engine starting, due to the variable number
of consumers and to the variable rotation regime of the alternator, the battery is forced to
pass, in a short period of time, from unloading regime to loading regime and viceversa.

H ARACTERISTICS
The DACIA vehicles are equipped with the following types of batteries:12V/45 Ah ,
55 Ah, and 60 Ah. The battery is attached to its support by means of a clip, supported by
two bars. The battery is connected to the vehicle electric system with the negative terminal
to the mass. The battery terminals and cables clips shall be clean and well tightened, after
which they shall be greased with neutral grease.
The electrolyte level shall be maintained 10 – 15 mm over the upper edge of the separators.
If lowering of the electrolyte level is noticed due to evaporation, the refilling is to be
done only with distilled water or free of minerals water.
Never empty the electrolyte off the battery.
The charging degree of the battery may be established by means of the densimeter,
comparing the values obtained, with the ones of the following table:
ELECTROLYTE PREPARATION
The electrolyte is obtained from sulfuric acid for batteries STAS 164 /75 and distilled or free of
minerals water, without impurities.
When preparing the electrolyte , use vessels and funnels made of materials resistant to acids
(lead, glass, ceramics) that not made impurities or elements that should discharged early the battery.
When preparing the electrolyte , pour the acid into the water ; never pour water over the acid.
There is danger of explosion !
When preparing the electrolyte, use vessels and funnels made of lead, glass or ceramic, materials
which do not react with the sulfuric acid and are not producing impurities or compounds which
may lead to early self discharging of the battery.
Depending on the climate area where the battery is used, the electrolyte density measured at
15° C, must be:
- 1,23 g / cm ≈ for tropical climate;
- 1,28 g / cm ≈ for temperate climate;
- 1,30 g / cm ≈ for cold climate.

To prepare electrolyte of a certain density, for each liter of distilled water, add a quantity
of sulfuric acid as per a.m. table.
BATTERY CHARGING
The batteries are charged in special rooms, well ventilated, where the working
temperature shall be of 20 – 25° C.
The dry-discharged batteries shall be filled with electrolyte with 1,26 g/cm≈ density
at a temperature of 15 – 25 °C until the level of the electrolyte is 10 – 15 mm over the
upper edge of the separators; after a 2 – 3 hours pause, during which the electrolyte
penetrates the plates, check again the level, and refill with electrolyte of same concentration.
The battery prepared in this way, shall be charged by a continuous current source
(rectifier), which will be connected with the ( + ) terminal at the ( = ) terminal of the battery
and the ( - ) terminal at the ( - ) terminal of the battery.The charging shall be performed
only when the electrolyte temperature is not higher than 30°C, and the battery will be
immersed in a cooling vessel, with the level at 2/3 from the battery height.
The battery charging is performed in two stages, the battery without plugs, as follows:
- stage I - adjust the charging current ( I
I
) to 10 % of the battery nominal capacity
( I
I
= C n / 10 ) - and shall be maintained at a constant value until the voltage per element
reaches 2,4 V. The temperature of electrolyte shall not be over 30° C; in this case the
charging shall be stopped in first stage I and follows the charging in second stage II.
- stage II - adjust the charging current ( I
II
) to 5 % of the battery nominal capacity
( I
II
= C n / 20
)and shall be maintained until the end of charging, when can be notice an
active gas emission from all elements, the electrolyte density increases to 1,28 c / cm≈ and
the voltage reaches at 2,6 – 2,75 V / element, these values being necessary to remain
constant during 3 hours, in case of a good battery.
