Motorcycle cigarette lighter, application and how to install the cigarette lighter

Any car cigarette lighter, including the VAZ-2110, was initially designed only for use for its intended purpose. However, over time, “necessary” car gadgets began to appear that needed to be connected somewhere. Since the factory did not provide for the installation of a 12-volt outlet in the car, the cigarette lighter is the power source for vacuum cleaners, refrigerators, televisions, video recorders, compressors and phone chargers. This does not benefit him and quite often he breaks down at best.

At worst, a connected gadget left unattended can lead to a fire.

Cigarette lighter diagram for VAZ-2110

Troubleshooting

In any case, the breakdown can be either mechanical or electrical in nature.

Mechanical damage to the cigarette lighter socket is quite rare, although it can be damaged by a poor-quality or incorrectly selected plug. Based on the diagram shown above, the cigarette lighter is standardly connected to one power output from the mounting block with the glove compartment lighting lamp.

This is the first clue - if the cigarette lighter does not work, but the glove compartment lamp is on, the problem is either in the cigarette lighter mechanism itself ( spiral, contacts, resistor ), or in a broken wire in the area from the power terminal to terminal 25 of the mounting block.

Circuit breakers

Cigarette lighter fuse 25A, marked with arrow

However, fuses are the first to come under suspicion. If the cigarette lighter does not warm up within 20 seconds and the glove compartment lamp does not light up, most likely the 25A fuse F18 . It is located in the mounting block to the left of the driver.

There is another 15 A , which is connected to the cigarette lighter circuit. There is a socket on it and this may also be the cause of the malfunction. This fuse is marked with the symbols F6. In some modifications of the VAZ-2110, depending on the year of manufacture, both the cigarette lighter and the heater motor are connected to one circuit of fuse F18.

Therefore, checking the integrity of the fuse in these cases is also simple - the motor does not spin, which means the fuse has burned out.

Why do fuses burn?

Each consumer of electricity on board the car is designed for a certain power and a certain current consumption, measured in Amperes . If we plug in a video recorder, navigator, or charge a phone into the cigarette lighter through a splitter, it is not surprising that the fuse simply fails. Saving our wiring from overheating and short circuit, it melts, breaking the circuit.

That is why it is important to take into account the current consumption of additional devices - a compressor, a refrigerator and other architectural excesses. Both the power and the current consumed by the device must be indicated on the body of the device. It is highly undesirable to include powerful devices in the cigarette lighter circuit, as well as use splitters and plugs of dubious quality.

This could ultimately lead to a fire in the wiring.

Melted cigarette lighter wires.

It is not for nothing that in many imported cars the manufacturer has completely abandoned the cigarette lighter, and instead installs 12-volt sockets in the front part of the cabin (as is done in the same second-generation Ford Focus).

Checking the wiring

If the fuse is intact and we haven’t plugged any vacuum cleaners into the cigarette lighter, most likely the problem is in the contacts or wiring.

To check the cigarette lighter power wiring, we need to remove the center console by unscrewing several screws. Most often, the contact disappears in the contact chips, which are located to the left of the passenger behind the console casing:

Unscrew the console cover.

Remove the cover from the passenger seat.

We take out and check the blocks with wires.

Check the cigarette lighter for a break or short circuit.

Cigarette lighter inspection

Lastly, we inspect the cigarette lighter itself.

It rarely fails, but if it does, we won’t disassemble it, it’s not the king’s business. We buy a new one.

New cigarette lighter assembly.

Its price is about 400-500 rubles , and the catalog number is 2123-3725010 or 2123-3725/111.3725 , the manufacturer is usually SOTE.

Cigarette lighter. What it can be used for and how it works

Why can you charge devices with different power levels using a cigarette lighter?

The cigarette lighter is one of the few car components that has had the same design throughout almost the entire period of its existence.
Therefore, cigarette lighters installed both on old domestic car models and on the most modern cars have an identical design. When cigarette lighters were first invented, they had only one function. Today, this device has many more functions and they are not similar to those that were previously. For example, a cigarette lighter today can serve as a connector to charge a device. Sometimes it is even used to start a car. The device remains the same simple, and the design is quite perfect. In some modern car models, for convenience, several such cigarette lighters are installed, as a result of which all passengers, including those sitting in the back seat, can use the connectors.

Main purpose

When the cigarette lighter was first invented and began to be installed in cars, it was assumed that it would be used exclusively for lighting cigarettes. That is why the device has such a name.

But motorists used it for these purposes very rarely. Out of habit, they used lighters or matches. Those who do not smoke did not use this device at all.

The time came when car manufacturers wanted to avoid using the cigarette lighter in the production of new car models due to its uselessness.

Cigarette lighter VAZ 2110

If your car's cigarette lighter socket is not working, you will need to replace it. In a VAZ 2110 car, replacing the cigarette lighter is not too painstaking work. But before that, it will be necessary to test it, that is, check whether it really does not work. Replacing the cigarette lighter on a VAZ 2110 can be easily done with your own hands.

Additional cigarette lighter in the trunk

In the trunk
It would be convenient if there was a cigarette lighter socket in the trunk; you can connect a variety of devices to it, which are difficult to do without on vacation, on the road, and in many other situations.

So, if there is such a socket in the trunk, the car owner has the opportunity to quickly connect an electric pump to inflate car tires, without which it is impossible to travel long distances.

It is equally convenient to use the cigarette lighter socket located in the luggage compartment to connect a vacuum cleaner, without which it is quite difficult to clean up the interior of the car.

Cigarette lighter socket
Installing a cigarette lighter socket in the trunk does not take much time and is carried out in the same way as installing a cigarette lighter in the passenger compartment.

Thus, equipping the interior of your car with several cigarette lighter sockets will allow you to connect all the necessary car equipment that you are used to using. Now the navigator will show you the route while your phone is charging, and the DVR records everything that happens along the way on a memory card.

Check and replacement

Replacing the cigarette lighter in a VAZ 2110

Turn on the ignition.
Insert the cigarette lighter into the socket.
Wait 10-15 seconds.
Take it out.

Note: if it has not warmed up during this time, then it really does not work.

Replacing the cigarette lighter for VAZ 2110

Of course, you can go to a dealership to have it replaced by a qualified automotive technician, but you can also replace and install it yourself to save money. Replacement instructions:

First you need to find a fuse (see VAZ 2110: how to replace fuses) that protects the cigarette lighter from spontaneous combustion. To easily remove it, you need to break the chain.

Note: Removing the fuse is important because if the wiring located at the top is tangled, it can cause damage to other electrical things in the car. The wiring will simply burn out and will need to be replaced. Before you begin replacing the fuse that protects against spontaneous combustion, you should read the machine's user manual.

Now you have to remove the faulty device. To do this, you need to take a flat screwdriver and insert it into the slot (the cigarette is placed there). The screwdriver needs to be turned several times.

Note: this should be done extremely carefully so as not to tear out the socket, since in this case the other cigarette lighter is unlikely to function normally.

The process of replacing the cigarette lighter of a VAZ 2110

If this method does not work, you will have to try to release the metal clips that hold it in place.

Note: these clamps are very easy to unfold, but there is no need to rush. It is better to do the work longer, but with better quality.

VAZ 2110 how to remove the cigarette lighter

After removing it, you will have access to two wires with spade connectors. You need to remove both wires so that they are completely disconnected.

Note: if they are not turned off, they may short out and catch fire during operation.

Now it will be much easier to replace this device. It is necessary to connect the spade-shaped connectors to the peaks located on the back of the device. You need to insert the black into black and white into white wires accordingly.

Note: otherwise the circuit will not be closed and the device will not work.

After connecting the wires, you can install it in place by pushing it into the hole provided for this.

Note: Press it lightly and then twist it clockwise until it is secured by the two metal clips. He must be motionless.

Now all that's left is to replace the fuse in the fuse box (if it doesn't work) or install the old one.

Note: this is a prerequisite, since without it a short circuit is possible.

What is a car cigarette lighter and how to connect it

"Cigarette lighter", in automotive slang, can mean two things:

1) Internal - technological connector(s) in the vehicle interior;

2) External - wires for starting the car using another car, starting station, spare (other) battery;

What is a car cigarette lighter and how to connect it

They are completely different in purpose and in how to properly connect the cigarette lighter, and the design of a car cigarette lighter can be different. Therefore, we will deal with each type point by point, how to connect the cigarette lighter, what is the standard cigarette lighter connection diagram, and so on.

Operating principle

An interesting device, this same cigarette lighter. Cars have been equipped with this option since time immemorial, when the era of automobile manufacturing was just beginning. In those days, only rich and wealthy people could afford a car, and since the bulk of them were smokers, not only cigarettes, but also cigars, the manufacturer had a need to install a cigarette lighter for the car as an option. Moreover, the size of the cigarette lighter for a car was developed specifically for lighting cigars, and this is how it has survived to this day.

The cigarette lighter consists of a connector and the heating element itself, the connection diagram for the cigarette lighter is simple, the connector is connected to the vehicle's on-board network (12 V) through a fuse. When the head of the cigarette lighter is inserted into the connector, the heating element becomes hot, which allows you to light a cigar or cigarette.

If you pull out the heater, you get a fairly powerful and reliable connector into which you can connect various consumers. Manufacturers of various automotive equipment and additional equipment were quick to take advantage of this; the following can be connected to the cigarette lighter socket:

— televisions;

— refrigerators;

— ionizers;

— compressors and any heater for the car from the cigarette lighter;

— players and modulators;

— various lighting and chargers;

— DVRs, vacuum cleaners, water pumps and pumps, and much more;

At the beginning of the 21st century, a car cigarette lighter was the source of one incident. According to the program to combat tobacco addiction, some manufacturers stopped installing cigarette lighters and ashtrays in their cars, thereby causing a protest from motorists due to the inability to use their favorite devices. Automakers had to put the connector back in place, but they had to say goodbye to the heater and ashtrays.

Indispensable and useful devices

If you received a car with a missing or non-working cigarette lighter, this can be easily fixed. How much does a cigarette lighter for a car cost and how to connect the cigarette lighter - these are the most difficult questions in this matter. After purchasing, you need to decide on the location of the device. Then you need to find the main power cable in the cabin and connect the plus of the cigarette lighter to it, the minus to the body and the third wire, this is the “dimension” (light, connects to any clearance wire). The cigarette lighter connection diagram is very simple.

We connect the cigarette lighter

If you have many consumers connected to the cigarette lighter, you can use a splitter. Even a child can cope with such a problem as connecting a cigarette lighter splitter. We simply plug the cord into the cigarette lighter socket and get full, additional three sockets (no longer recommended).

How to connect the DVR to the cigarette lighter:

Here it all depends on the model of the DVR; if there is a cigarette lighter connector on the power cord, then the procedure is simple: insert it into the socket and that’s it. If you need to connect the power to the DVR, you can either purchase an additional cigarette lighter connector or select a different connection point.

or radio:

Modern cars already have a car audio power line. But in older models (especially domestic ones), there is no such wiring. It makes no sense to occupy the cigarette lighter socket with a stationary radio, but you even need to use the line and wiring of the cigarette lighter. To do this, after installing the radio, you need to remove the cigarette lighter connector and, observing the polarity, connect the radio wiring.

An indispensable device is the car cigarette lighter pump. This device really makes life easier for car enthusiasts. The problem with a flat or underinflated tire can be solved in a matter of minutes by connecting the compressor to the cigarette lighter socket.

Also one of the very convenient devices is a car heater from the cigarette lighter. As a rule, this can be heated seats or a fan heater to quickly defrost and warm the windshield or other windshields. Any of these devices is plugged into the cigarette lighter connector for the required operating time, and can be easily removed during the warm season.

There are many rumors that there is supposedly some kind of “mythical” flash drive for the car in the cigarette lighter. We are most likely talking about a regular FM modulator. The principle of its operation is that you can listen to music in MP3 format on a regular radio. It looks like this: Music (MP3) is recorded onto a flash drive, then inserted into the modulator, and the modulator into the cigarette lighter socket. After turning it on, you need to search for radio stations and find the modulator wave, that is, the music will go through the radio.

Terms of use

Since all devices connected to the cigarette lighter are electric, you should follow the rules for using electrical devices:

Rules for using the cigarette lighter

— do not exceed the total permitted load on the cigarette lighter (we learn from those descriptions and instructions for devices);

— when using a splitter, it is necessary to add up the power of all consumers;

— we should not forget that the car cigarette lighter is constantly powered to the system and even when the ignition is turned off, the consumption of the connected devices remains. If you do not handle it carefully, there is a risk of complete discharge of the battery or failure of part or all of the on-board network.

There is still some bad news to share

If you connect any (even certified) device to the cigarette lighter socket other than the standard cigarette lighter itself, you automatically lose the manufacturer’s warranty for the car. There are known cases of cars catching fire due to the quality of additional equipment or adapters. This is especially true for Chinese unfortunate manufacturers, but as reality shows, many domestic “businessmen” gladly adopted the experience of their Chinese colleagues and produce “bullshit” no worse, and sometimes even “better” than their opponents.

Perhaps you should think a hundred times before using such devices.

External cigarette lighter

This cigarette lighter is a method of starting a car using an additional source of energy. Two long wires (positive and negative), with an increased cross-section and with “crocodile” clips at the ends, are called “cigarette lighter”. In this way, you can start a car with a dead battery without having to remove and charge it, that is, by connecting the “cigarette lighter” wires to the running car and to the dead battery, you can start it.

Installing an additional cigarette lighter

VAZ 2110 how to connect the cigarette lighter

For some people, one cigarette lighter is not enough, so they need another one - an additional one. It can be installed under the cover of the on-board control system connector, as there is enough space there. Of course, you can do this in another convenient place.

VAZ 2110 does not work from the cigarette lighter

Make a small hole under the connector cover.

Note: It is important that you have access to the factory cigarette lighter wires. It will be much less hassle if you combine the additional one with the standard one. If it is located far away, then a long wire can be used to connect them.

Connect the wires of the additional cigarette lighter with the wires of the standard one. The colors must match each other.

VAZ 2110 no cigarette lighter light

Note: it is imperative to put it through a fuse, which will protect against spontaneous combustion. In principle, a 10 A fuse is enough. Even this will prevent a short circuit.

Place the additional cigarette lighter in the hole already made and secure it.

How to connect a device to a cigarette lighter without a plug

VAZ 2110 connecting the cigarette lighter

It is not always possible to have a plug at hand that will allow you to connect an electrical device to the car’s cigarette lighter. However, you can make a plug yourself:

Note: the case must be leather.

Take two wires and insert them inside the case.

Note: There are usually small holes in the corners of the case. If they don’t exist, then you need to make them yourself. The wires need to be inserted exactly there.

The plus is located in the center of the case, so the positive wire must be twisted towards the center.
In this case, the negative wire should be clamped in the opposite direction (when the cover is completely screwed in).
Insert the resulting plug into the cigarette lighter.

How to connect an additional cigarette lighter

There are several types of cigarette lighters:

Overhead type, equipped with a plastic case, which is mounted in the car interior. There are designs with built-in splitters that allow you to connect several devices (taking into account the permissible power).
Mortise version, which are mounted in holes drilled in the instrument panel and center console.
Temporary type, equipped with power cables with clamps that are attached to the battery terminals.

Where and how to embed

For VAZ, an additional element is attached to plastic covers on the instrument panel or center console. The fixation method depends on the design, for example, a hole is drilled to hold a mortise-type cigarette lighter. The cables are soldered to the terminals of the connected device, and then led out to the relay or directly into the engine compartment. It is possible to use a toggle switch that supplies power when the ignition is off.

Required Tools

Before dismantling the cigarette lighter on a VAZ 2110, repairing it or installing a new device, or replacing a fuse, you will need to stock up on suitable devices. To work you will need:

Phillips and standard screwdriver;
protective gloves.

To fix a broken cigarette lighter or fuse, the following will be useful:

multitester;
blowtorch with solder;
heat shrink tubes, electrical tape;
wire cutters;
needle file

Why did the cigarette lighter break?

Over time, the device may stop working. The most common reasons why a VAZ cigarette lighter breaks.

Blown fuse. The element protects the circuit from wire melting or fire. If the maximum permissible current parameters are exceeded, the fuse fails. It is necessary to remove it from the mounting block. Fuse F18 should be replaced with a serviceable element with the same rating (25 amperes).
Cigarette lighter wiring broken or short circuited. If a car fuse burns frequently, it means there is a short in the circuit. This failure should be diagnosed using a multitester. The wires coming to the cigarette lighter are tested for resistance. The fuse blows.
Poor contact. Over time, the connector on the VAZ 2110 may become loose and the contacts may oxidize, not guaranteeing a good connection. The repair is simple - you need to remove the cigarette lighter from the socket, process the contact points with a file and bend them for better fixation of the device.
Burnt out spiral. The metal thread located inside the device on the VAZ 2110 can burn out due to frequent thermal exposure, and the fuse trips. It is worth replacing the cigarette lighter.
A burnt-out backlight bulb in a VAZ 2110. There is additional lighting around the device itself to help you find the device in the dark. Over time, the light bulb may also stop lighting and the fuse will trip. You will need to remove the burnt element and then replace it with a working one.

Maybe the fuse has blown?

Before removing and replacing the VAZ 2110 cigarette lighter, you should check the serviceability of the protective element. This is a fairly common failure. The car circuit in this area is protected by a 25 ampere fuse. This means that devices with a total power of more than 300 W (12 volts * 25 amperes = 300 watts) cannot be connected to the socket.

Otherwise, the fuse on the VAZ 2110 will blow out. A hint that it was he who “gave up” is the failure of the heater fan. If the device does not work, the fuse should be replaced. The location of the mounting block is to the left of the steering column, behind the decorative panel trim.

To make it easier to pull out the fuse, you should use tweezers. It is necessary to change the part with index F-18. The fuse rating is 25 amperes. It is prohibited to install parts designed to carry high current. An unsuitable fuse may result in a short circuit, damage to wiring cables, or fire.

How to extend service life

Experts provide a number of recommendations that can extend the life of your car cigarette lighter:

use fuses designed for the amperage declared by the manufacturer;
do not connect several powerful devices at once through a splitter (for example, a vacuum cleaner and a pump);
regularly clean contacts from rust and oxides using a needle file;
when connecting foreign devices to the adapter, evaluate the degree of its heating by touching its surface with your hand;
to avoid short circuits, do not clean or bend the contacts with a knife or other metal objects;
replace the fuse with elements designed for higher current strength;
make sure that the spiral wire of the gadget is not too tight;
when leaving the car, remove the plugs from the socket;
purchase splitters and chargers from trusted suppliers;
install paper clips, wire, coins and other foreign objects instead of the fuse.

Replacing the cigarette lighter of a VAZ 2110 with dismantling the tunnel

According to the user manual, the device must be removed by removing the decorative cover of the central tunnel. The instructions will tell you how to correctly remove the cigarette lighter of the VAZ 2110.

Turn off the ignition, open the hood, remove the negative terminal.
We unscrew two bolts securing the cover of the instrument tunnel (see photo).
Carefully remove the wire block.
Now you need to remove the decorative plastic trim under the parking brake.
Unsnap the latches of the gearshift lever cover and remove it.
Unscrew the screw using a Phillips screwdriver.
Move the seats aside, and then remove the screw from the tunnel near the gearshift lever.
The tunnel protective cover should now be easy to remove.
We dismantle the cartridge along with the filter and fuse.
We remove the device in order to repair or replace it.
Installation of the device is carried out in the reverse order.

How to quickly remove the cigarette lighter of a VAZ 2110

There is an easier way that allows you to remove the device without dismantling the tunnel. You can quickly remove the device on a VAZ 2110 as follows:

We de-energize the circuit.
We dismantle the metal cartridge.
Using scissors or a minus screwdriver, we tighten the fixing antennae inside the cartridge and pull it out.
Unclip the wire block.
We dismantle the plastic filter, carefully prying up its edges.

The video will help you understand how to remove the cigarette lighter and replace the fuse on a VAZ 2110 car.

How to connect an additional cigarette lighter

In the interior of a modern car there is a 12 V outlet (cigarette lighter socket or USB port), which allows you to charge smartphones, connect a tire pump, heated seats or a refrigerator. A large number of gadgets forces you to install various splitters or additional sockets in the cabin and trunk. Let's look at the features of this modification.

The process of installing an additional cigarette lighter (12 V socket) is shown using the example of a Lada Vesta car. On other modern LADA cars (XRAY, Largus, Priora, Granta, Kalina, Lada 4×4) all actions are performed similarly. You will find examples of work on other LADA models in the comments.

You can buy a 12 V socket and a USB port on AliExpress (see catalog).

As a rule, the process of installing a 12V outlet does not cause problems.

In the cabin

It is most convenient to place it on the central tunnel of the car. To do this, you need to remove it, cut a hole (use a utility knife) and secure the socket.

Installation process on video:

In the trunk

The 12 V socket is mounted on the casing. To strengthen it, use a piece of MDF or plywood. We cut the hole with a feather drill.

Installation process on video:

Changing the cigarette lighter light bulb

Sometimes the backlight of the device burns out and the fuse trips. This will require dismantling the filter and replacing the light bulb. It’s easy to do work on a VAZ 2110.

Remove the terminal from the car battery.
We take out the metal cylinder.
We bend the fixing antennae and remove the device from the hole.
Disconnect the wire block.
Remove the filter ring.
We squeeze the lamp screen so that the legs come out of the slots.
Remove the light bulb by turning it 90 degrees.
We install a new element, and then assemble the device, following the reverse procedure.

Connecting an additional cigarette lighter

Some car owners install another socket. You will need:

drill or screwdriver with a set of metal drills;
a crown for cutting out a hole, the diameter must match the diameter of the car cigarette lighter;
file;
soldering iron with solder;
wire cutters;
screwdrivers;
multitester;
heat-shrink tubing;
wire of suitable cross-section;
fuse that can withstand the current recommended by the manufacturer - 25 amperes.

We turn off the power to the car and choose a place to connect an additional cigarette lighter. It is desirable that it be a flat surface.
We drill a hole of a suitable diameter and clean the edges with a file.
We connect to the wiring, observing the polarity and passing them through the fuse.
We check the functionality of the model and carry out assembly.

How to connect the device to a cigarette lighter without a plug

Some owners decide to abandon the device itself and prefer to install other devices directly. To connect the device directly without a plug you will need:

We dismantle the car cigarette lighter, gaining access to the cables.
We connect the wires of the installed device, observing the polarity.
We carry out the assembly.

A constant minus. Comes to the car body.
A constant plus. Connects through a fuse to the battery.
Plus, coming up to the backlight bulb.

Cigarette lighter not from ignition

There is a way to connect directly to the car battery. This scheme has advantages: if you connect the cigarette lighter directly to the battery, you can avoid interfering with the wiring itself and the fuse. The work will take less time; the positive cables should be led directly to the battery, and the negative cables should be attached to the car body.

It is also important to remember that you need to select the right spare parts. Initially, this concerns the wires. Each square millimeter of cross-section is designed for 5-10 amperes of current. Should be taken with reserve. A cross-section of 3–5 mm is quite sufficient to transmit the required voltage. Otherwise, the wires may burn and the fuse will trip. This will result in a risk of short circuit. The circuit should be routed through an additional fuse with a rating specified by the manufacturer.

Connecting the cigarette lighter

Never connect the cigarette lighter to the ignition switch. The ignition system will not withstand such a load. Having laid the wire in the engine compartment, bring it to the positive terminal of the battery, connect the fuse and then attach it to the terminal. If for some reason you cannot do this, run a wire with a fuse to the starter and attach it to the positive terminal of the relay. Strip the end of the wire at a distance of 1 cm, place it on the terminal, then crimp it using pliers. Be sure to secure the wire so that it does not dangle anywhere. To attach the wire to the cigarette lighter, use a soldering iron or an appropriate terminal, depending on the device model. Install a fuse and a switch next to the cigarette lighter, this will increase the safety of using this device.

Do not confuse the arrangement of parts of the diagram:

Battery.
Fuse.
Switch.
Relay.
Cigarette lighter.

The switch must be designed for a current of 1.5 times the maximum load. If there is no such switch, attach a relay next to it that is suitable for the current. Some drivers place a switch and relay next to the ignition switch. Connect the switch to the control contact of the relay, and the cigarette lighter to the power one. To do this, place heat-shrink tubing on the exposed ends of the wire, then push and crimp the terminals. Adjust the tube so that it completely covers the junction of the terminal and the wire, then heat it with a match or lighter. You can also install a regular cable splitter (220 volts), which is sold in hardware stores. Find the nearest ground connection location (the wire is bolted directly to the body). Unscrew the bolt, clean the contact pads of the terminal and body. Route a piece of wire from the relay and cigarette lighter to the ground hole to determine the length, then cut and strip the ends.

Make a splitter - take a piece of wire of a suitable length, strip both ends. Then solder the ends of the long and short wires to each other so that they both point in the same direction. Protect the connection with heat shrink tubing, then attach the connection terminal to the negative of the cigarette lighter. Position the tube so that it completely covers the contact point. Place heat shrink tubing on the other end of the short wire and attach the terminal. Or use a regular cable splitter, which must be rigidly attached to the body.

Installation check

Check all connections carefully. The relay and splitter must be securely attached to the housing. After making sure that everything is in order, check that the ignition switch is turned to the off position and connect the battery. Using a tester, measure the voltage on the unconnected battery. Place the negative terminal on the corresponding battery terminal and measure the voltage again. If it hasn't changed, then everything is fine. If it drops by at least 0.5 volts, turn all electrical appliances on and off, including the ignition system. If the voltage does not rise, disconnect the battery and look for a short circuit. If everything is fine, turn on the switch and measure the voltage on the battery again. After making sure that everything is correct, measure the voltage at the cigarette lighter contacts. If everything is in order, you have successfully completed the job.
