Modification of the PC-57 turn relay | Cheerful Pencil
Technical evolution, technological progress - all this is good and wonderful. But when you have reliable, albeit old, equipment in your hands, equipped with the simplest electrical equipment, it does not calm you down for long. The reliability of the same equipment drops significantly if its production itself is treated as a handicraft and carelessly.
The old T-40 tractor is minimally equipped and few people do not know this. You can install any electrical equipment on it, creating comfort in operation and providing full detail of the operation of the engine and the unit as a whole. Is this just for everyone?
Yes. It was possible to install any electronic breaker relay or contact-transistor turn relay from modern technology, but any type of electronics had to be abandoned. Owner's wish. Everything is minimal and simple.
We settled on one of the 1984 PC57s. The principle of its operation is very simple, but this simple work was not performed by this relay. I will dwell on this very briefly.
In order for the relay to operate immediately after voltage is applied to it, and for the operating periods to be the same, it is necessary that an electromagnetic field be present in the relay core with a force sufficient to reliably hold the moving armatures with commutating contacts to the yoke of the core.
The magnetic field in the relay coil is also present at those moments when its switching contacts are open, but it is so weak that it is not enough to attract the armatures to the core. In our case, the electromagnetic field was weak even when the contacts of the control pair were closed with a lowering resistance shunt.
The magnetic field of a coil depends both on the amount of current flowing through it and on the number of turns forming the coil itself.
Typically, for light signaling of direction indicators, two 21 W incandescent lamps are required, not counting repeater lamps. The control lamp does not count, since it operates from a different contact group of the relay and is not connected to the relay coil.
In our problematic case, the PC57 relay taken for installation refused to work even when connecting four 21 W lamps (4X21) and two 55 W lamps (2X55), not to mention the control lamp. But how will it work if the number of turns of the core coil is less than the calculated one? So we had to add the same number of turns of wire to the existing coil. Simple and accessible.

Turning relay VAZ 2101 replacement with an electronic relay.
If desired, you can replace the electromagnetic-thermal relays of the VAZ 2101 with an electronic relay used on VAZs of subsequent brands. The connection is made in almost the same way. In addition to the standard wires, it is necessary to add only one wire connecting the electronic relay to the vehicle ground. In this case, you can also connect an alarm button.

Relay under the hood
Several relay elements are located in the engine compartment.
Turn signal and hazard warning relay
The turn signal and hazard warning relay (RS-491) is located on the bulkhead under the instrument cluster.
Headlight and battery charge relay
Scheme
Purpose
- Battery charge indicator relay (PC-702)
- Headlight high beam relay (VAZ-21011 and BA3-21013)
- Relay for low beam headlights (VAZ-21011 and BA3-21013)
1) Relay RS-702 is used to turn on the warning lamp on the instrument panel when the generator voltage is insufficient to charge the battery.
2) Headlights. On cars 2101 and 2102, as well as 21011 produced before 1980, the headlights are turned on by a switch located on the steering column when the exterior lighting switch is on. On cars 21011 produced since 1980 and on cars 21013, the headlights are turned on by the same switches, but through auxiliary relays.

Turning relay malfunctions and ways to eliminate them
Turn relays of all types have fairly high reliability, but these components are not immune to breakdowns. Typically, the failure of this relay makes it impossible to turn on the direction indicators, or disrupts their operation - they may be constantly on, blink too quickly or too slowly, etc.
The turn relay is a non-repairable part - if it malfunctions, this relay is simply replaced with a new one. Today, the price of VAZ turn signal relays is very affordable, so many drivers take them for future use, and in the future there are no problems with repairing and finding this component.

Electronic relay: circuit and principle of operation
The design of the electronic rotation relay consists of two main parts. From a standard electromagnetic relay that performs switching to an electronic key that provides a certain frequency of operation of this device.
The nichrome cord has been replaced with an electronic key. With its help, voltage is applied and removed from the winding of the electromagnetic relay at certain intervals. The key is built on microcircuits or discrete elements. They are components of the main generator and control circuits.
The operating principle of an electronic relay is very simple. When voltage is applied to the relay, the master oscillator is activated. With its help, control pulses with different frequencies are generated, which enter the control circuit. With the help of pulses, the current flowing through the coil of the electromagnetic relay is supplied or interrupted. Such actions also cause the anchor to retract or sink. As a result, the contact groups close or open at a certain frequency, which gives the same blinking as indicator lights.
All electronic elements of the relay are mounted on a separate board. An electromagnetic relay is located above the board. Both are housed in a plastic case. The contacts are thrown out from below or to the side. There are holes and tabs for bolt connections to secure the housing.
Each electronic rotation relay has undeniable advantages over other designs. High-quality and technologically advanced devices manufactured on the basis of modern circuits and characterized by increased reliability have proven themselves. The technical characteristics of these devices remain unchanged regardless of their service life.
DIY turn relay
Sometimes situations arise when the standard turn signal relay fails and a new device cannot be purchased. In such a situation, you can try to make a turn signal relay with your own hands to provide the car with the necessary signals. The simplest electronic devices that you can make yourself are simple and easy to use, operate smoothly and reliably. High precision is achieved through the use of PWM controllers used in all circuits.
The simplest replacement for an electromagnetic relay is designed for a maximum load power of 150 W. It is connected to the positive air gap. If the IRFZ44 field switch is replaced with the IRF3205 model, 200 W can also be connected. This simple circuit guarantees high accuracy. The blinking frequency does not depend on the power of the lamps, so LED, halogen and other lamps can be included in the circuit.
The blinking frequency is directly related to the capacitance of the capacitor. As the capacity increases, the indicator will blink less frequently, and conversely, decreasing the capacity will cause it to blink faster. The low-power 1n4148 diode can be replaced with any similar element. When the circuit reaches 80 W, a small amount of heat is observed in the FET area. This means it is ready to use.
There is another simple gear shift relay circuit with a coil - simple, reliable and inexpensive. It is capable of turning on both conventional and LED lamps and is designed for a voltage of 12 V. The contacts are connected according to the principle of a regular switch, that is, in series with the light bulb. The LED is installed in the circuit as an indicator during commissioning. The device parameters are regulated by changing the resistance of the resistor.
