| 1. To put forward on itself a combination of devices, having disconnected only a cable of a drive of a speedometer and a vacuum tube (Pads with wires not to disconnect) (subsection 12.1.5.15 and subsection 12.1.5.15 see). |
| 2. To connect a wire to "the minus" plug of the storage battery. |
| 3. To connect the voltmeter to contacts of "input" and "weights" of a voltage stabilizer from an underside of a combination of devices. |
| 4. To include ignition and to check up pressure. It should be equal to pressure of the storage battery. If the measured pressure is considerable below pressure of the battery, in a stabilizer feed circuit there is a breakage. |
| 5. To connect the voltmeter to "exit" and "weight" contacts, to include ignition and to check up pressure. It should be 9,75–10,25 V.Esli the measured pressure differs from specified, it means that the voltage stabilizer is faulty also it it is necessary to replace. |
| 6. To establish a combination of devices upside-down. |
