3.2.9. Check electrically the operated engine stop valve

If the stop of the engine is impossible or the engine is not possible to start (lack of fuel in nozzles), then it is necessary to check a contour of electric power supply of the valve, and also resistance of its electromagnet.

1. Take the valve (it is necessary to use a key 8.0117 AE for electrically the operated Bosch valves).
2. Measure the electromagnet resistance (about 8 Ohms). If the measured value of resistance does not correspond to the above, it is necessary to replace the valve.
3. Install the valve supplied with a new round sealing ring and tighten the moment of 15 Roto Diesel or 20 Bosch.
