Indicator of amount of fuel

Scheme of an arrangement of the sensor of temperature of the engine

1–signaling device contact «an overheat of cooling liquid»;
2–"weight" (case);

3–the indicator of temperature of cooling liquid.


For regulation of the indicator of amount of gasoline to remove small nippers a black stopper (a black arrow) near the button of dumping of number of the passable kilometers. Now it is possible to adjust the indicator rotation of the adjusting screw (a white arrow) by means of a face six-sided wrench.

Level of gasoline is displayed on the dashboard. Thus, the indicator of amount of fuel is anything other as the voltmeter full tension to which arrives at the included ignition. In order that tension was constant, in an electric chain the preliminary voltage stabilizer about which we will speak still is connected.

Movement of an arrow of the indicator of amount of fuel varies by means of contact to "weight". It is provided by the sensor of amount of the fuel which resistance changes in the big or smaller party depending on tank filling. Removal of the sensor of the indicator of amount of fuel is described in head the Fuel tank and the fuel pump.

Malfunctions

  • Too high or too low level: the voltage stabilizer (as it to remove, it is described at the beginning of head, in the section "Dismantling", or is incorrectly adjusted the indicator of amount of fuel (see the following section) is faulty.
  • Any indicators: the voltage stabilizer, or the sensor in a fuel tank, or the indicator is faulty.

Regulation of the indicator of amount of fuel

 PERFORMANCE ORDER

  1. To devastate a fuel tank to a last straw.
  2. To pour in a tank exactly 4 l of fuel.
  3. To include ignition and to wait for 2 minutes.
  4. The arrow of the indicator should stand now at the first big column of a red field of a reserve.
  5. If it not so, it is possible to adjust the indicator a small adjusting bolt at the left below on the device.
  6. For this purpose remove by means of small pincers a black stopper near the button of dumping of number of the passable kilometers and turn the adjusting screw a key for an internal shestigrannik.

Check of the sensor of the indicator of amount of fuel

 PERFORMANCE ORDER

  1. To cast away a covering of a luggage compartment, to turn off a black cover, to separate the multicontact tip which was under it.
  2. To connect an auxiliary wire in the shtekerny socket of a violet-black wire and to close on "weight".
  3. To include ignition for short time: if the arrow of the indicator completely deviates, means, conducting and the indicator as it should be. If there is no arrow movement, means, the sensor in a fuel tank is faulty.
  4. If the arrow remains in situation «an empty tank», means, the cause of defect should be looked for in conducting, in a voltage stabilizer or the device. The sensor in this case most likely as it should be.
