Fuel gauge
The device works in tandem with a sensor installed in the fuel tank. The same sensor also turns on the fuel reserve control lamp if 4-6 liters of gasoline remain in the tank. With a sensor resistance of 285-335 ohms, the needle should be at the beginning of the scale, with a resistance of 100-135 ohms, in the middle of the scale, and with a sensor resistance of 7-25 ohms, it should deviate to the end of the scale (mark 1). The sensor with an empty tank should have a resistance of 315-345 ohms; with a half-filled tank, 108-128 ohms, and with a full tank - no more than 7 ohms.
Speedometer
The device is checked by rotating its drive roller at different speeds. The calibration data of the speedometer are as follows: at a drive shaft speed of 500 min-1 speedometer readings should correspond to 30-32 km / h at 1000 - 60... 63.5, at 1500 - 90... 94.5, at 2000 - 120... 125.5 and at 2500 min-1 - 150... 156.5 km / h.
Oil pressure warning light sensor
The sensor is mounted on the oil filter flange. The sensor contacts should close and open at a pressure of 20-60 kPa.
Relay-interrupter of a control lamp of a parking brake
The RS-492 relay-breaker is suspended on wires on the left side under the instrument panel and serves to obtain intermittent burning of the parking brake warning lamp. The number of cycles per minute of turning on and off the relay-breaker at a voltage of 10.8 to 15 V and a temperature of -40... + 40°C should be within 60-120. The resistance of the breaker winding is 26 ohms.
