Advice 1: How to check starter relay

Every motorist at least once in their life been in a situation when the beloved machine has ceased to submit life signs. This can occur not only with the old car but with any car - the starter may not "spin", can click on empty retractor relay. Because there are absolutely reliable cars, sooner or later, components and assemblies wear out and require inspection, repair or replacement.
How to check starter relay
You will need
  • power supply 12-16 V or 24 to 32, wire
Instruction
1
Remove the car starter from the engine. To check out the retractor relay starter, connect the output retractor relay "50" with the positive terminal of the battery, and the housing of the starter with the negative. A healthy traction relay of a starter the anchor will push the drive gear out the window of the front cover with a distinctive click. Retractor relay performs two important functions. With a lever actuator (plug of the starter) with one-way clutch causes an engagement of the latter with the engine flywheel of the vehicle, and closes the contacts on the front side, thereby providing the current flow of the circuit to the stator of the starter. The typical failure of the retractor relay - scorching contacts, jamming of the armature due to corrosion or dirt, breakage or burnout of the winding.
2
Install between the gear and the restrictive ring gasket with a thickness of 12.8 mm and turn on the relay. Take the device and check the switching voltage of the relay. It should not exceed 9 V At an ambient temperature of 20±5° C. If the voltage does not match, it indicates a fault or a relay, or drive.This validation scheme is applied for starters, the ST-221 manufactured up to 1983, when he established a single traction relay. Have a starter with such a relay should also test the strength of the current. It should not exceed 23 A.

Advice 2: How to disassemble the retractor relay

Sometimes, when the engine is started, the trigger circuit of your starter closes as expected, the retractor snaps and he begins to spin, but one gets the feeling that if he does not have enough current. What causes can be, and if it is connected with a retractor relay, it is possible to disassemble it?

How to disassemble the retractor relay
Instruction
1
The reasons for this phenomenon can be contacts attaching the power wires on the back side of the pull-in relay, which is oxidized, or burnt inside the retractable. As well as worn down starter brushes.
2
To thoroughly understand and investigate the cause, first remove the starter. If you are uncomfortable to Unscrew the third position with open end wrench the bolt from the clamp of the starter, take the head on 13, extension cord, and key drive. Although it is possible you will have to remove the retractor relay without removing the starter from the car.
3
If you took it, then on the cover of the housing and the retractor make marks with a pencil so that when you fold you do not have any problems.
4
Then remove the retractor relay and disassemble the starter. So you can be sure that the brush is all right, to the critical 10 mm, they still fall short.
5
If you have removed the starter, disassemble it completely, do your due diligence and brush. You can use a lithium grease and graphite.
6
It is considered that the pull-in relay is a sealed. The cover of ebony you can Unscrew the two screws, but it doesn't come off as preventing two soldered wires. But you remove the two screws under the cross and respeite contacts soldering iron. Only not to damage the sealing gasket carefully with a thin screwdriver podavaite cover. Do this very carefully. And it easily comes off.
7
After parsing the lid you will find out the true cause of the defect. If burnt contacts retractors, they must be carefully cleaned. Repeat this procedure, even if they're right, but there are only slight traces of erosion. And even if there is no obvious traces of dirt on the contact group, possibly in poor condition is not power contact.
8
Carefully spend the build stage of the site. After all, in a strong tightening the nuts on brass bolts can damage the cover. If this trouble happens, seal the crack with epoxy, and fasten fiberglass. Although this is, of course, a temporary measure.
9
Spend the rest of the Assembly in the reverse order. And after starter checks for serviceability be sure to liberally lubricate all external contact with petroleum jelly so they don't oxidize.
Note
Retractor relay 2110 provides remote on starter motor and serves for the entrance of the meshing pinion of a starter with the flywheel ring. The principle of operation of the retractor relay is based on electromagnetism. Replacing the retractor relay. The retractor relay is under the hood and then the starter. Disconnect battery negative terminal. In the lower part we find the starter.
Useful advice
Most importantly, with caution to the removal of the cover, the gasket between it and the housing, the retractor relay does not like mechanical interference, not damage it. Faults that lead to replacing the retractor relay starter VAZ 2110, are fairly common. The most common combustion coil windings, as often and burn out the contacts inside, but most often relay refuses to work for the most trivial reason.

Advice 3: How to connect a relay to the starter

Normal operation of the vehicle is impossible without well-organized system start-up. When adjusting the system electric start engine, you should observe the correct connection of batteries in a circuit containing a starter and the traction relay. Connect the relay to the starterand the regulation require deliberate and unhurried action.
How to connect a relay to the starter
You will need
  • elements the start system of the engine;
  • - battery;
  • - the probe.
Instruction
1
Understand for themselves the system of electrical starting of the engine and the manner of its operation. The structure of the device included the battery, starter, traction relay, ignition switches and lock the starterand connecting the wires. When you turn the ignition key current from battery goes to the coil of the traction relay starter. The anchor of the relay lever and the drive clutch shifts, and the drive gear is mated with a gear wreath of a flywheel. This leads to short contacts and activate the motor starter.
2
To adjust the clearance between side gear and focusing disconnect the wire winding from the output of the traction relay, designated by the letter “M”. Connect the battery designed for 12V, to terminals “S” and “M”. The gear actuator shall move to the position of engagement. Using feeler gauge, check the clearance between the stop and the end face of the gear. If necessary, adjust by installing/removing spacers between the relay and the cover on the drive side.
3
To check pull-in winding of the relay connect the components to the starter motorfrom as indicated in the figure. The wire winding should be disconnected from the output, marked with the letter “M”. The battery is connected to the correct conclusions similar to the previous description. The gear is the normal retractor winding of the relay will move to a position of engagement.
4
To test the restraint winding of the traction relay, single output battery connect to the output "S", and the second to ground. The wire winding from the output “M” of the traction relay disconnect. Check for a faulty relay. If the gear repeatedly advances and returns, this indicates a breakage in the coil, and working on hold. Replace the traction relay.
Useful advice
In order to avoid burning out the winding check need as quickly as possible, but no more than ten seconds.
