Selection and replacement of the battery on a Ford Focus car

The standard battery for a Ford Focus (2nd and 3rd generations, which are common in the Russian Federation) is designed for 3 years of operation. Subsequently, its capacity and starting current values ​​are sharply reduced, which is why the starter rotation speed when starting the engine also decreases. Sooner or later, this leads to the fact that the battery current drops to such values ​​that it is impossible to start the engine at all, and at the same time it becomes impossible to charge the battery. In such cases, the only option is to replace it with a new one.

The standard battery for a Ford Focus (2nd and 3rd generations, which are common in the Russian Federation) is designed for 3 years of operation. Subsequently, its capacity and starting current values ​​are sharply reduced, which is why the starter rotation speed when starting the engine also decreases. Sooner or later, this leads to the fact that the battery current drops to such values ​​that it is impossible to start the engine at all, and at the same time it becomes impossible to charge the battery. In such cases, the only option is to replace it with a new one.

Features of the battery for Ford Focus

The manufacturer's concern installs batteries of size 242x175x175 (the so-called “European”) in Ford Focus of both the 2nd and 3rd generations. This is the original size, but shorter ones also fit and do not dangle due to the presence of a lock. Exceptions are cars with a diesel engine, where the battery is 190 mm in height (increased capacity).

The battery capacity differs in different engine variations:

It is recommended to replace it with a compatible battery of the same capacity; this will ensure the optimal mode of the charging system (in this car it is “intelligent”).

Also, when choosing which battery to install, you need to pay attention to its maximum starting current. You can install a battery with this value higher than that of the original battery, but you cannot set it lower. For Ford Focus gasoline internal combustion engines, the current must be at least 540 A (in the technical documentation for gasoline 1.6 engines, a minimum of 510 A is indicated), for diesel engines - 680 A. With lower values, the battery may also be suitable, but the load when the ignition is turned on will be critical, which reduces the service life of the battery.

Reverse polarity is required (positive terminal is on the left). The terminals are standard (with a “snap-on” connection).

Main selection criteria

The most difficult thing is to determine what kind of battery is needed for a particular car. The following parameters are taken into account:

1. Polarity (position of positive and negative terminals). In European and American-made cars, reverse polarity is predominantly used, where the positive terminal is the left terminal. In Japanese, Korean and Russian - mostly the other way around.
2. Dimensions. In most modern cars, the battery is installed in a specially designated compartment. Naturally, it has size limitations that should be taken into account when purchasing a replacement battery.
3. Capacity. Indicates the storage portion of the charge. It is recommended to choose a battery with the same capacity as was originally installed by the manufacturer - the charging system is designed to work optimally with a specific range.
4. Starting current. It must be no lower than that originally set by the manufacturer. The more powerful and massive the engine, the higher the starting currents are needed for it, because more effort is required to spin up a heavier unit.
5. Production technology. It is also recommended to use the same type of battery as was originally installed. But the manufacturer in the technical documentation may indicate compatibility with other types of batteries.

It should also be taken into account that one car model can be supplied with different types of batteries. For example, the same Ford Focus is supplied to the Russian Federation in two variations: 2nd and 3rd generations, which, although slightly, differ in technical characteristics.

Step-by-step replacement instructions

To remove and replace the 3rd generation Ford Focus battery, you only need a wrench with a 10 mm socket and an extension. For the 2nd generation Ford Focus, you will also need a screwdriver to press out the latches of the plastic cover (they are more rigid and difficult to pull off with your fingers). Another nuance: in a car with a 1.6-liter gasoline engine, you do not need to remove the air filter. For diesel and petrol 2.0 liters – mandatory. Therefore, before removing the battery for replacement from a Ford Focus 3, you should check the type of installed engine in the technical documentation. If its power is 150 horsepower, then the filter must be removed, since without this it will not be possible to get to the battery. For internal combustion engines of 105 and 125 horsepower, this is not necessary. Otherwise, replacing the battery is carried out similarly according to the following algorithm:

All that remains is to replace the battery with a new one. Assembly is carried out in reverse order. In the 2nd generation Focus, where restyling has not yet been carried out, although the filter does not need to be completely removed, without an extension cord it will not be possible to unscrew the battery lock. And if a non-original battery is installed, that is, with smaller dimensions, then the latch moves in the compartment (there are moving grooves for it).

After installing a new battery, you will also need to reset the control unit. To do this you need:

Once the reset is complete, the battery icon on the panel will light up - this confirms that the procedure was successful. In this way, intelligent charging is “reset” and configured to work with a new battery.

So, it is recommended to change the battery in a Ford Focus after about 3-4 years of active use. The whole procedure takes 15–20 minutes. It is not necessary to charge a new battery before installation if its charge is sufficient for at least the first start of the engine. And most importantly, do not forget to reset the BMS settings, since without this the control unit may not work correctly (for example, lower engine speed at idle).

Workshop battery replacement for Focus 3 Ford (battery Focus 3 Ford)

A battery is a device that stores electrical energy during engine operation. It is consumed by the devices and mechanisms of the electrical equipment of the vehicle.

This mechanism is intended to maintain the required voltage in the on-board network and the ability to start the motor unit. The battery is used as an auxiliary power source for instruments and systems of the machine when the power unit is not working.

The battery is charged due to the operation of the current generator during operation of the Ford Focus 3 car.

Replacing the Focus 3 battery: preliminary information

Battery structure

• composite body divided into sections (cans);
• lead electrodes;
• electrolyte (acidic liquid saturated with electrons);
• output contacts for electrical energy selection;
• openings of sections with plugs for maintenance.

The principle of operation of the battery

The battery device contains sulfate acid, a negative lead cathode and a positive lead dioxide anode. This unit is characterized by the presence of six sections connected to each other according to a special electrical circuit.

They produce 2 V of nominal voltage, the final battery indicator is 12 Volts. When a battery is discharged, a chemical reaction occurs, as a result of which the cathode undergoes reduction phenomena, and the anode undergoes oxidation reactions. This occurs through the presence of sulfuric acid.

In the case of a load on the battery, the lead plates react with an acidic substance. This leads to a flow of electrons and provides energy to the on-board network and consumers. The charge is carried out from a generator or a special device, during which a chemical process occurs that is reverse to the discharge.

Battery power is taken by installing special terminals on the output contacts.

Ford Focus 3 battery replacement: prerequisites

• occurrence of ECU messages about low battery charge;
• occurrence of malfunctions in electrical equipment;
• presence of difficulties in starting the motor complex;
• rapid onset of a discharged state of the Ford Focus 3 battery;
• the device does not accept charging;
• increase in battery temperature;
• there is an uncharacteristic unpleasant odor in the area where the battery is located;
• presence of electrolyte boiling noise.

The causes of possible problems are usually as follows:

• untimely performance of maintenance;
• expiration of the working life of the battery unit;

• 
  independent inexperienced actions to perform technical manipulations;

• improper use of the battery, not in accordance with the manufacturer's instructions;
• physical damage to the frame shell;
• insufficient amount of electrolyte in the Ford Focus 3 battery sections;
• incorrect functioning of the voltage relay regulator (overcharging leads to boiling of the acidic substance of the cans);
• inappropriate operating cycle (the battery device is systematically in a discharged state due to rare, short trips);
• malfunctions in the operation of consumers (use of high starting current values);
• the occurrence of short circuits and destruction of lead plates.

Ford Focus 3 battery replacement: preliminary diagnostics

Technological operations of this configuration are characterized by their specific execution and require verification activities in the conditions of specialized service stations.

These manipulations are carried out using special instruments, equipment and devices that make it possible to determine the operating parameters of possible breakdowns.

Work to detect faults begins with an external inspection of the battery for mechanical damage, leaks, oxidation of contact electrodes, improper fastening of terminals and compliance with connection polarity.

The battery is then examined using a load fork. This device is connected to the output contacts and is designed to simulate workloads and the time the battery holds the correct charge. This method allows you to determine the operating life of the battery and the need for maintenance.

After this, using a specialized tester, the density of the electrolyte and its quality characteristics are determined. Using a special device, check the level of acidic liquid in each section of the battery assembly.

This makes it possible to determine the technical condition of the battery. Specialists are also clarifying the chemical composition of the technological acidic substance.

Determining these indicators allows you to assess the physical condition of the plates and the power source as a whole.

Ford Focus 3 battery replacement

These restoration measures have a certain sequence of actions and must be carried out by qualified electricians from reliable service centers using the necessary equipment and tools.

Replacing the Ford Focus 3 battery

Replacing the battery of the Ford Focus 3 remote control key fob should be carried out in specialized service organizations with the involvement of qualified electronics engineers.

The key fob contains a special chip and a transmitter that provides the corresponding signal to the ECU anti-theft system receiver. This is achieved through pre-synchronization with the receiver.

The power of the signal emitted by the key fob and the reaction speed of the car's electronics depend on the state of the remote control battery. To replace it, remove the power compartment cover by operating the latch mechanism.

Next, the battery is removed and a new battery is installed.

How to change the battery for Ford Focus 2 restyling and pre-restyling

Unscrew and remove the bolt that secures the “-” wire to the body mass, so to speak, of your car.

Before installing the battery, do not forget to clean the terminals and tip surfaces (from the inside). This can be done with fine sandpaper. Do not mix up the wires when connecting. After connecting the wires to the battery, lubricate the exposed parts of the terminals and the metal ends of the wires with a thin layer of grease (or something similar).

I think there are no more questions with the question of how to remove the battery from a Ford Focus 2!

Installing a new battery

For all those who are going to purchase a new battery, if there is a need to replace their old one, it is worth repeating that its height should not exceed 175 mm. Some craftsmen manage to squeeze a 190 mm high battery into the allocated limited space, but this will definitely cause additional difficulties during replacement. We will not experiment and will install a sample of standard sizes. We tilt it forward and install it in its normal place.

We begin installation by “dressing” the bracket: fixing the battery to the bolt located on the right side and tightening it using a ratchet and a 10mm socket.

Install the front part of the box. This operation is not easy, since the part must be squeezed into a small space on the right, while constantly removing interfering wires in the end part.

We put the wires in the clamps.

We put the terminal on the positive terminal and tighten its fastening.

We insert the negative wire under the bracket, put it on the corresponding terminal of the battery and tighten the terminal fastening.

We put the second end of the bracket on the bolt, screw on the nut and tighten it.

In order for the cover to be put on without problems, the negative cable must be placed in the slot intended for this.

The finishing touch is to install the lid in its place.

Agree that the information in our article made it easier to perform this rather wise operation.

Every second motorist has encountered the problem of a dead battery. The reasons for sudden wear and tear are different: poor workmanship, violation of operating conditions, defects, exhaustion of its resource.

The decision to restore the battery (reanimation) is made by the service station master, who conducts a comprehensive diagnosis of the technical equipment.

Device programming

The key fob does not always start working after replacing the power source. First of all, you need to check whether the battery in the car is dead. To do this, you can directly try to start the car or turn on the headlights. If the battery is in working condition, then the key needs to be reprogrammed, since the car does not “see” it.

To do this, insert it into the ignition switch and turn it to the 2 o'clock position four times in a row. Then return it to 0 and wait for the sound signal. This will take about ten seconds. A sound will be heard, which means programming has begun. Now quickly press the button on the key. The lock should click, which means the key has received a new program.

Guide on how to remove the battery from Ford models

Ford Kuga car

The design features of Fords prevent independent intervention in the operation of technical components and electronics. What should I do if the battery needs to be replaced? Many Ford engineers in its homeland consider it natural to contact a car service center and, if necessary, call a tow truck.

The traditions of driving and servicing cars in Russia have taught car enthusiasts to overcome all obstacles and change the battery with their own hands. Once you figure out how to do this, there are no questions later.

Depending on the car model, the battery is available to varying degrees. If you have little experience in dismantling, before unwinding and disconnecting, take a close-up photo so that you can accurately restore the connections later.

For a comfortable view and, if necessary, to remove the battery from a Ford Focus 2, 3, restyling strictly in a position without tilt (for example, a cracked housing), it will be convenient to remove the air filter.

Find out the charging time of your battery

Let's figure out how to remove the battery from Ford Focus 2, 3, restyling, without removing the filter:

The second generation of Kuga was released in 2013, despite noticeable changes in the body, the location of the battery in the Ford Kuga 2 has remained recessed since 2013; access to it is gained by removing the air filter, or by dismantling the shelf under the front window, which is also called a frill.

In car repair shops, it is customary to remove batteries on Ford Kugas after first disassembling the air filter.

For an experienced electrician, dismantling it is not difficult; the method has important advantages over gaining access through the top:

Ford Focus 3 battery removal procedure

FordFord Focus 3

The battery is an extremely important part of any car. With its help, the engine is started and power is provided to various electrical devices. If it breaks or is discharged, then you will not be able to operate the car. How to remove the Ford Focus 3 battery? This is quite simple to do, and we will provide more detailed instructions in our article. Of course, it’s better to watch the video, but if this is not possible, then just follow our recommendations.

The battery requires some maintenance. Once a year you need to check the electrolyte level and charge if necessary. This will allow you to avoid problems and use the battery for a long time.

However, this does not guarantee that one fine morning the third Focus will not start due to a dead battery. This is especially true in the cold season, when the last thing you want to do is spend time servicing your car. In this case, the battery can be replaced, but to do this you need to know how to remove the battery.

Features of battery removal

So, first you need to open the Focus hood and remove the air filter. To do this, perform the following steps:

• remove the rubber pipe by pulling it towards you;
• a metal clamp will open in front of us, which also needs to be removed;
• Pull the red lock up and disconnect the connector;
• remove the pipe from the air duct that leads to the filter;
• release the wires of the connector that we talked about earlier;
• With a slight shake, we remove the “air blower” box, which stands on rubber washers, and in the lower part it is not secured in any way.

Finding the fault

If the check battery icon lights up and remains on when the engine is running, the first thing you need to do is test the charging. It is necessary to attach the contacts of the multimeter to the output terminals. If the battery works correctly and is fully charged, the device will display a voltage of 12.5V, but if the characteristic drops beyond 12V, the battery should be removed and additionally recharged, having learned in advance how to charge the Ford Focus 2 battery.

Next, the generator itself is tested. Wires are connected to the terminals and with the engine running, check the voltage with a multimeter using the positive terminal. At idle speed and switched off consumption, the tester should show about 13V, when the speed reaches 3000, the voltage should increase to 14.4V. Then it is necessary to activate electrical consumers and increase the load. The characteristic must remain at the level of 13V, otherwise it can be stated that the generator is faulty, which is why the battery is dead.

You can test the functionality of the generator, regardless of the location of the battery, using a simple method - with the engine running, you need to disconnect the wire from the positive terminal of the battery. If the engine stalls, the problem is in the generator.

The instrument panel and optics lights, adjusted by the number of revolutions, indicate a problem in the generator system or a decrease in the drive belt tension. Diagnostics of the voltage relay, if the battery is discharged or low, is quite possible by applying voltage from the battery to the contacts. In a situation where the generator brushes show 12V, the relay is working properly, but otherwise the unit requires replacement.

How to select and, if necessary, replace the battery in a Ford Focus 2?

To ensure the normal operation of electronic devices and devices in the car, a powerful battery must be used. We are talking about cars from any manufacturer, including American-made cars, which are characterized by the presence of many voltage consumers. In this article we will talk about how to choose the right battery for a Ford Focus 2 car and how to replace it.

Criterias of choice

The choice of battery for the first, second or third Focus should be in accordance with the manufacturer's recommendations. According to experts, today when purchasing, you should pay attention to a dry-charged battery. One of the key advantages of such devices is their long shelf life and, accordingly, service life.

In addition, dry-charged batteries are characterized by the following advantages:

Ford Focus engine compartment - battery is covered with a lid It is impossible to say exactly which battery is best to buy for Ford Focus 2, since products from different manufacturers have both advantages and disadvantages. To choose the most optimal option, you should be based on your experience, as well as recommendations from Focus owners. Today, the most popular batteries among domestic buyers are Warta, Bosch, Viking, etc. batteries. Such models have long established themselves as reliable batteries that rarely fail. Of course, you can choose other manufacturers, but the most important thing in this case is that the device fits Focus 1 or 2 sizes.

So, to select the correct battery, you should take into account the recommendations of the automobile concern, as well as the technical characteristics of the vehicle. For example, if the capacity size must correspond to 70 Ah, it is not recommended to buy a battery with a different capacity. Of course, sometimes you can deviate from this rule and purchase a battery with a smaller capacity, but this is true for Focus 1, 2 and 3 cars, which use more viscous oil. In addition, a lower capacity is relevant for vehicles that have problems with the ignition or power systems.

Same engine compartment - battery cover removed

It is worth considering that in some cases it is necessary to install batteries with a larger capacity. In particular, we are talking about cars equipped with various electronics - GPS devices, video recorders, powerful sound systems, monitors, etc. When driving on the highway, a conventional battery can cope with powering such devices, however, when driving around the city and in traffic jams, the car owner may encounter certain problems. So when purchasing a device, you must first of all be guided by the features of your vehicle.

So, what features need to be considered when purchasing a battery:

Instructions for dismantling and replacing the battery

In general, replacing a battery is a fairly simple task that any car enthusiast can handle. To perform this procedure, you only need to prepare in advance the wrench needed to remove the terminals. It should be borne in mind that the battery itself is a rather heavy device, which will require some effort to dismantle.

Algorithm of actions

To remove the battery on a Ford Focus, follow the steps:

Sorry, there are no surveys available at this time.

Video “How to properly replace the battery on a turbodiesel Focus”

Instructions for replacing the battery on a Ford Focus with a 1.8-liter engine are presented in the video below (the author of the video is Pavel Menshakov).

When it's time to change

Car batteries offered on the market demonstrate impressive durability. If the operating rules are followed, acid batteries from well-known brands last 4-5 years or even more. But this, unfortunately, does not always happen.

The battery requires replacement in the following cases:

• After 3-4 years of intensive use, if signs of incorrect operation are detected;
• There are difficulties starting the engine, including in the warm months of the year;
• The battery quickly runs out without recharging when you turn on the dimensions, multimedia, and other on-board devices;
• Mechanical damage to the battery.

If during operation of the Ford Focus 3 the battery icon lights up on the dashboard, this may indicate a fault. But not necessarily - a battery error also appears when there are problems with the generator and charging regulator. In any case, you should contact an auto electrician. You should not rush to buy a new battery prematurely, much less try to restore it.

There are no effective ways to restore exhausted batteries. For a short period of time, the device can be restored to functionality. But this will most likely become the agony of a dying battery, which can fail at any moment.

Removing the battery - step-by-step educational program

Armed with a 10 or 13 wrench (this tool has a small head and an extension for ease of operation), it will be easier to think further about the question of how to remove the Ford Focus 3 1.6 battery. Then we proceed as follows:

1. Unscrew the positive terminal. The negative one cannot be touched because it is difficult to reach.
2. The plastic cover will have to be removed so that nothing interferes with the procedure.
3. Remove the clamping bar, held by two nuts, with a wrench.
4. To avoid simultaneously removing the air filter and replacing its clamp, you need to lift up the cover with the positive terminal of the battery. By pulling the battery towards you, it will be convenient to unscrew the negative terminal.
5. By unscrewing it, it is easy to pull out the device.

As can be seen from this manual, the question of how to remove the battery on a Ford Focus 3 is not difficult to solve. In this case, it is important not to confuse the polarities.

We service the battery. Removal/installation.

Imagine that your Focus, purchased not so long ago, maybe a little more than six months ago (color, body, engine size and equipment do not matter), one fine day refused to start. Instead of the usual sound of the starter turning, did you hear a click-click-click-click-click-click?

Congratulations - you also got it! (You can find and discuss the reasons for battery discharge in this topic All about the battery) Of course you are right, what normal person would try to measure the density of the electrolyte in a NEW car. (I thought so myself too. Now I’ll do this on a new car too

But emotions aside, let's get to the point: the battery is discharged - that's a fact. But don’t rush to “just charge” it. As you know, Focuses are equipped with calcium batteries. This is the whole problem. Be sure to check the density of the electrolyte. Pay attention here. My density was 1.15 - this is below all permissible limits. Therefore: 1. If you do the same, then point 2 is NOT FOR YOU. 2. If your readings are about 1.20 or higher, then first try to charge it, but not like a regular battery, but with a low current of 1-2 Amps for 2-5 days. (Be sure to make sure there is no strong boiling). If it doesn't help, read on.

So you have 1.15 or so. Alas, nothing can be done here. And no amount of charging will bring the battery back to life without damaging your health and resource. There is only one way out - replacing the electrolyte (although this concept is not practiced by specialists). It was not for nothing that I mentioned at the beginning of the topic that your car should be up to six months or a little more. Then this procedure should be as painless as mine. Just during the replacement process, the battery will have to be turned over. On aged and old batteries, this is fraught with short circuits due to sediment at the bottom of the battery.

So further in order: 1. Go to the Auto Parts store and buy 3 liters of electrolyte. The capacity of this battery is about 2 liters. But you need a reserve, you never know if you spill it past, and then the electrolyte is sold mostly in 1.5 liter bottles. Therefore, 3 liters is just right! (Just under no circumstances tell you why you need it. They may dissuade you. Remember: YOU HAVE NOTHING TO LOSE. If you charge, then if you are lucky and reach the coveted 1.27, then the process of such a long charging will reduce the battery life by at least half.) 2. Take your battery out of the house and remove the plugs. 3. Pour out the unusable electrolyte. (It is better, of course, to dig a small hole). Just don't pour it down the drain. This is still rubbish. In this case, we choose the lesser of two evils. 4. Fill in new electrolyte. The most important thing here is to minimize the time between draining the old one and filling in the new one. The plates do not like open air. Close the traffic jams. 5. Carry the battery home. Open the plugs and charge it with a low current of 2 Amperes. The density of store-bought electrolyte is 1.27-1.28. After pouring into the battery, it should fall a little, mixing with the remnants of the old one. 6. Use a tester and a hydrometer to control the process. When the voltage on the battery is 15.7V (I couldn’t do it anymore after 6 hours of charging), and the density is 1.26-1.27, you can consider that the battery is charged and turn off the charger. After the battery cools, the density will rise a little more. 7. Install the battery on the car and enjoy the usual cheerful sound of the starter.

Brands

Bosch and Varta have become popular batteries for Ford Focus 2 1.6 restyling (100 hp).

Which battery to install on Ford Focus 2 1.8? Varta, Bosch, Moll, Tudor have quality comparable to prices. Moll is the most expensive option. It has a well-thought-out design of increased strength.

There are practically no complaints about Tudor batteries when working in severe frosts. Bosch and Varta are 2 brands of the same manufacturer, the most common among car enthusiasts due to their relatively reasonable price and sufficient reliability for 3-5 years.

The original with the Ford logo is not popular among car owners. The price-quality ratio is noticeably inferior to those listed above.

Characteristics of batteries of famous brands

Russian service centers mainly install the following models to replace the original battery in a Ford Focus:

1. Varta Blue D Stated characteristics: capacity – 60 A*h, starting current – ​​540 A. Average cost – 3450 rubles.
2. Berga PB Capacity - 60 A*h, starting current - 540 A. Average cost - 6200 rubles.
3. Autopower A60-LB Capacity – 60 A*h, starting current – ​​540 A, average price – 4800 rubles.
4. Varta Blue Dynamic. Capacity – 74 A*h, starting current – ​​680 A, price – 7000 rubles.

All of these models refer to low-antimony batteries. Helium ones have better characteristics, but also cost several times more.

How to remove the battery on a Ford Focus

Author: Sochi Auto Repair

The Ford Focus brand uses a battery with a nominal voltage of 12 V and a capacity of 60 Ah. The battery cover and housing are made of polypropylene. There are holes on the battery cover designed to add water, and also used as ventilation holes. In addition, an indicator indicating the density of the electrolyte can be installed on the lid. How to remove the battery on a Ford Focus - simple instructions in our material.

To remove the battery from a Ford Focus, you will need a wrench with a 10 mm socket head and an extension.

The battery has a significant mass. Before you remove the battery on a Ford Focus, you need to make sure that you have enough physical strength to lift it. Turn off the ignition and all electrical equipment. The wires must be disconnected from the ground wire.

On vehicles with 1.8 or 2 liter engines as well as turbodiesels, before removing the battery, it is necessary to remove the cover installed on the air filter.

Diagnosing other problems

Many situations require knowledge of where the battery is located and how to remove the battery. Let's look at diagnosing and repairing various problems:

• A situation occurs when the multimeter on the dashboard shows the charge, the battery charging indicator does not activate at all, and the voltage at the battery terminals is about 12V, while the battery is completely discharged. You can solve the problem by stripping the terminals on the battery - if this does not help, you need to measure the voltage at the generator. One of the electrodes is connected to terminal 30, and the second is placed on ground. In situations where the voltage is greater than the battery specification, “30” must be cleaned with sandpaper. You should also carefully inspect the wiring from the generator to the battery for breaks.
• The on-board voltmeter and indicator indicate charging, the voltage at the battery terminals is about 14V, while the battery is discharged, and when the load increases, the voltmeter indicator goes to a minimum. This is all due to weakening of the tension, wear or breakage of the belt. The slack belt should be tensioned so that when pressed, it bends 1 centimeter.
• The situation may also arise as a result of a breakdown of one of the generator diodes. The motor is turned off and the entire diode bridge is rung, and any faulty elements found must be replaced. It is necessary to test the generator brushes - if their length is less than 5 mm, the parts should be replaced.
