Voltage stabilizer

On an underside of a combination of devices sideways on a small radiator the voltage stabilizer (arrow) is established.

On an underside of the block of a combination of devices by three bolts it is screwed small ящичек – a voltage stabilizer. Its problem – to supply indicators of temperature and quantity of fuel completely выравненным with pressure. Otherwise pressure fluctuations will lead to fluctuations of arrows of indicators.

If both devices behave «lines knows as» or at all show nothing, most likely, because of the stabilizer.

Voltage stabilizer check

PERFORMANCE ORDER

To remove a combination of devices, again to connect a wire.
To include ignition.
To connect the voltmeter between average and left contact of the stabilizer (if to look at a combination of devices from an underside).
The voltmeter should show 9,75—10,25 Century
If value of pressure leaves for these limits, means, the voltage stabilizer is faulty. If at all there is no pressure, it is necessary to check up food giving.
For this purpose to connect the voltmeter between average and right contact of the stabilizer. If it does not show storage pressure, means, it is necessary to search for rupture in conducting.
