Renault Logan starter relay where it is located - we explain the essence

4903

A common problem that sooner or later faces the owner of any car is starter failure. In this case, the car engine does not start or even turn over. If your Renault Logan does not want to turn the starter, then it’s time to repair it. This is exactly the topic that will be discussed in our article.

Diagnosis and causes

Turn the key and try to start the engine, if the engine does not start and the starter does not turn, and instead of the usual sound you only hear it clicking, so you can say that the rotor brushes have come to an “end”.

To give an explanation of why the relay clicks and the engine does not start, you need to understand the scheme of its operation. At the moment when you turn the key to the engine start position, a special block called a retractor makes contact on the rotor shaft brushes, thereby the starter spins the engine flywheel.

When this mechanism or relay does not work, it urgently needs to be removed and repaired, otherwise extremely serious consequences can occur, including fire.

This is the principle behind the work of the starter and its relay. When the brushes are worn out, the relay tries to operate and make contact on the shaft; if it clicks, the brushes are worn out, and it’s time to change them.

To the question of where the starter and its relay are located, we will answer unequivocally - near the rear flywheel of the engine. This arrangement is typical for all engines, including Renault Logan 1.4.

If the starting device idles and the engine does not start, then you need to change the bendix, and possibly the fork. This work can be done without any problems with your own hands, but first remove the on-board voltage.

When the relay clicks, you need to understand that the problem is definitely not with it, it works.

Repairing this unit, as well as replacing the bendix, can easily be done with your own hands, but to do this you will need to remove the entire unit.

Renault Logan fuses and relays, electrical diagrams

Renault Logan is considered an inexpensive, affordable and reliable car. It’s not for nothing that many people use these cars to work as taxis. At a relatively low cost, this model is quite reliable for Russian roads.

But in any car, especially after long trips and a certain number of kilometers, certain problems begin to appear related to electrical appliances, contacts, and wiring.

This is especially noticeable on older cars that have served more than one owner.

To quickly find and fix electrical faults in Logan, you need to know where the Renault Logan fuses and relays are located, how the circuits and power supply circuits of the devices are made. Mounting blocks and ways to solve electrical problems will be discussed in this article.

Causes of cigarette lighter failure

The device may stop working due to various factors. The main reasons for a malfunction of the Duster cigarette lighter are improper operation of the device or great age, or a blown fuse. Common breakdowns.

1. A loose nest. Frequently connecting foreign electrical devices with a non-standard plug to the connector can bend the fixing antennae, causing the contact to disappear. Repairing the Duster cigarette lighter in this case is simple - you need to remove it from the socket and then bend the clamps inside the socket. To avoid short circuit, you must remove the fuse before this procedure.
2. Oxidized contacts or plaque. Age-related disease. It may also appear after liquid gets on the legs. Because of this, the integrity of the circuit is compromised, and in extreme situations there is a risk of the fuse tripping and a short circuit. Repairing the cigarette lighter is simple - just rub the contact areas with sandpaper or a file, removing traces of foreign substances.
3. Burnt fuse. The maximum current strength of this segment of the electrical circuit is 15 amperes. The maximum permissible power of connected devices is 180 Watt (p=I*A, 180 Watt = 12 volts*15 amperes). Due to a short circuit or exceeding the permissible value, this parameter may go out of range. To protect the wiring insulation from melting, the fuse on the Duster fails. The repair consists of getting to the mounting block. Next, replace the blown fuse.
4. "Shorty." If the new fuse blows again, then it is obvious that there is a short circuit in the network. Turn off the ignition and then measure the battery voltage. Turn on the ignition and take measurements again. A difference of more than 0.5 volts is unacceptable - this is evidence of a short circuit and a tripped fuse. You should arm yourself with a multitester and test all the wires going to the device.
5. Fallen cables. Due to age or intensive use, the wires on the Duster cigarette lighter may fray or fall off at the soldering points. The fuse trips. You should test all cords for resistance, and also inspect them to see if there are any creases, exposed wiring, or broken areas. Broken cords must be replaced with new ones, and missing soldering points must be soldered using a soldering iron and tin.
6. Burnt-out filament. After prolonged exposure to temperature, the spiral inside the rod may burn out, causing the device to stop functioning. It will be necessary to remove the Renault Duster cigarette lighter, and then replace it with a new spare part.
7. Broken backlight lamp. The light bulb that guarantees the operation of the filter may burn out due to age or constant shaking. To replace it, you will need to remove the cigarette lighter, dismantle the filter and change the lamp.

Thus, it can be seen that all electrical circuits pass through the fuse box under the hood of the Renault Duster, and only after that, through the block in the car’s interior. If a fuse blows, it must be replaced with the same one so that the markings match.

Renault Logan fuse diagram

The electrical circuit according to which the Renault Logan provides power to the cigarette lighter unit is very primitive. The standard source sends voltage to the fuse (10A), which is located inside the mounting module.

This fuse box is located in the cabin, or more precisely, above the Renault Logan hood release handle. Wires connect two objects: the mounting block itself and the corresponding socket on the console.

In this article we will tell you where a very important element is located - the cigarette lighter fuse, as well as other fuses and relays, as well as a fuse diagram for a Renault Logan car.

If a malfunction occurs, you should first make sure that the corresponding fuses are intact. Its markings are red and have the symbols “F38”. It is important to remember that there is no cigarette lighter symbol on the surface of the mounting block cover. The cigarette lighter fuse is powered by the audio system.

This forces you to navigate precisely by its designation. Therefore, you can easily find where the very important element, the cigarette lighter fuse, is located, since due to the numerous gadgets connected to it (laptops, smartphones, etc.), these fuses fail more often than others, not only on Renault Logan.

Among the most common causes of block burnout is the fact that a large number of simultaneously functioning energy consumers are connected to the Renault Logan on-board network. If any of the devices consumes a current whose value exceeds 10A, then subsequent burnout is guaranteed.

Here among the leaders is the electric pump. To prevent damage to the unit, the procedure for inflating the wheels should be performed with the audio system turned off, since the radio and the pump are powered through the same circuit.

Before connecting the hose to the nipple, pause, allowing the pump to run idle for a short time.

Another important cause of failure may be the incompatibility of the size of the pantograph plug with the power socket. Loose contact causes increased heating of the terminals. Upon reaching a specific temperature value, the terminals begin to melt and cause a short circuit. In such a situation, replacing a single fuse cannot be done. The entire block has to be replaced.

Preventive actions

If you don't want to constantly stock up on tons of fuse sets, you should implement a strategy to counteract their frequent failures.

1. The first and most common method is to use fuses on an analogue with a higher power. Experts recommend using devices with a power of 15A. The likelihood of burnout is minimized, and damage to the on-board network does not occur.
2. The second measure will be the correct selection of the device. The packaging containers of the most diverse products indicate their power consumption. It’s great if they have their own element. To prevent burnout, carefully read the characteristics of the device you intend to purchase. This is a simpler action compared to “uprooting” the fuse from its socket.
3. Thirdly, the plug must be connected correctly. Due to its inconsistency with the design features of the nest, the above problems arise.

To ensure correct connection, the location of the contacts must be horizontal, but not vertical (that is, on the sides, but not at the top and bottom). This action will prevent melting of the terminals in the Renault Logan car.

If a malfunction does occur and the fuses become unusable, then the only solution is replacement. The procedure is quite simple. In order to remove the fuses from the mounting socket, it will be enough to pry them with a flat-profile screwdriver.

About security measures

The fuse box is designed to prevent a fire hazard that occurs due to a short circuit in the electrical network of a Renault Logan car. Even the presence of a block does not allow you to be completely insured against trouble.

Removal and replacement process

To replace failed parts, you will need plastic tweezers, included with the car, and a screwdriver with a narrow flat blade.

Under the hood

The procedure is as follows:

1. Turn off the ignition and remove the key from the lock,
2. Take puller tweezers.
3. Open the driver's door.
4. Remove the cover from the interior unit.
5. Open the hood.
6. Remove the mounting block cover by unlatching the latches on the desired side (for machines assembled before 05/17/2005) or by sliding the latches (for machines assembled after 05/17/2005).
7. Using tweezers or your hand, pull out the failed relay or fuse. If this cannot be done, you can use a screwdriver by inserting its tip into the slot on the fuse and pulling up.
8. Eliminate the cause of the fuse-link burnout or relay failure.
9. Install a new fuse or relay.
10. Reinstall the removed parts in their original locations.

The fuses and relays of the 2nd generation Renault Logan car perform one of the main tasks - instead of burning out the electrical circuit, they burn out themselves.

Only the relays also switch high currents in the protective casing of the switchboard.

These elements are located in two places in the second generation Renault Logan - in the power unit compartment and in the vehicle interior.

Replacing the fuse box

This procedure is required when the fuses begin to blow. This means that their service life has expired, or the problem is related to contamination, moisture and other factors that lead to rapid wear of the elements of the 2nd generation Renault Logan car.

To replace, the first step is to turn off the powertrain and remove both terminals from the battery. Then remove the fuse box cover. Unscrew the bolts and remove the spare part.

After dismantling, install a new unit.

Important information: if you are not confident in your abilities, it is recommended to contact a service center to repair the damage. Experienced mechanics will carry out the procedure quickly and at an affordable cost.

Cigarette lighter repair

A malfunctioning device must be restored. When removing the cigarette lighter, perform the following steps:

1. Inspect areas that are frequently damaged. They start by checking the contacts for the presence of an oxide film. If the driver finds traces of rust, it is recommended to treat the elements with sandpaper or an anti-corrosion agent. The contacts are bent to ensure firm fixation in the socket.
2. Inspect the fuse and wiring, which is located on the back of the unit. To check, use a multimeter, which is switched to resistance determination mode. All wires going to the block are ringing. If there is no contact, look for the break point. The conductors are soldered with a soldering iron.
3. They assemble the device, evaluate its performance by connecting different devices.

Replacement and connection

Before installing a new part, you need to remove the old one using the above method. After this, place the device in the seat and connect the wire block. If necessary, you can change the plastic holders that secure the cigarette lighter in the center console. Install the block, close the latches of the lighting fixture. Solder the black wire to the car cigarette lighter cylinder. The reverse end of the cable is brought out to the body. The red wire is connected to the heating element. The yellow cable is connected to the backlight. Both wires lead to the battery.

Fuel pump diagnostics

In order not to make a mistake when buying a new part, you should be sure that it is the fuel pump that is not working. To do this, you will have to carry out a number of diagnostic operations. So let's get started:

1. The first diagnostic operation will be to simply turn on the ignition switch. If you turn the key to position No. 2, the fuel pump will create a certain sound that will be heard. If he didn’t appear, then that’s definitely the reason.
2. The next step is to examine fuses and relays.
   Examine the fuse (F02 (5 A)), which is responsible for the operation of the fuel pump, and determine its functionality. Change if necessary. Location of fuses in the main unit
3. Now you should diagnose the relay. To do this, you need to turn the ignition key several times, if it clicks, then everything is fine. It will not be possible to check the relay using diagnostic programs that work through the connector.
4. If all of the above elements are intact, then the fuel pump is “dead” and must be replaced.

Prevention options

In order not to constantly purchase a large number of fuses, you need to apply preventive measures.

1. The most common way to avoid frequent failure of fuses is to replace them with a more powerful element. Experts recommend installing the device at at least 15 amperes. In this case, the likelihood of problems occurring and fuses blowing is reduced significantly.
2. Secondly, you need to carefully select devices, since the electrical power is indicated on the packaging of DVRs, car radios and other products used in cars. To avoid blowing fuses, you need to carefully read their technical characteristics and only then connect them to the car’s electrical network.
3. The third condition is that it is recommended to connect the plug correctly. Since due to a mismatch between the standards of the plug and socket of the device, certain problems may arise. The plug is connected correctly if the contacts are in a horizontal position, i.e. on the sides (not below and not above!). This arrangement will avoid burnout and melting of the terminals.

But if a problem does arise and the element burns out, then it will have to be replaced with a new one. This procedure is extremely simple; in Renault Logan you can get it out by prying it off with a thin flat-head screwdriver.

Brake light faults

View of the additional brake light from inside the car

If you decide to start or continue driving a car when the brake lights are faulty, this means exposing not only yourself, but also all other road users to danger. Therefore, lamps should be periodically monitored and maintained.

Among the problems, the most common cases are:

1. During braking, the brake light does not work on one side.
2. When braking, the brake lights on both sides do not work.
3. Additional signal light does not work

Diagnostic and repair methods

Since the functioning and performance of these outdoor lighting elements directly depends on the performance of the vehicle’s electrical network, it is necessary to pay close attention to its condition. If all the brake lights on your car stop working at once, the reason for this is most often the failure of fuse F3 (for the passage of current with a force of no more than 20A) located in the Renault Logan interior fuse box

If all the brake lights on your car stop working at once, the reason for this is most often the failure of fuse F3 (for the passage of a current with a force of no more than 20A) located in the fuse box of the Renault Logan interior.

The location of the fuse we need is marked with a red marker.

This element is part of the direct power supply circuit to the brake lights. You can check the serviceability of the circuit using a known good fuse or using a tester (multimeter). If such manipulations do not bring the desired result, and the lights still do not work, then the search for the fault must be continued. The next step in the repair will be to check the wiring for evidence of breakage or chafing of the wire in the circuit.

Next, an element that can also cause a malfunction is the brake lamp switch on Renault Logan, which is installed on the bracket with the pedals. For more effective diagnostics, it is best to remove it from its seat. This work is carried out in the following order:

1. Since the circuit of this sensor is constantly energized, you should disconnect the negative terminal from the battery.
2. Next, remove the connector with wires.
3. In order to pull it out from its place of fixation, you need to turn the sensor body 90 degrees and slowly pull it towards you until it is completely dismantled.

To check the sensor, you can use a tester and measure its resistance, or connect a known-good sensor. Checking the device with a tester is very easy; we connect the tester wires to the sensor connectors, and use our hands to operate on the protruding rod. A working device will thus show its functionality, but a broken one must be replaced.

The next step is to check that the mains voltage is reaching the working sensor. We connect the battery back to the network and use the equipment to check the voltage in the sensor terminals. If the result is positive, we put everything back together in reverse order and proceed to direct diagnosis and replacement of the brake light bulbs.

About security measures

The fuse box is designed to prevent a fire hazard that occurs due to a short circuit in the electrical network of a Renault Logan car. Even the presence of a block does not allow you to be completely insured against trouble.

Among the most common factors that cause a fire is the failure of the cigarette lighter due to negligence when handling it. To prevent such an emergency you will need:

• carefully familiarize yourself with the features of the instructions for the connected devices (the most dangerous are on-board voltage converters to 220V);
• purchase only high-quality fuses and relays;
• choose the right plug, which will ensure a tight fit inside the power socket and prevent spontaneous falling out under conditions of strong shaking;
• the cable supplying the device should not be subject to tension, which will allow the plug to be held in the socket;
• It is strongly recommended not to leave devices turned on unattended in cases where the cigarette lighter socket in the Renault Logan is not de-energized when the ignition is turned off.

About the features of the system design

The design of the fuel supply system to the Renault Logan engine implies the presence of several components through which the fuel-air mixture under pressure enters the combustion chambers of the cylinders. The main elements of this system are:

• gas tank;
• main fuel line;
• fuel rail;
• return line;
• nozzles;
• pressure regulator;
• fuel gasoline pump;
• level sensor and filter.

Sometimes the fuel pump needs to be replaced. The functioning of the system under consideration is subordinated to an on-board computer, which, in real time, based on signals from various sensors, adjusts the operation in order to ensure that the mixture is supplied to the combustion chambers with an optimal ratio of fuel and air.

Key-dop

1. When the ignition key is turned to the 2nd position, the fuel pump relay is turned on, which operates for several seconds, providing the required pressure in the fuel rail. The engine can then be started. This is the normal operating mode of the system.
2. When the Renault Logan engine starts, the relay is activated again, ensuring that the pump operates continuously throughout the entire engine operation. Thanks to this, fuel is supplied to the ramp continuously through the fuel pump. In it, the regulator ensures that constant fuel pressure is maintained, eliminating the formation of excess (it returns to the tank via the return line).
3. If interruptions occur in the operation of the motor, the first diagnostic measure will be to check the integrity of the pump fuse and relay. And if a breakdown is detected, the fuel pump needs to be replaced.
