2. Start the engine. Thus pressure can fall to 8 In (at external temperature + 20С).

3. Increase number of turns of the engine to 3000 rpm. Pressure thus should make 13.0 - 14.5 V.Eto specify in serviceability of the generator and a regulator. Pressure of the generator (onboard pressure) should be above, than pressure of the storage battery that in the course of movement it was charged.

4. Check up a regulator. For this purpose include a headlight and measure pressure at 3000 rpm. Pressure should not exceed more, than on 0.4 In the values, received at the previous measurement.
