Colored Russian-language diagrams of electrical equipment passenger car HYUNDAI ELANTRA IV produced since 2006. See older models. IN this car the negative ground electrical system has a voltage of 12 volts. Power for electrical equipment comes from lead acid battery which is recharged by a generator. When working on any vehicle electrical component, the negative battery cable must be disconnected to prevent a short circuit and/or fire.
Electrical parameters
The charging system includes a battery, a generator with a built-in regulator and control lamp chargers and cables. The car has an alternator with a six-diode rectifier. Alternating current, generated by the generator, is rectified by diodes and fed to the terminal "B" of the generator. In addition, the alternator charging voltage is regulated by the battery voltage control system.
At a high frequency of rotation of the generator rotor, when the generator voltage becomes greater than 13.6-14.6 V, the voltage regulator located in the brush holder is locked and the current does not pass through the field winding. The generator voltage drops, the regulator opens and again passes current through the excitation winding. The higher the frequency of rotation of the generator rotor, the longer the time of the closed state of the regulator, therefore, the more the voltage at the generator output decreases. The process of locking and unlocking the regulator occurs with high frequency, therefore, voltage fluctuations at the output of the generator are imperceptible and can practically be considered constant, maintained at the level of 13.6-14.6 V.

Most vehicle electrical power circuits are protected by fuses. Powerful current consumers are connected via relays. Fuses and relays are installed in mounting blocks, one of which is located in the passenger compartment and the other - in the engine compartment.
Most fuses are installed in mounting block inside the car (Fig. 10.1). It is located on the left side of the instrument panel under a plastic cover. The purpose of the fuses (their numbers are indicated on the block and figure) is given in Table. 10.1.
In addition, fuses, relays and fuse links are located in the mounting block installed in engine compartment on the left side in the direction of travel (Fig. 10.2, the mounting block cover is removed). In table. 10.2 indicates the purpose of these fuses, fusible links and relay, but specific model vehicle, some of the circuits shown in the tables may not be available.
The information is relevant for Hyundai Elantra 2006, 2007, 2008, 2009, 2010 models.

For guard electrical system fuses are used to protect the vehicle from failure as a result of electrical overload.
This vehicle has two fuse panels. One is located under the panel on the driver's side, the rest are in the engine compartment near the battery.
If any of your vehicle's lights, accessories, or controls are not working, check the appropriate circuit fuse. If the fuse is blown, the conductor inside it will be melted.
If the electrical system does not work, first check the fuse panel on the driver's side.
Always use a fuse of the same rating to replace a blown fuse. If the fuse blows again after the replacement, this indicates a malfunction of the electrical system components. Stop using the related vehicle system and consult an authorized HYUNDAI dealer.
Three types are used fuses: spade fuses for low currents and cartridge fuses for high currents.
CAREFULLY
- Fuse replacement
Always use a fuse of the same rating when replacing a fuse.
Installing a fuse with a large current rating may result in damage and fire.
Never install wire or aluminum foil in place of an appropriate fuse, even as a temporary measure. This may lead to severe damage wiring and possible fire.
ATTENTION
Do not use a screwdriver or any other metal object to remove fuses as this may cause short circuit and damage the electrical system.
1. Turn the ignition key and all other switches to the off position.
2.Open the fuse panel cover.
3. Remove the questionable fuse by pulling it up, vertically, at right angles to the fuse box. Use the puller found in the fuse panel cover in the engine compartment.
4.Check the removed fuse; if it is burned out, replace it with a new one.
5.Insert a new fuse with the same current rating and make sure it is secure in the clips.
If spare fuses are not available, use fuses with the same rating installed in the circuits of devices that are not essential to the operation of the vehicle, such as the cigarette lighter.
If the electrical components do not work with full fuses, check the fuse panel in the engine compartment. If the fuse is blown, it must be replaced.
Mode switch
Always keep the mode switch in the ON position.
If the switch is moved to the OFF position, some components may be reset and the transmitter (or electronic key).
ATTENTION
Do not change the state of the mode select switch
Replacing the fuse installed on the panel in the engine compartment
1. Turn the ignition key and all other switches to the off position.
2. Press the fuse panel cover and remove it.
3. Check the removed fuse. Replace if required. To replace or install a fuse, use the fuse pliers in the engine compartment fuse panel.
4. Insert a new fuse with the same current rating and make sure it is securely in the clips. If the clamps are loose, contact an authorized HYUNDAI dealer.
ATTENTION
After checking the soft fuse panel in the engine compartment, fasten its cover securely. Otherwise, failure of the electrical system may occur due to water entering the panel.
Main fuse
1. Disconnect the cable from the negative battery terminal.
2. Loosen the nuts shown in the figure above.
3. Always use a fuse of the same rating to replace a blown fuse.
4. Installation is carried out in the reverse order of disassembly.
Multifuse
If the main fuse is blown, it should be replaced. Replacement is performed in the following order:
1.Remove the fuse panel located on the right side in the engine compartment.
2. Loosen the nuts shown in the figure above.
3. Always use a fuse of the same rating to replace a blown fuse.
4. Installation is carried out in the reverse order of disassembly.
✽
FOR YOUR INFORMATION
If the main fuse is blown, contact an authorized HYUNDAI dealer.
Description of the fuse and relay panel
Under the cover of the fuse and relay panel there is a plate with the names of the fuses/relays and their rated currents.
