General information
The negative ground electrical system has an operating voltage of 12 volts. Power for the electrical system comes from a lead-acid battery that is recharged by a generator.
It should be noted that when working with any element of the electrical equipment of the car, the wire of the negative terminal of the battery must be disconnected to prevent a short circuit and / or fire.
At regular intervals, check the location and fastening of the wires, make sure that the wires do not rub against other elements. If you find that any of the wires are rubbing against other elements, move the wires to the side and secure them so that this does not happen again.
Precautionary measures
It is forbidden to change the polarity of the power supply of various devices and devices of electrical equipment in order to avoid failure of semiconductor devices.
Do not disconnect or connect the battery, gauges, or any wires while the engine is running.
It is forbidden to check the serviceability of the generator by shorting the power output to ground.
Diagnostics of malfunctions of onboard electrical equipment
A typical electrical circuit may include a main electrical element, various switches, relays, electric motors, fuses, fuses or circuit breakers related to this element, as well as wiring and connectors used to connect the main element to the battery and «weight» body. To facilitate troubleshooting of electrical circuits, the manual provides circuit diagrams and wiring diagrams.
Before you start troubleshooting any electrical circuit, carefully study the corresponding diagram in order to understand its functional purpose as clearly as possible. The circle of troubleshooting is usually narrowed by gradually identifying and eliminating normally functioning elements of the same circuit. With the simultaneous failure of several elements or circuits at once, the most likely cause of the failure is a blown fuse or a ground fault (different circuits in many cases can be closed to one fuse or ground terminal).
Electrical equipment failures are often due to the simplest causes, such as corroded connector pins, blown fuses, blown fuses, or damaged relays. Perform a visual inspection of the condition of all fuses, wiring, and circuit connectors before proceeding to more specific component health checks.
If using diagnostic tools for troubleshooting, carefully plan (in accordance with the attached wiring diagrams), at which points of the circuit and in what sequence the device should be connected in order to most effectively detect a malfunction.
Basic diagnostic tools include an electrical circuit tester or voltmeter (a 12-volt test lamp with a set of connecting wires can also be used), open circuit indicator (probe), including a lamp, its own power supply and a set of connecting wires. In addition, you should always have a set of wires in the car for starting the engine from an external source (battery of another car), equipped with clip type «crocodile» and preferably an electrical circuit breaker, which can be used to bypass and connect various electrical equipment in circuit diagnostics. As already mentioned, before proceeding to check the circuit using diagnostic equipment, determine the connection points from the diagrams.
Checks for the presence of supply voltage are carried out in the event of an electrical circuit failure. Connect one of the circuit tester leads to either the negative battery terminal or a well grounded point on the vehicle body. Connect the other tester lead to the connector pin on the circuit under test, preferably closest to the battery or fuse. If the tester's control lamp lights up, there is supply voltage on this section of the circuit, which confirms the health of the circuit between this point in the circuit and the battery. Proceeding in the same way, examine the rest of the chain. Detection of a power failure indicates the presence of a malfunction between this point in the circuit and the last one previously checked (where was the supply voltage). In most cases, the cause of the failure is loosening of the connectors and damage to the contacts themselves (oxidation).
Attention! Please note that some on-board electrical circuits are only powered when the ignition key is in the «ACC» (parking) or «RUN» (movement).
Search for a short circuit. One method for finding a short circuit is to remove the fuse and connect a probe lamp or voltmeter instead. There should be no voltage in the circuit. Pull the wiring while watching the probe lamp. If the lamp starts flashing - somewhere in this wiring harness there is a short to «mass», possibly caused by chafing of wire insulation. A similar test can be carried out for each of the components of the electrical circuit by turning on the appropriate switches.
Checking the health of the grounding. This test is carried out to determine the reliability of the grounding of a circuit element. Disconnect the battery and connect one of the wires of the probe lamp, which has an independent power source, to a known well-grounded point. Connect the other lamp wire to the wire harness or connector pin you are testing. If the lamp lights up, ground is OK (and vice versa).
An continuity test is performed to detect open circuits. After disconnecting power to the circuit, test it with a self-powered test lamp. Connect the probe leads to both ends of the circuit. If the test lamp lights up, there is no open in the circuit. If the lamp does not light up, then this indicates an open circuit in the circuit. Similarly, you can check the health of the switch by connecting a probe to its contacts. When the switch is turned to position «On» the probe lamp should light up.
Break location. When diagnosing a suspect for an open section of an electrical circuit, visually detecting the cause of a malfunction turns out to be quite difficult, since inspecting the terminals for corrosion or a violation of the quality of their contacts is difficult due to limited access to them (normally the terminals are covered by the connector housing). A sharp twitch of the connector housing on the sensor or its wiring harness in many cases leads to the restoration of contact. Do not forget about this when trying to localize the cause of the suspected failure for an open circuit. Intermittent failures may be due to oxidation of the terminals or a deterioration in the quality of the contacts.
Diagnosing faults in electrical circuits is not a difficult task, provided it is clear that the electric current is supplied to all consumers (lamp, electric motor, etc.) from the battery through wires through switches, relays, fuses, fuses, and then returns to the battery through «mass» car body. Any problems associated with electrical equipment failure can be caused by the loss of electrical current from the battery to them or the return of current to the battery.
Wires, fuses and relays
Protection of the vehicle's electrical circuits from short circuits is ensured by the use of fuses, circuit breakers and fuse links. A blown fuse is easy to distinguish from a good one by examining its transparent plastic case. Check the fuse carefully. If the fuse looks normal on the outside, but it is suspected to be defective, check for continuity between the knife-type contacts protruding from its body.
When replacing fuses, make sure that the value of the new fuse matches the value of the old fuse. Fuses designed for different amperages may look the same on the outside, so special attention should be paid to the marking. Replacing a blown fuse with one designed for a smaller, and especially a large, current strength is undesirable. Every electrical circuit needs a different degree of protection. Make sure that the marking on the fuse body corresponds to the current strength for which the fuse is designed
corresponding chain. If the replaced fuse blows immediately, it is unwise to continue replacing it. First of all, you should determine and eliminate the cause of its burnout. In most cases, this turns out to be a short circuit in the electrical circuit caused by a break or damage to the wire insulation.
Fusible links
Protection of some electrical circuits is carried out by including fusible links in them. Typically, inserts are used to protect circuits that are not equipped with fuses, such as the ignition system circuit.
Fuses are similar to fuses in that their failure (reflow) easily determined visually.
To replace the fuse, disconnect the wire from the negative battery terminal. Remove the burnt insert and install a new one in its place. Before replacing an insert, be sure to try to determine the cause of the overload that caused the failure of the insert.
Circuit breakers (thermal relays)
Thermal relays are used to protect elements such as power windows, door locks and electric corrector. Some of the circuit breakers are installed in the mounting block. The return of thermal relays to their original state on some models is carried out automatically, i.e. when an overload occurs in the circuit, the thermal relay instantly opens, then after cooling it returns to its original state. If the circuit does not return to working position, it should be checked immediately. The normal functioning of the thermal relay confirms the health of the circuit. Some of the breakers are equipped with push buttons for manual resetting.
Replacing fuses
To prevent short circuits and overloads of electricity consumers, individual circuits are protected by fuses. Hyundai vehicles use blade type fuses that are state of the art.
Before replacing a fuse, be sure to switch off the relevant consumer first.
Pry off the fuse box cover with a narrow screwdriver and remove it.
A blown fuse is identified by a molten metal strip. The location of the fuses is shown on the inside of the fuse box cover.
Remove the defective fuse with the plastic tweezers located in the cover of the fuse box.
Insert a new fuse of the same rating (current strength).
If a newly inserted fuse blows after a short time, check the related electrical circuit.
Never replace the fuse with wire or similar aids («bugs»), as this could cause serious damage to the vehicle's electrical system.
It is recommended that you always have a set of spare fuses of different ratings in your car. A suitable place is provided for their storage in the fuse box.
The current strength for which the fuse is designed is printed on the back of its case. In addition, the housing is painted in the appropriate color, which can be used to determine the rated current (tab. 7.1).
Close the fuse box cover.

Relay
Relays are used to supply electric current to some elements of the vehicle's electrical equipment. Failure of the relay leads to failure of the element served by it. If any of the relays is suspected to be defective, have it checked by a service station or specialist workshop. Replacing a failed relay is carried out as an assembly.
Installation of additional electrical equipment
When drilling holes in the body, burrs must be removed from their edges, the edges themselves must be primed and painted. Chips formed during drilling should be removed from the body. During all work on electrical equipment, it is imperative to disconnect the cable in order to avoid a short circuit «masses» from the battery.
Attention! Disconnecting the battery erases information from the engine and transmission ECM, anti-lock braking system, and other electrical devices such as the radio and clock.
Cables installed during the installation of additional electrical equipment, if possible, should be laid along the wire harnesses and fastened with cable ties and rubber bushings.
If required, the wires must be additionally fixed with adhesive tape to avoid electromagnetic noise and friction with tape, cable ties or similar fasteners. It should be noted that there must be a distance of at least 10 mm between the brake pipelines and rigidly laid electrical wires, and at least 25 mm between the brake pipelines and electrical wires connected to the engine or other elements of the vehicle.
When installing additional electrical equipment, check that the generator power reserve is sufficient. If required, install a larger generator.
