Features and diagrams of light direction indicators GAZ-66 and GAZ-53
The turn signal connection diagrams are shown in Fig. 1 and 2. The sidelights and rear lamp are switched on with a switch of type P105 on a GAZ-53A car and P118 on a GAZ-66 car. The operation of the switches is checked using test lamps according to the diagrams shown in Fig. 151 and 152.
In the off position, lamps 4 and 5 should light up. When the right turn is turned on, lamps 4 and 6, and when turning left, lamps 3 and 5.
If on a GAZ-53A car the switch does not turn off after the car exits a turn, adjust the position of the switch. To do this, loosen the two screws securing the switch to the bracket and move the switch until the rubber roller does not touch the steering wheel hub in the off position (there should be a gap of 2 - 2.5 mm).
When the switch is turned on, the roller should be firmly pressed against the wheel hub.
Every 25,000 km of vehicle mileage in the P105 switch, lubricate the roller axis, the lever axis and the lever plate that presses the roller. The direction indicators light up with a flashing light (70 - 100 flashes per minute). This is achieved by including a PC57 type breaker in the electrical circuit of the direction indicators.
Let's take a closer look at the design and operation of turn signal lights:
The most widely used are turn signal indicators with an electromagnetic-thermal current interrupter - RS57, RS57-V, designed for 12 V, and RS401 - for 21 V.
Turn signal device. A winding consisting of 50 turns of PEL wire with a diameter of 0.75 mm is placed on the steel core 9 (Fig. 3). The core is rigidly connected to bracket 11. The breaker winding is connected in series with warning lamps 16 or 17 located in the rear light and sidelight, and when using PC57 V, with warning lamp 12 located on the instrument panel in the driver's cabin. Steel anchors 4 and 10 are welded to the core
In the non-working state, contacts 5 are opened by the force of the stretched nichrome string 3, and contacts 6 are opened by the tension of the bronze plate 8. All contacts of the breaker are silver.
The lower end of string 3 passes through glass bead 2 and is thickened by fusing solder. The bead insulates the string from the bracket.
The resistor has a resistance value of 18 Ohms, made of nichrome conductor.
Normal operation of the RS57 breaker is ensured by simultaneously turning on two signal lamps of 21 light, and the RS57-B of two signal lamps of 32 light and one control lamp of 1 light. If one of the signal lamps burns out, the current strength decreases, as a result of which the blinking frequency of the lamps significantly increases, and in the circuit with the PC57 relay, the control lamp does not turn on.
Turn signal operation. When the signal lamps are turned on, the current from the battery will pass through the ignition switch 13, armature 4, string 3, resistor, winding, switch 15 and to the lamps (see Fig. 3). The current path in the diagram is indicated by arrows. The filament heat will be small.
The current passing through string 3 will cause it to heat up, as a result of which the string will lengthen and its tension will decrease.
At this time, the steel armature 4 will be attracted to the electromagnet core and the contacts 5 of the breaker will close. Closed contacts 5 bypass the resistor and string 3. The current strength in the lamps will increase and their filaments will glow with full incandescence.
Interruption of the current in the string is accompanied by its cooling and reduction in length. The string is stretched again and opens the contacts, after which the process is repeated. The vibration frequency of the contacts is 60 ÷ 120 openings per minute. Periodic closing and opening of the control lamp 12 circuit in the PC57 is ensured by the operation of contacts 6.
At the moment of closing contacts 5, the current strength in the electromagnet winding increases, so the core is magnetized more strongly and, attracting the steel armature 10, ensures the closure of contacts 6. In this case, the test lamp turns on at the full voltage of the current source and burns at full intensity. After contacts 5 open, due to a decrease in the current in the electromagnet winding, the magnetization of its core decreases, and then, under the action of the elastic bronze plate 8, contacts 6 open and turn off the control lamp circuit.
