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.
