How to close the starter directly with a screwdriver and other methods

During the operation of a car, problems with the starter quite often arise. Moreover, even if the battery is charged and power comes to the starter after turning the key in the ignition, the device still does not work and the engine does not start.

In such a situation, there are only two ways to start the engine:

starting the engine “from the pusher”;
attempt to close the starter directly;

Although the second method is less common, in some cases this method is more “convenient”. The main thing is to know how to bridge the starter correctly to start the power unit. Read more in our article.

Why doesn't the starter work?

The car starter is actually an electric motor that is “attached” by its gear (Bendix starter gear) to the flywheel (flywheel crown), rotates the crankshaft and is then disconnected after the engine starts.

In this case, there are a number of reasons why the starter does not work:

problems with wiring and contacts;
the starter relay does not work;
The starter solenoid relay is faulty.
the starter winding burned out;
the overrunning clutch has worn out, etc.;

As a rule, the main and most common problem is the failure of the starter solenoid relay. If the retractor is faulty, the starter will not turn the engine. A problem with the retractor is indicated by a click that can be heard when turning the ignition key.

If the starter clicks, the relay is turned on, but the overrunning clutch is unable to turn the crankshaft. In the case when the starter does not work precisely for the specified reason, you can try to supply power to it directly (close the starter).

Self-diagnosis

In order to find the cause of a mechanism malfunction, you need to understand how it works, know how the starter is connected, and how to check all its elements for serviceability.

Trigger device

The device consists of a large number of parts, but its basis is:

electric motor;
bendix;
solenoid relay.

With the help of an electric motor, the energy received from the battery at start is transferred through the gear to the engine crankshaft. The starter is an electromechanical device, so it can have both mechanical and electrical faults.

How to close the starter

To close the starter, you need to connect the starter power contacts with a metal part of a suitable tool. This will allow voltage to be applied to the winding directly. To do this, you need an assistant who must turn the key in the lock to the “start” position.

In general, the process looks like this:

the car is put on the “handbrake”, the manual transmission is switched to neutral or the P mode is switched on “automatic”;
The contact plate is removed from the starter, after which the contacts need to be short-circuited with the tip.

In this case, it is important that a current conductor of suitable length and cross-section be used as a jumper. Typically, a screwdriver with a thick shaft or a wrench with an insulated handle is used for these purposes.

To understand how to close the starter with a screwdriver, you need to pay attention to the following:

you need to close the contacts of the power line precisely on the solenoid relay.
All actions should be performed carefully and carefully, without touching other elements under the hood;
Do not touch the starter housing with a screwdriver, etc.
after starting the engine, the screwdriver must be removed;

In this case, closing two power contacts on the solenoid relay with a screwdriver is similar to closing them from the inside with the relay armature. In fact, the operation of a retractor starter motor for connecting the electric motor is simulated. If the ignition is turned on, the starter will start working with such a short circuit and the engine will start.

Please note that when the contacts are closed there will be sparks, since the starter connection is direct. Another disadvantage of the method is that not all cars have direct access to the starter (it is impossible to close the contacts on the solenoid relay). After the engine starts, the screwdriver will need to be removed from the contacts, after which the starter will turn off.

If we take a closer look at the question of how to connect the starter directly, pay attention to the following points:

You need to find the control (pin that looks like a petal). Other contacts (one with potential +12 has a thick wire). Another contact is an electric motor contact. You need to close the control terminal (usually closed with a rubber cap) and the contact tab (usually closed with a plastic plug).

Some information about the ignition switch device

Lada Priora cars use anti-theft locks that block the next start of the starter and connect the key to the standard anti-theft system. The device is located directly under the steering wheel in a special way (four screws with tear-off caps that prevent unscrewing) and is fixed to the steering column.

The engine is started using a key that is inserted into the lock cylinder.

The device is powered by a battery, and a special relay marked “K4” is responsible for ensuring proper protection of the electrical circuit. The starter locking is achieved by a locking rod that is retracted and prevents the key from being removed in all its positions except the zero stage (position “0”). With one key position, only electrical circuits are activated. In a different condition they are different. For example, at the first mark, some on-board equipment is activated (windshield wipers, power windows, dashboard indicators, etc.), and the next time you turn the key in the ignition switch, an additional power circuit is activated, and the engine starts.

Connecting the starter directly from the battery

It happens that problems arise with the wiring or contact group of the ignition switch. In this case, the engine can be started by supplying power from the battery to the starter. To do this, you need a copper wire, a connector and an alligator clip.

The wire is soldered to the connector. Next, the power wire to the starter is disconnected, and a copper wire with a connector is inserted instead. Then the “crocodile” must be connected to the “plus” of the battery. If the starter is working properly and there are no other problems, the engine will start. After starting, you need to remove the crocodile from the battery terminal.

The main thing is to perform all actions carefully, connecting the starter directly to the battery. Do not short the wire with any elements under the hood. After starting the engine and removing the copper wire from the connector, the starter plug can be returned to its place. It is also important to remember that you should not connect the wires to the battery and the connector for a long time, so as not to drain the battery.

Disadvantages of the method

The main disadvantage of this method of starting the starter is that you can easily burn the ignition coil. That is why experts recommend carrying out this action only once. But sometimes the engine does not start using this method, so the reason lies much deeper.

It is also worth considering that in those places where the screwdriver comes into contact with the terminal, a current of up to 50 A is issued. It can easily become stuck, and it will also kick back into your hand; it can be quickly removed using an open-end wrench.

Recommendations

It is important to ensure that contacts other than the control terminal and spade contact are not short-circuited or accidentally connected.
Taking into account the fact that access to the starter is usually from below, you need to be prepared for the need to remove standard or additional protection
On many cars, the control terminal has the form of a threaded outlet (a nut is screwed onto a bolt), while the terminal is of the “petal” type.
We also recommend reading the article about what to do if the alarm blocks the engine from starting. From this article you will learn how to remove the engine blocking alarm if a failure or error occurs.
If there is such a possibility, it is better to close the contacts not with a screwdriver, but with a wrench that has a handle (the handle should be well wrapped with insulation).
After completing the process of starting the engine, you should check the fuses separately, as they can burn out if mistakes are made;
Considering that the traction voltage uses 30-50A and higher, the connection points may stick.
Owners of old cars, where the switch does not control the voltage supply to the coil, need to remember that when the starter closes, the coil may fail;

Scheme, theory and practice

Let's see what the wiring diagram of any electric starter looks like. Contact B is constantly supplied with voltage.

Starter and its external circuits

In the diagram we see three “positive” contacts and one negative (8), which is always connected to the body. What needs to be closed:

Before closing the starter, locate the S terminal. It is often made in the form of a petal;
How to distinguish contacts B and M: the first will have a potential of “+12”;
You need to close contact B with terminal S. This is done briefly and after turning on the “neutral”;
Contacts M and B cannot be closed.

What's the result?

As you can see, if the engine does not start, the starter may be the main cause of this problem. In this case, the culprit is often the starter solenoid relay or problems with contacts, wiring, etc.

We also recommend reading the article about why the starter clicks but does not turn the engine. From this article you will learn about the main reasons why the starter makes clicking noises but the crankshaft does not turn.

In any case, you need to know how to start the starter directly from the battery or by closing the contacts if the engine starting system has failed. However, it should be understood that connecting the starter directly is a last resort and is used only in emergency cases.

If there is such a possibility, it is better to refuse to try to start the engine from a pushrod in a car with any type of automatic transmission, and also not to try to directly connect or close the starter. In some cases, a short circuit of the starter or errors when trying to close the device lead to a short circuit, blown fuses, breakdowns of the vehicle’s electrical equipment, etc.

Finally, we note that knowing how to close the starter with a screwdriver to start the engine still does not solve the problem. First of all, this method may not be effective in many cases. For this reason, it is important to accurately determine the nature of the malfunction, and only then decide on which method to start the power unit.

Method for VAZ 2107

This machine has a starter that can be started using a special handle. To do this, insert it into the provided hole in the body and by quickly rotating the car the car should start.

In the end, I would like to add that all the described methods should be used when, for various reasons, it is not possible to get professional help or tow the car to a repair shop. Therefore, we strongly recommend that you contact professionals, and before solving the problem yourself, carefully study the problem that has arisen and its solution in order to further avoid negative consequences. Good luck on the roads!

Fuel equipment

The fuel circuit consists of a pump, fuel supply lines, a fine filter, and nozzles - sprayers.

Most often, the fuel pump fails for the following reasons:

Natural wear of the part;
Systematic refueling with low quality fuel, with a high content of chemical impurities;
Third-party mechanical damage to the pump housing, filter;
Short circuit in the circuit;
Manufacturing defect.

Do not rush to replace the pump with a new one; it is enough to carry out preventive maintenance on the existing one. This will save a lot of money on repairs.

The gas distribution mechanism (GRM), its basis is a belt that connects the generator, crankshaft pulleys, and camshaft.

Due to weakening of tension, a break, it is impossible to start the Lada Granta engine. Replacing the drive belt is not at all difficult; the task can be done by a car enthusiast without any skills.

It is enough to loosen the generator mounts, move the housing as far as it will go, and remove the belt. Reassemble the structure in reverse order.

Starting the engine while towing a vehicle

This is another common method for starting a car engine with a faulty starter.

Important! This method is not suitable for vehicles equipped with an automatic transmission, since due to certain features of its design, towing the vehicle is strictly contraindicated.

To implement this method, you will need a tow rope and another car. It is extremely important to strictly follow the following sequence of actions during towing:

the leading machine should start moving smoothly and start moving at low speed to tension the cable;
the driver of a towed car should not brake sharply;
after the vehicle starts, it will begin to accelerate sharply;
you should stop only after the leading car stops;
Do not turn off the engine while unhooking the cable, otherwise it may not start, and towing will be required again.

conclusions

Let's look at diagram 1 again. If the key is not turned to the Start label, terminal S is “hanging in the air.” This can be done for any car, even if the circuit has an additional relay. This means that it will not be necessary to disconnect the standard wire from terminal S... And in the case of a VAZ, the disconnection is carried out in order to gain access to the terminal.

We removed the filter, disconnected the plug, and tried to close it...

If the engine filter cannot be removed or access is blocked by the battery, we do it differently - we use only the crank.

It is better to close the contacts not with a screwdriver, but with any wrench (see photo). It is desirable that the handle be insulated.

12 Volt voltage is not dangerous, but errors can result in blown fuses. Good luck.

For those who do not understand everything: the filter must be removed from the mounts, but not from the “corrugation”. The filter housing is placed on the battery.

Hello dear forum users! Granta arrived with a complaint about poor starting in the morning. It starts only after being towed for about three kilometers. Then it starts with the key and continues like this all day. I connect with a scanmatic, 8 cells. ECU m 74CAN. I see errors on the channel bus: short circuit (+) to (-). Also, cylinders 1-4 are skipped and fuel supply is prohibited. I erase the errors and start it (yes, the car has a 4th generation LPG). While running on gasoline there are misfires in the 4th cylinder, on gas in the first. On gas, turn off. I understand that the 1st injector is flowing. I think that on gas it interferes with the operation of the internal combustion engine. The pressure in the ramp is 3.7. There was only one injector in stock, so I put it on the 4th. The gaps in it have stopped. But on gasoline it still works very poorly, when the speed increases, it sneezes as if there is not enough fuel. All parameters are normal. Again, I measure the pressure in the ramp during operation, at some point it drops sharply and the engine starts to shut down. I am changing the pressure valve in the tank. Left. In the morning, the same story was barely started again. What could be the reason? Yes, I opened the ecu completely, everything is clean. Comrades, more experienced diagnosticians, I ask for advice, maybe someone has had something similar. I apologize if there is anything wrong, but I couldn’t find anything like this on the forum.

Edited by: Grinius on 10-6-2018 20:58 The valves say they were adjusted a week ago, they thought it was because of them. Last night it was with me. On the first start in the morning it started and stalled. The second launch is generally zero. Errors 0, I reset the training, it starts, I don’t press the gas too confidently and it stalls. I start it up again, it idles and thrashes, I switched to gas and then I revved it up. Rail pressure 3.6 Well, I see there are no thoughts yet. He'll come again tomorrow. For now I think it’s the injector that is pouring and the gasoline gets to the lambda and the car stalls. Well, I don't know anymore.
