The starter relay is the main element of this device

This article considers the starter, the device of this device.

A starter is an important mechanism for every car. This device is represented as a four-pole, four-brush DC motor. There is a starter on the right side of the cylinder block and it is fixed to the clutch housing by bolts.

The starter consists of the following parts:

• the body;
• Anchor;
• clutch overtaking;
• covers in an amount of 2 pcs .;
• electromagnetic traction relay.

Starter relay value

The traction relay of the starter is responsible for the input of the geardrive of this device into engagement, as well as for closing the stator power circuit and armature windings. In the cover of the relay there are bolts with contacts. One bolt is connected to the positive terminal of the battery, and the other to the stator and relay windings.

During the turn of the ignition key, the outputof this cover of the starter tag relay receives voltage, forming a magnetic field. Due to this, the armature is retracted, and the contact bolts are closed, affecting the drive arm. Then, in the interaction of magnetic fields, the starter and hub anchors begin to rotate, and the clutch rollers are wedged. The resulting torque is transmitted by means of the clutch itself and the drive gear to the flywheel crown. By exceeding the speed of the gears over the shaft of the starter armature, the clutch rollers are wedged, the torque is not transmitted to the starter armature shaft.

If you return the key to the first position, then the power circuit of the winding of the starter traction relay and the contacts will open. Due to this, the drive gear is disengaged.

How to check the starter?

A device can be tested withoutstand. For this procedure you will need a mite and a multimeter. First you need to put the multimeter in the voltage measurement mode on the terminals of the power supply. Thus the battery should be charged on 100% with density 1,28. Then you need:

1. See the voltage reduction when the headlights and dimensions are switched on. With normal battery performance, this indicator will drop to 12.4-12.5 volts.
2. Scrolling the starter. To do this, you will need an assistant, who, on command, will turn on the starter. When scrolling, the voltage on the battery should be at least 10.5 volts. If there is a sluggish rotation at the indicated voltage drops, then this indicator should be checked on the wires going from the engine case to the negative of the battery. Similar actions are carried out in relation to the plus wire.

It should be noted that starters with planetaryreducer with unscrewed candles, as well as starters without a reducer consume 20-30% less. If the cause is internal, especially if it is a starter relay, then this device should be disassembled in order to identify the existing defects. This procedure is better to entrust to specialized centers, since often self-disassembly of the starter leads to its complete replacement. Checking the starter can be carried out in garage conditions, because this process does not require special tools.
