1. Disconnect from the valve a block with wires. |
2. Connect an ohmmeter to contacts of the valve and measure its resistance, it has to be equal 22–30 Ohms. If resistance differs from specified, replace the valve. |
|
3. Check power supply of the valve. For this purpose connect tension indicator with a light-emitting diode to contact of 1 block disconnected from the valve and "mass" of the engine. Include a starter, the light-emitting diode has to burn; if does not burn, eliminate break in conducting. |
