And the subsequent start of the motor. During the engagement with the flywheel (braking moment), the car starter takes on an electrical current of about 350 A.
This device is designed for a short work, the long-term rotation of the starter significantly reduces its resource. Note that a fully working engine starts from the starter almost immediately, without the need to rotate the crankshaft. In the cold season, it is allowed to 2 attempts to start from the starter.
After turning the ignition key starter clicks, the motor starter does not spin
If the engine does not start from the starter, then the likelihood of various faults of this device is high. One of the frequent breakdowns of the starter is that the starter snaps or buzzes, but does not twist the engine. In other words, the driver turns the ignition key and hears distinct clips or a starter hum instead of the start of the motor (the crankshaft from the starter does not spin). Next, we consider the main reasons why the starter clicks, but the engine does not scroll.
Clicks that the driver hears when trying to start the engine, are a clicker of the traction starter relay. The specified starter relay constructively includes two types of winding. One of the windings is called retractor, the other received the name of the holding.
Clicking starter at startup means that clicks come from a traction relay. This is happening due to the fact that the retractor winding performs the relent core drawing, but as a result of a reduced voltage on the holding winding, the core is released.
The longer the key in the ignition lock is held in the start position, the more times the pulling winding will draw the core, and the retaining winding will be released.
Such a malfunction is accompanied by the specified starter click, which is actually clicking the traction relay. We add that the traction relay (retractor) has a similar design and the principle of operation on most vehicles regardless of the brand and model of the car.
The starter clicks or buzzes, but the engine does not grab: the main causes of malfunction
If a malfunction occurs, which manifests itself as a starter click at the time of engine start, then the character of clicking may indicate the causes of the breakage. In the event that the trailer starter relay clicks constantly:
- the battery is discharged, it is necessary to check the charging current;
- you should check the tightening of the battery terminals;
- there were problems with the "mass", it is required to check the place of contact of the mass with a body or internal combustion; it may take the implementation of additional revenue;
If the starter clicks only once and does not twist the engine, then the following may be:
- insufficient attachment of the traction relay to the starter case;
- there was a burning of contacts in the starter traction relay;
- the malfunction is associated with the bad contact "Mass";
- there was a breakdown of the starter;
In the event that checking the attachment of the traction relay did not reveal deviations from the norm, then the starter relay should be removed for verification. The collapsible relay means after disassembling the device, it is necessary to clean the power contacts. Inspecifying traction relay is subject to unambiguous replacement when the breakage is detected.
The lack of faults of the traction relay starter will indicate that further it is necessary to remove the starter itself for detailed diagnostics. Note that the starter clicks, but does not twist both due to the breakdown of the starter relay, and as a result of its own faults. The most common are:
- the power wire, which comes from the starter winding to the traction relay, can be burned off;
- there was a critical wear of the brushes of the starter. In this case, the brushes require replacement;
- anchoring anchor arises due to the wear of the starter bushings. Starter bushings will be replaced;
- there is a closure of the winding anchor winding, as well as a break or closure of stator windings;
You should also separately mention such an element as the Bendix starter. Bendix can be deformed or takes a breakdown of Bendix drive plug. Another problem that is associated with the Bendix starter is damage to his teeth. Bindix's teeth tooth means that the device cannot engage with teeth on the wedge of the flywheel.
Another Bendix is \u200b\u200bassociated with the core of the retractor by means of a special fork. The lack of the engagement of Bendix with the teeth of the wint of the flywheel means that in this case there will be no full drawing into the winding of the traction relay at the time of inclusion. As a result, the so-called "Pynet" will not be able to cross the power contacts relay to supply the power to the starter electric motor.
How to check the traction starter relay
Check the traction starter relay with your own hands with the help of an autootter. To do this, you first need to measure the stress from the battery on the starter contact. After that, the probe tester is connected to the starter output, after which it is necessary to turn on the ignition and rotate the key to the "Start" position.
During measurements, you need to pay attention to the following: if the input measurements show a voltage that corresponds to the normal charge of the battery, but during the operation of the traction relay at the output, the voltage drops by 2-3 times, then the likelihood of burning the power contacts of the retractor relay is high.
If the traction fails, the starter click, which does not twist the engine. The fact is that the burnt contacts cannot transmit voltage completely due to insufficient contact.
If the input voltage corresponds to the voltage of the charged battery and the similar voltage indicator is noted at the output of the traction relay, then the contacts of the traction relay are in perfect order. This suggests that the breakdown occurred at the starter. In the first case, the trailer relay should be disassembled, after which the contacts should be cleaned, as well as clean the seaming plate. Inspection traction relay should be replaced with a new or obviously good device. In the second case, you will need to remove the starter for detailed diagnostics and detect device malfunctions.
