The purpose of writing this text is to warn car owners against one common mistake. When the key is turned to the START/KRANK mark, the starter does not turn, and then they try to close the power terminals directly. Having opened the hood and reached the starter, they see two copper taps - they are closed. In this case, the electric motor is activated, but the solenoid relay is not activated, and the freewheel bearing remains in place. In reality, power taps cannot be shorted! We will talk further about how to properly close the starter with a screwdriver.
Other reasons why the car won't start
The role of the starter in the engine is to spin the crankshaft. It creates the necessary torque and compresses the mixture of fuel and air.
Due to the fact that the starting device does not act alone, but in conjunction with other components and assemblies, the following factors may be the source of problems:
- insufficient voltage in the battery;
- complete loss of battery charge;
- destruction of wiring or contacts;
- the appearance of malfunctions in the ignition switch;
- oil with non-standard characteristics;
- atmospheric corrosion of some parts of the conductive circuit.
Ways to start a car without interfering with the system
First of all, it is necessary to identify the reason why the starter fails. If the power unit refuses to work due to failure of the solenoid relay or starter winding, then you can try to start the car with a pusher or by towing.
We recommend: Replacing the heater fan of a Chevrolet Niva car with your own hands
VAZ 2114 or VAZ 2110 is easily started using a pusher. The light weight of the car allows you to try to start the car with just a couple of assistants. Resting against the car from behind, they must try to accelerate it, and while driving, the driver turns the key in the ignition and turns on first gear.
The time it takes to start the engine depends on the speed of the car.
If this method does not allow you to obtain the desired result, then you must try to tow the car. This will require the help of other drivers. A special cable is attached to the car, with the help of which towing occurs.
This method is analogous to pushing a car, but its efficiency is much higher.
Many motorists easily agree to help in a difficult situation, so there is no need to be afraid of stopping the car even on major highways.
When starting the engine by towing, it is worth remembering that the car is accelerating and when stopping it is necessary to ensure the safety of the car in front, but the engine cannot be turned off.
Starter diagnostic methods
Certain problems with the starter allow it to function while the engine is running. As for spinning up a massive flywheel on the first try, this turns out to be impossible.
However, you should not play the lottery. If the engine starts successfully, you should immediately deliver the starter to professional auto electricians so that they can diagnose the unit and identify the real cause of its breakdown.
Causes of starter malfunction
If, when you try to turn on, the starter still shows signs of life, for example, you can hear its armature spinning idle or an unpleasant sound is heard when the Bendix overrunning clutch slips, then the failure of the unit is mechanical in nature. That is, there is a failure of the fork, overrunning clutch or planetary gearbox (if any). In this case, you will not be able to start the car if the starter does not work. It will have to be removed and repaired, and the launch will be carried out “from the pusher”.
Car starter circuit
If the flywheel turns too slowly, it is a sign that the armature is touching the stator. As motorists say - “shoes”. This happens due to wear of the armature sliding bearings - bushings. Moreover, if you operate the starter for a long time with worn bushings, then the armature winding plates, constantly “clinging” to the stator, will begin to shift, damage the winding wires and a short circuit will occur. In order to narrow the scope of troubleshooting when it is associated with a power supply failure, car repair shops often use this method to start the starter, such as shorting the terminals of the “positive” wires connected to the solenoid relay. If the attempt is unsuccessful, then the fault should be looked for inside the starter. Its cause may be:
- Worn or stuck brushes.
- Broken wiring in the solenoid relay.
- Broken stator or armature windings.
- Burnt contacts of the solenoid relay.
The starter working as a result of such a “direct connection” will be a clear indication that the electrical circuit is broken outside the unit, that is, the following options are possible:
- Broken contact group of the ignition switch.
- Failure of the starter switch relay.
- Break or short to ground of the positive wires.
- A break in the “mass” wire of the engine or severe oxidation of its terminals.
This starting method is suitable not only for diagnostics, but can also help out in cases where there is no time to repair the car, but you still need to drive.
Direct closure of the starter
To close the starter directly, it is necessary to connect it to the battery or through contacts. Both of these methods are considered reliable, however, provided that the anchor remains intact.
How to check the solenoid relay
To check the starter solenoid relay, you need to connect the positive battery terminal to it , and the negative terminal to the device body . When the relay is working properly, the Bendix gear will move out with a characteristic click.
Checking the Solenoid Relay Using a Battery
The gear may not extend due to:
- burnt retractor contacts;
- jammed anchor;
- burnout of the starter winding or relay.
Shorting terminals with a metal object
If a fault is detected in the traction relay, it is necessary to use the direct closure method using an iron rod of suitable length. Most often in a garage this becomes
- screwdriver;
- wrench;
- improvised metal pin.
The fact that there are problems with the retractor can be guessed by the specific clicking sound when turning the key in the lock. At this moment, the starter is unable to start rotating the crankshaft, since the bendix teeth simply do not engage with the flywheel crown.
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).
A handy alternative to a traction relay
If you close the starter terminals, you will be able to direct the current directly to the electrical windings. In this case, a screwdriver or other improvised device will perform the function of a traction relay.
It is very important to put the car on the handbrake and at neutral speed before carrying out such manipulations, otherwise severe injury or death of the mechanic is likely due to the vehicle getting out of control.
Recommendations
Systematic starting directly can lead to malfunctions in the vehicle wiring. This type of connection can be used one time. To correctly close a knot directly, you should follow several rules:
- Select a metal product with a large cross-section. This will prevent the part from heating up and causing a burn.
- It is necessary to close the nuts, not the threaded surfaces. Violating this rule will damage the threaded connection.
- When connecting, do not touch other parts. The mass of a vehicle is its body. Connecting pads and other parts will result in a short circuit.
- Turn off the power immediately after starting the power plant. Untimely shutdown will cause the drive gear (Bendix) to break.
Taking into account these recommendations, you will be able to correctly close the electric starter with a screwdriver or other object.
Safety rules for closing the starter with a screwdriver
You should also ensure that the tool you use is equipped with a carefully insulated handle and that its metal part is not thin or flexible. It is automobile screwdrivers that fully meet the listed criteria.
If the decision was made to use a pry bar or wrench, then it is strictly forbidden to begin work unless a thick layer of insulating tape has first been applied to the place of the hand grip. It is strictly forbidden to short-circuit terminals B and S, M and B.
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.
Starter short circuits on VAZ cars
Owners of VAZ models should take into account the following nuance. On the nine, ten and 14th models, to bridge the starter with a screwdriver, you will have to do the following:
- remove the air filter;
- separate the chip that is laid on the contact group.
After successfully starting the engine, the listed components are reassembled.
No second attempt allowed
A significant disadvantage of this method of restoring the starter’s functionality is the real danger of burning the car’s ignition coil. It is for this reason that it is extremely undesirable to try to perform this combination a second time.
It's better to limit yourself to one attempt. If it is not successful, then the source of the problems must be carefully looked for in other systems and units.
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!
Danger of screwdriver sticking to starter terminals
You should also be prepared for another extremely unpleasant scenario. At the points where the iron rod comes into contact with the terminals, no matter what the current strength in the vehicle network, a current of up to fifty amperes is created.
For this reason, the screwdriver pin is quite capable of both sticking to the contacts and striking sharply into the palm. In such a case, it is necessary to reset the negative terminal using an open-end wrench without unnecessary emotions.
Our advice
- First of all, do not allow short circuit or any other accidental short circuit of power contacts that are different from the control terminal and spade contact.
- Taking into account that direct access to the starter is often provided at the bottom, you must be prepared for the mandatory removal of standard or other protection.
- On many vehicles, the control terminal is similar to a threaded outlet.
- At the end of starting a car engine, you need to check the fuses separately, since it happens that they burn out due to errors.
- Since the traction voltage is 30-50A and higher, the connection points may stick.
- Drivers of older cars in which the switch does not control the voltage supply to the coil should be aware that when the starter is shorted, the coil may stop working.
Connecting the starter directly to the battery
In order to make a direct connection between the starter and the battery, it will be necessary
- a piece of copper wire;
- alligator clips;
- flat configuration plug.
The listed devices become components of a carrier that allows you to start the motor. Such a self-made accessory should be connected to a conductive cable going to the starter. It is equipped with a connector to which the carrier should be connected.
What to do if closing the starter did not help
- The car is placed at neutral speed;
- the ignition is turned on;
- The crocodile starts on the positive terminal of the on-board battery.
If there are no other problems or doubtful aspects in the design of the machine, the starter should turn on. When the engine can be started safely, you must immediately reset the terminal from the battery.
The homemade carrier must be torn out from the place of fixation. The removed plug is returned to its original position.
The listed manipulations will not cause great difficulties, but in no case should you relax and act carelessly. Otherwise, there is an absolute danger of getting a serious burn or causing a short circuit.
Other engine starting options
The car enthusiast also has the following methods of starting the engine that do not require the participation of a starter:
- towing method;
- by pushing back or forward.
We must not lose sight of the fact that both of these methods are completely inapplicable for cars equipped with automatic transmission. Due to the specifics of this gearbox, such methods of solving the problem can lead to extremely unpleasant consequences.

Rules for pushing and towing a car
Pushing is especially popular among car enthusiasts. For its successful implementation, the participation of several healthy and strong men is necessary.
If the decision was made to tow, then this will require a very strong special cable. It clings to the towbar of the tractor, after which both begin to move. If there are no problems in the ignition system or engine components and assemblies, then it is highly likely to start.
Towing safety
- The towing vehicle should not start moving impulsively. The start should be extremely smooth and slow. Otherwise, there is a high probability of the bumper, towbar, or cable breaking off.
- The towed vehicle should not suddenly stop moving or simply reduce speed while the towing vehicle retains kinetic energy. Otherwise, the cable may become over-tensioned and break, which could result in the windshield breaking and fatal injury to the driver of the towed vehicle.
- After disconnecting the cable, under no circumstances should you turn off the engine, because then it may simply not start.
How to push a car
The widespread “pusher” is based on the rigid support of the hands of several men in the trunk or hood of a car. In this case, the gearbox lever should be set to
- second;
- fourth;
- or reverse gear.
To successfully implement such a plan, the car must be accelerated as much as possible. That is why it is advisable to try to start it with a pusher on a gentle slope. It is strictly forbidden to push the car in a place sandwiched by walls, garages and other barriers. This is a very dangerous type of launch, fraught with disability and death of assistants.
Preliminary diagnosis of the problem
Before closing the starter, a very important step is testing in order to determine the sources of possible malfunctions and try to correct at least some of the problems. The most serious damage is considered to be complete or partial wear of the bendix, deformed or completely burned out due to high temperatures, starter winding, lack of functionality of its relay and solenoid relay. If you notice at least one such problem, then you can try methods for starting an engine whose starter has actually failed. There are few options, but they are effective.
For example, the first method requires the help of several strong men, since you will have to accelerate the car by pushing from the trunk. At this moment, the driver must turn on the ignition key and shift into first gear. In general, the more actively the assistants push the car from behind, the faster it will be able to start. This method is the most popular due to its simplicity.
Another method is towing. The essence of the action is that the “leading” car tows the car with a non-working starter over a certain distance, using a strong cable. However, when resorting to this method, you need to be extremely careful, since after successfully turning on the engine, the car will begin to accelerate and should be controlled. When the “leading” car slows down, you need to brake to avoid a collision.
I advise you not to turn off the engine when you stop the car in order to get out and unhook the cable.
There are other methods that involve direct intervention in the insides of the machine. This refers to a way to close the starter using a screwdriver.
