| 1. Remove the top casing of the engine (subsection 2.1 see). |
| 2. At engines of 1,4 l, 55 and 74 kw disconnect колодку with wires from the ignition module. |
| 3. Disconnect колодки with wires from atomizers. |
|
4. Connect the electric indicator of pressure with a light-emitting diode to contacts колодки 1, 2 first cylinders disconnected from an atomizer (3 – the indicator of pressure with a light-emitting diode). |
| 5. Turn the engine a starter, thus the light-emitting diode should blink. It means that a food on an atomizer moves. In the same way check up other atomizers. |
|
|
| 6. If at проворачивании the engine the diode does not blink, connect the pressure indicator to contact 1 колодки (2 – the second contact), disconnected from an atomizer of the first cylinder, and to "weight" (and – engines of 1,0 l, 37 kw and 1,4 l, 50 kw; – engines of 1,4 l, 55 and 74 kw). Turn the engine a starter, the light-emitting diode should blink; if does not blink, check up wires on breakage and short circuit. Similarly check up other atomizers. |
| 7. If breakage in wires is not present, check up resistance of atomizers. For this purpose connect an ohmmeter to contacts of an atomizer and measure resistance. For engines of 1,0 l, 37 kw and 1,4 l, 50 kw it should be 14–20 Ohm; for engines of 1,4 l, 55 and 74 kw – 14–17 Ohm (at 20 With, at the heated-up engine resistance above approximately on 4–6 Ohm). If resistance differs from specified, replace atomizers. |
