I recently went out to order, for which I took my old gas generator with me. During the process, his voltage dropped sharply, and after that he did not produce 220 volts. Since I did not have the equipment necessary to check the serviceability of the gas generator with me, I returned to the workshop, where I began a full diagnosis of it. And then I’ll tell you about possible breakdowns and malfunctions of the gas generator, due to which the generator may not produce the required voltage.

What is a gas generator
Gasoline generators can be considered mini power plants. The principle of their operation is to burn fuel and convert its internal energy into electrical energy. The components of a gas generator are an internal combustion engine and an electric generator itself.
One of the types of gasoline generators is inverter gasoline generators. Their difference is the presence of an inverter and a PWM unit (pulse width modulation).
Like any equipment, generators can also break down. Below I will talk about several of the most common causes and troubleshooting methods that may cause the generator to not produce 220 volts.

Typical voltage indicator in a VAZ-2110 generator
In order for the car to work properly and not fail on the road, the car enthusiast must constantly monitor the technical serviceability of his own “four-wheeled friend,” while paying a lot of attention to the car generator. If the unit fails, the battery will not be able to receive electronic recharging; ultimately, the car will work only from recharging the battery, the supply of which will last for a short period of time.
The engine does not gain the declared power
There may be the following reasons, with recommendations for elimination:
- The spark plugs are not tightened enough (to fix it, you need to either replace the spark plug gasket or simply tighten it).
- The cylinder head does not fit tightly (in this case, simply tighten the fastening bolts more tightly, or simply replace the gasket).
- Piston rings are worn or seized (replace rings).
- The cylinder or piston is worn (repair or replace).
- There may be poor contact between the working chamfers of the valve and the seat (either repair or replace).
- The piston rod is stuck (again, replacement or repair).
- The size of the gap between the valves may differ from the specified gap size of this model (to eliminate this, you need to adjust the gap size).

Problems in the ignition system
Ignition system malfunctions:
- The spark plugs may be faulty (just replace the spark plug).
- Ignition coils are faulty (replace coils).
- The air gap between the flywheel and the ignition coil differs from that provided by the manufacturer for this model (adjust the gap size).
- The magneto may be demagnetized (replace the magneto).
Problems with the fuel system
Fuel system malfunctions:
- Clogged carburetor (to remove it, disassemble and clean the carburetor itself).
- Clogged hose or filter (clean the hose or simply replace it).
- Air may enter the fuel hose (all connections must be checked and adjusted).
- Another problem may be low quality fuel or it is diluted with water (use higher quality fuel).
Weakness of air flow
Air duct problems:
- Clogged air filter (clean or replace the filter itself).
- The fuel choke may be faulty or broken (repair or replace it).

Generator maintenance for preventive purposes
VAZ 2112 malfunction in the generator
First, let's look at how the generator is serviced:
- First of all, this means cleaning the external surfaces.
- Generator maintenance also involves checking the attachment of the device to the engine.
- In a thorough check of the reliability of attachments with a generator and voltage regulator.
- It is also necessary to check the generator drive belt, because if the tension is weak, the device will not function normally. It is recommended to carry out this same check every 10 thousand kilometers.
- It is also necessary to check the condition of the generator belt, which should not have any cracks or delaminations.
VAZ 2112 generator malfunction
The condition of the bearings is checked (see Replacing generator bearings on a VAZ 2112 on your own) of this device. This check involves removing the belt and rotating the rotor by hand. If jamming or play is detected during the process, as well as clicks or noise, the bearings will have to be replaced.
Troubleshooting procedure
Check the gas generator for serviceability or diagnose the electrical part of the equipment only when the external line is disconnected - make sure that the wires are not connected to the output terminals, otherwise discard them
Voltage rating measurement
The very concept of “Doesn’t show tension” is very vague. Therefore, the first thing you need to do is check whether there is at least some voltage or whether it is completely absent. This first of all gives the presence of a nominal value, even if it is greatly underestimated, this indicates that there are no serious breaks in the circuit. Such a primary diagnosis greatly facilitates solving the problem.
Visual inspection of the device
Any repair of technical equipment, regardless of the type of breakdown, should begin with this. Look at all the parts, elements and circuits of the gas generator that are in sight. If your unit vibrates during operation, then, as a rule, most of the faults are related to the contacts, or more precisely, to their weakening. The solution is very simple - after checking the reliability of all connections, including the electrical part, carry out a “tightening” if necessary, but it won’t hurt for prevention.
Generator check
The generator is an electric motor that generates voltage that is removed from the windings during forced rotation of the shaft. It will not be possible to repair the generator yourself without the necessary tools, but diagnostics can be done. To do this, you will need at least a simple multimeter - if it does not produce voltage, then it should already be clear where the breakdown or malfunction is.

Checking the condition of the current collection brushes
Some models of gasoline generators have current collecting brushes, and one of the typical faults for these models is the breakage of one of these brushes. Therefore, you need to check the integrity of the windings. To do this, it is quite enough to disconnect one of the terminals of the winding, and then “test” it. If after checking with a multimeter there are several ohms there, then everything is in order.
Only a professional can diagnose a case of rotor demagnetization. So it's just a matter of going to the workshop for a check.

Checking the electrical circuit
If the generator is working properly, and the voltage is removed from its windings, which is then supplied to the electronic unit, but there is some kind of breakdown, then it is necessary to find the area where the voltage disappears. When measuring alternating voltage, you need to check the test points with a multimeter probe.
You will have to determine these points yourself, taking into account where it will be most convenient to take the measurement. Thanks to this technique, you can not only find the location of the circuit break, but also the faulty radio component in order to replace it.
Load check
Each gas generator is characterized by its own specific electrical power: if several consumers are connected to the power line, then with an increase in the total value of their respective parameters, the device may simply not produce voltage. The reason for this is the activation of the protection circuit (shutdown).
This is very easy to check: if the voltage at the output of the gas generator in stand-alone mode is normal (not too low or “jumping”), but after connecting the external line some malfunctions appear, then the load on your device is greater than the maximum permissible.

I recommend the following video, in which the author talks about possible reasons why a gas generator may not produce 220 volts:
The generator does not provide charging and voltage VAZ-2114: reasons, repair
Sooner or later, the VAZ-2114 generator will stop providing the necessary charging, which will create a lot of troubles and problems. It’s just that at one point the car may not start because this unit has not properly charged the battery. This article tells you how to find and fix a problem in the form of incomplete charging of the generator.
about the reasons for the lack of charging on the battery
The material will tell you how to disassemble and repair a car generator, and also talks about some of the subtleties and nuances.

As a result…
If your gas generator does not produce voltage, then I talked about possible malfunctions; there should not be any other faults than those indicated. The design of a gas generator is very simple, so finding the cause of a malfunction due to which there is no voltage is not difficult if you have its electrical installation diagram and a multimeter. And also use the tips above to fix your gas generator.
Question
Write in the comments which brand of gas generators do you think are the best?
Primary signs of on-board voltage sag
In the most advanced cases, a drop in on-board voltage can be noticed without any measuring instruments. The primary signs of this defect include the following symptoms:
- chronic undercharging of the battery;
- audio system sound clipping;
- dim headlights;
- dashboard flashing during peak loads;
- floating engine speed.
For normal charging of the battery from the generator while driving, the voltage in the on-board network must be maintained at about 14.4 V. If due to drawdowns it is less, then the battery is never fully charged, may fail during a cold start of the engine, and also deteriorates as a result of sulfation of the lead plates.
Clipping is a type of sound distortion that occurs when the amplifier's output voltage exceeds the supply voltage. Most often it manifests itself in the form of wheezing from the speakers when the volume is turned up.
Dim lighting or flickering lights indicate that the lamps simply do not have enough voltage to operate at full capacity.
As for floating engine speeds, this is more often observed on cars with numerous electronics and various sensors. There is not enough voltage to operate all this, and the engine control system malfunctions when there are significant drawdowns in the on-board network.

Valerii Kliuchnikov, 28 years old I drive Lada 112 Coupe Nazarovo, Russia
The problem of such a car in 2008, europanel. I decided to replace the tidy fresher because My start to do strange things. Found in ads dashboard with fresh Kalina, and the price is sweet, only 1,000 rubles, and the mileage on it 800 km. The owner said that as a car bought with the cabin itself immediately ordered Gamma (tidy), and this put. Well. I take away this tidy myself giving 1,000 rubles. Sticks and what I see I do not charging battery on the panel lights up, I gazanul to 2500, charging gone, the light went out. I put my old no such tidy. What could it be, I want a new tidy and want to charge was?

People, tell me how to solve the problem - when starting the engine, the dashboard lamps light up very dimly (I installed LEDs for brightness), after increasing the speed (reversing the throttle), the lamps light up brightly. I changed the charging regulator, but the problem did not go away. Help with advice!
There may be a diode in the tidy!)) And in the tenth tidy there is a lamp! So think about it)))
That is how it is
put resistance and everything will be ok.
Google it, there is info just like I did for myself.
Yes, not brushes, I plug in the old tidy, everything is fine
Well, just in case, check with a battery voltmeter how much current the generator produces to the battery.
I connect the diagnostics, start the car, the voltage is 12 volts and the light comes on, the gas is up to 2500, the light goes out and the voltage becomes 14.2.
Well, that means brushes after all. There is no reason for the tidy. When the brushes rotate, the voltage is pressed and a
No, that's all I found on the Kalinovskaya tidy, the generator from 2110 will not be excited because... in the 2110 tidy there is an incandescent lamp for excitation, and in the Kalinovskaya there is an LED
Clear))) Valera took on the tuning))
Tomorrow I'll go to the 16th with slippers))) April 1st to the body workers, and then the forehead)))
The brushes on the generator are worn out)))
Charging periodically disappears.
Like “What to do”, “who is to blame”, etc.?
Charging periodically disappears, and the periods are long - from a week to a month. It starts simply - the on-board electrics fail - if you turn it off, it won’t start, the battery is dead, the starter won’t turn over. at this moment, when you turn on the ignition, AS A RULE the battery light does not light up; if it does start, the light does not light up either.
Removing the tablet to inspect the brushes is also normal, they are not worn out or sunk. checking the wires from the gene to the battery, the battery to ground, the engine to ground - everything is fine, the terminals are clean.
After charging the battery, it starts and, when checked with a voltmeter, there is charging. let's go. Every day we climb under the hood with a voltmeter to check - there is charging. at idle 13.9 volts. If you turn on the headlights, heater, heated glass, then 13.6. There is no voltage drop on the wires. or rather the difference is 0.1 volts between the positive of the battery and the positive of the generator (more on the gene)
Reason #1. Erroneous measurements
First of all, you need to understand that the normal voltage of the on-board network must be “looked for” directly at the battery terminals. Not in the salon. Not in the cigarette lighter socket. Not anywhere else. Only on battery terminals. Therefore, if you rely on the readings of a standard or self-installed voltmeter, check its readings with the voltage at the terminals.
The second important point is the multimeter. It must be calibrated and show real voltage. As a rule, many modern multimeters are tested and adjusted in production. But not all. But almost any device can be calibrated independently. As a last resort, check what it shows with some standard. As an example, you can contact an electronics repair shop. They always have a normal laboratory power supply and calibrated meters.
The last important point is the current load on the on-board network. This has already been discussed above. The reference voltage of the vehicle's on-board network should be measured with the consumers turned off. The issue of voltage drop under load is another topic. Here we consider exclusively low voltage under all the above conditions.
