Index of level of fuel

Fig. 3. Scheme of verification of the index of level of fuel

1–X1 socket;
2–storage battery;
3–MLT-2 resistor (resistance 330, 118 and 11 Ohm);
4–X2 socket.

The index of level of fuel 32.3806 works together with the sensor 5412.3827 established in a fuel tank. The sensor represents a rheostat with the resistor from a nikhromovy wire. Mobile contact of a rheostat moves the lever with a float. On the end of the lever there is the additional contact closing a chain of a control lamp when in a tank there is a reserve stock of fuel.

Serviceability of the sensor of the index of fuel can be checked an ohmmeter.

Given for check of the sensor of the index of level of fuel

Amount of fuel in a tank

Resistance of the sensor, Ohm
Empty tank
315-345
Tank half
108-128
Full tank
6–16

The faulty sensor is replaced (see. Removal of the sensor of the index of level of fuel and toplivozabornik).

For check of the sensor of the index of level of fuel we remove a combination of devices (see. Removal of a combination of devices, replacement of lamps). We collect the scheme represented on fig. 3.

Consistently changing resistance, we carry out index tests. At resistance of 330 Ohm the device should show an empty tank, at 118 Ohm – a tank half, and at 11 Ohm – a full tank.
