The indicator of quantity of fuel

The scheme of an arrangement of the gauge of temperature of the engine

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

3 – the indicator of temperature of a cooling liquid.


For regulation of the indicator of quantity of gasoline to remove small nippers a black stopper (a black arrow) near to the button of dump of quantity of the passed kilometres. Now it is possible to adjust the indicator rotation of the adjusting screw (a white arrow) by means of face шестигранного a wrench.

Gasoline level is displayed on the instrument panel. Thus, the indicator of quantity of fuel is anything to others as the voltmeter full pressure to which arrives at the included ignition. That pressure was to constants, in an electric chain the preliminary voltage stabilizer about which we will speak still is connected.

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

Malfunctions

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

Regulation of the indicator of quantity of fuel

 PERFORMANCE ORDER

  1. To devastate a fuel tank to last drop.
  2. To pour in a tank exactly 4 l of fuel.
  3. To include ignition and to wait 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 to the button of dump of quantity of the passed kilometres and turn the adjusting screw a key for internal шестигранника.

Check of the gauge of the indicator of quantity 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 being under it.
  2. To connect an auxiliary wire in штекерный a 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 is perfectly in order. If there is no arrow movement, means, the gauge in a fuel tank is faulty.
  4. If the arrow remains in position «an empty tank», means, it is necessary to search for a cause of defect in conducting, in a voltage stabilizer or the device. The gauge in this case most likely is perfectly in order.
