7.1. General information
The tension in the system of the electric equipment of the cars of Hyundai does 12 V. Elektrooborudovaniye happens according to the only scheme of wire — the negative conclusions of fountains and the consumers of the electric power join a hoof of the car that executes the function of the second wire – "weight". The provision of power of all the electric devices carries forward out of the battery of the reloaded main and acid type of the creator of the alternate current.
In the service of present section and the repair of some elements of the system of the electric equipment of side they are described. Besides, the diagnostic one of bad functioning of the electric equipment considers herself.
The security measures during the work with the electric equipment
In the moment of the repair of the electric equipment and a system of provision of power of the motor desconectam a wire of - the capture of the battery recarregável.
Substituting locks of security screwdrivers and the metal instrument prohibits to use as it can lead to the short circuit in electric chains of equipment.
There is prohibited desconectar the panel of command of the ignition and the battery recarregável in the work motor as of that the regulator of the tension and the elements of the electronic equipments of the car can fail.
Checking chains of the electric equipment it is prohibited to close "in the mass" of a wire (to check the usefulness of chains "of a spark") to avoid the failure of elements of the electric equipment.
"30" the creators are even prohibited of joining a conclusion of "meditating" (to check the Repair of the creator "in a spark") as it will lead to the failure of diodes of the block vypryamitelny of the creator quickly. There is possible the creator checks in the car only the voltômetro and the ampermeter. To avoid the failure of diodes of the block of vypryamitelny it prohibits to check them the meter megohm or they fed the lamp of control more than 12 V and also to check such devices of a chain of the electric equipment in the car without lack of interest of wires of the creator. There are necessary winding conclusions check the resistance of the isolation of a curve of the fixed part of the electric motor of the creator to tension increased in a retired creator of the car in the fixed part of the electric motor desconectadas of the block of vypryamitelny.
When it executes electrowelding it works in the car is necessary desconectar wires of captures of the battery recarregável and conclusions of the creator.
Do not concern elements of the system of ignition and wires of high voltage in the work motor.
Do not put a wire of the low and high voltage in a braid.
In recarregam through the porter of the battery recarregável in the car desconectam wires of captures of battery.
Diagnostic of bad functioning of electric equipment of side
The basic electric element, several switches, the alternation, the electric motors, the locks of security, the insertions fuses or the switches of a chain that one connects with this element and also the driving and service of captures of contact of the connection of a basic element with the battery recarregável and "the mass" of a body can be a part of a typical electric chain. For the simplification of the inquiry of bad functioning of electric chains the schematic electric circuits and the schemes of electric connections are supplied in the management.
Before beginning works in the elimination of bad functioning in any electric chain, attentively it studies the corresponding scheme as much as possible to have a clear vision of his functional objective. The circle of the resolution of problems is narrowed normally due to the gradual definition and an exception of elements normally they work of the same outline. In the moment of the simultaneous failure at the same time several burn of outlines or elements - out of the lock of corresponding security or violation of the base it is the most probable cause of the refusal (the different chains in many cases can be isolated in a lock of security or a conclusion of the base).
The failures of the electric equipment very often explain for the elementary reasons, like the corrosion of contacts of captures, failure of a lock of security, burn - out of an insertion fuse or the damage of the alternation. Execute a visual inspection of a condition of all the locks of security, driving and contact with captures of a chain before beginning the most concrete check of the usefulness of his component.
In case of the application to investigate of diagnostic unities carefully they plan (according to the enclosed electric circuits), in
which points of an outline and in what sequence is it necessary to join the device for aims of the most efficient detection of the bad functioning.
The prover of electric chains or the voltômetro (the lamp of control of 12 volts with the group of wires they join also can be in use), indicative of interval of a chain (I bread with embroidery samples) including a lamp, provision itself of power and group of wires join that it is between the main diagnostic unities. Besides, it is always necessary to have in the car the group of the wires of the launch of the motor of a foreign fountain (the battery recarregável of another car) equipped of clips as "crocodile" and there is desirable the switch of an electric chain that can be applied to detour and connection of several elements of the electric equipment in the diagnostic one of a chain. I eat already if it mentioned before the initial check of a chain through the diagnostic equipment, determine for schemes of the place of his connection.
The checkings of the voltage of provision are executed in case of the violation of an electric chain. Join one of wires of a prover of electric chains or to the negative capture of the battery recarregável, or to the point of hoof of the well established car. Join other enclose of a prover to the contact of the capture of the checked chain, preferivelmente to beside the battery recarregável or a security lock. If the lamp of control of a prover is illuminated by it, the provision voltage in this part of a chain is this confirms the usefulness of a chain between this point of a chain and the battery recarregável. Work of the same way, investigate the rest of chain. The detection of the violation of the voltage of provision demonstrates the existence of the bad functioning between this point of a chain and the last thing of the checked one before (where there was a provision voltage). In most of the cases the cause of the failure is composed in weakening of captures of contact and damage of contacts (oxidation).

PREVENTION
Remember that some chains of the electric equipment of side receive the food only if the ignition key is in the provision "of the DONKEY" (parking) or "WHEN" (movement) "WAS" "RUN".

Inquiries of the place of short circuit. One of methods of the inquiry of the short circuit is the extraction of a lock of security and the connection instead of her of a cloth with samples of embroidery of lamp or the voltômetro. The tension in a chain has to be going away. Pull the driving, looking at a cloth with samples of embroidery of lamp. If it begins the lamp blinking — somewhere in this wires braid there is a short circuit "in the weight", possibly, caused by a mastication of the isolation of wires. A similar inspection can be executed for each one of component ones of an electric chain being lit of the corresponding switches.
Basic usefulness check. This inspection is executed for the definition of the confidence of the base of an element of a chain. Desconecte to battery recarregável and sole one of wires of a lampyprobnik, having the provision of independent power, to the obviously quite established point. Join other enclose of a lamp to the checked braid of wires or the contact of the capture. As it is necessary to be (and vice-versa).
An inspection for lack of the interval is executed for the detection of intervals of an electric chain. After the power of an outline they check it through a cloth with samples of embroidery of lamp with the provision of independent power. Join wires from cloth with embroidery samples to both ends of a chain. If it illuminates the lamp of control, there is no interval in a chain. If it does not illuminate the lamp, then it demonstrates the existence in a chain of interval. In the same way there is possible also to check the usefulness of the switch, when a cloth adhered with embroidery samples to his contacts. In the moment of transfer of the switch the situation "Incl". the lamp from a cloth with embroidery samples will illuminate.
Location of the place of interval. In the diagnostic one of the suspect in the existence of the interval of the siege of an electric chain visually to find a cause of the defect seems quite difficult like the captures inquiry in the existence of the corrosion or the violation of the quality of his contacts is complicated because of the access contented by them (normally the captures are closed by the case of the capture of contact). Sharp to contract of the case of the capture in the sensor or a braid of his wires in many cases drives to contact with the restoration. Do not forget of him in attempts of the location of a cause of the failure of the suspect in the existence of the interval of a chain. The refusals movediçamente appear that there can be a consequence of oxidation of captures or violations of the quality of contacts.
The diagnostic one of bad functioning of electric chains does not represent a difficult task in the condition of a clear idea of the fact that the electric current brings near to all the consumers (a lamp, an electric motor, etc.) of the battery recarregável in wires was seeing switches, the alternation, locks of security, insertions fuses, and soon it returns to the battery "for the mass" of a hoof of the car. Any problem joined with the failure of the electric equipment can be caused for the interruption in the provision in them by electric current of the battery or the return of the current to the battery.
Wires, locks of security and alternation
The protection of electric chains of the car against the short circuit is provided of application of locks of security, switches of chains and insertions fuses. It is easy to distinguish the lock of security down burned of his bag of transparent, useful plastic for the inquiry. Attentively examine a lock of security. If the security lock exgently looks normally, but the suspicions in his bad functioning remained, check the condutividade between the contacts of the type of knife that acts of his case.
When it substitutes security it is locked by the complaisance of clock of the value of face of a new lock of security to the value of face of an old man. The locks of security calculated according to several current can look exgently equally, therefore, the special attention must be given to the marking. The substitution of the lock of security is lowered by me burned in the calculated one in the least thing, and specially in big, current it is undesirable. Each precise electric chain of the degree different from the protection. It looks what will mark in case of a security lock it corresponded to the current according to which one makes calculations
corresponding chain. If the security lock substituted immediately if it fuses, is unreasonable to continue his substitution. First of all it is necessary to define and to withdraw the cause of his burn it had been. In most of the cases the short circuit appears in an electric chain caused by interval or damage of the isolation of a wire.
Insertions fuses
The protection of some electric chains executes for the inclusion in them of insertions fuses. Normally the insertions are in use for the protection of the chains that are not equipped of security locks like the chain of the system of the ignition.
The insertions fuses are similar to security locks in the sense that an exit they out of the Repair (oplavleniye) easily defines visually.
Since the substitution of an insertion fuse desconecta a wire of the negative capture of the battery recarregável. Take the insertion down burned and establish new at his place. Before the substitution of an insertion certainly they try to define the reason of the overload that caused an exit of insertion out of the Repair.
Switches of chain (thermal alternations)
The thermal alternations serve for the protection of such elements as electric walks of regulators of window, locks of doors and the electroproofreader. Some chains switches are installed in the block of meeting. The return of thermal alternations to an initial state in some models is executed automatically, this is in the moment of the emergence of an overload in a chain the thermal alternation desconecta-se immediately, shortly afterwards that the cooling reverts to the original state. If the return of an outline in the position does not happen, it is necessary to check it immediately. The normal functioning of the thermal alternation confirms the usefulness of an outline. Some switches are equipped of buttons of the compulsory return to an initial state manually.
Substitution of locks of security
For prevention of the short circuit and consumers' overloads of the electric power the separate outlines are protected by security locks. In the cars of Hyundai the security locks with contacts of the type of knife that corresponds to the last technical realizations are in use.
Before the substitution of a lock of security in the beginning certainly desconectam the corresponding consumer.
Hook up a covering of the block of locks of security to narrow screwdriver and withdraw it.
The lock of fused security is determined by the melted metal strip. The agreement of locks of security is shown in the interior of a covering of the block of locks of security.
There take away a lock of defective security the plastic tweezers that are in a covering of the block of locks of security.
Insert a new lock of security of the same value of expensive (current).
If fuses of lock of security again inserted by a little time, it checks the corresponding electric chain.
Do not substitute a lock of security in absolute with a wire or supporting applications similar ("defects") as because of him in the system of the electric equipment of the car there can be serious damages.
It is always recommended to have in the car the group of the locks of security of surplus of the value of different face. For his storage the appropriate place is supplied in the block of locks of security.
The current according to which the security lock is calculated puts itself in a reverse side of his case. Besides, the case is painted in the corresponding color by which is possible to determine the nominal current (it labels. 7.1).
Close a covering of the block of locks of security.

Alternation
To give from the electric current to some elements of the electric equipment of the alternations of the cars they are in use. The violation of the usefulness of the alternation leads to the refusal of the element served by him. In case of the suspicion in the bad any functioning of the alternation service stations check it or in the workshop of repairs of specialized car. The substitution of the failed alternation is made joined.
Installation of additional electric equipment
Perforating openings in a body of his edges it is necessary to withdraw agnails, the edges must be based and be painted. The shave that is formed when the perforation must be withdrawn of a body. During all the works about the electric equipment to avoid the short circuit the thread is necessary desconectar of pesos of the battery recarregável.

PREVENTION
In the moment of the stoppage of the information on battery recarregável of the memory of one unity of electronic control of the motor and the transmission, antiblockading the system and other electric devices, for example the radio-receiver and hours it is put out.

The threads established during the installation of the additional electric equipment whenever possible they must put themselves along wires braids and fix through collars of end and captures of rubber.
If one needs, it is necessary to fix besides that joining of a wire to avoid the emergence of the noise of an origin eletromagnética and friction for a strip, couplers of end or fastenings similar. It is necessary to think that between brake oil pipelines and rigidly it put electric wires there will be a distance not less than 10 mm, between the oil pipelines of brake and electric wires joined the motor or other elements of the car – not less than 25 mm.
During the installation of the check of additional electric equipment if the stock of creator's power is sufficient. If one needs, install the creator of the biggest power.
