GENERAL INFORMATION

Check of connection between contact of the sensor of a detonation and the block of cylinders of the engine

The sensor of a detonation finds a detonation in engine cylinders. The control system of a detonation is intended for reduction of a detonation during the operation of the engine. It allows to use the maximum advancing of ignition and to improve a general characteristic of the engine. The sensor of a detonation induces the constant tension which increases at increase in a detonation.

Check

PERFORMANCE ORDER

By means of an ohmmeter be convinced of lack of resistance between contact of the sensor of a detonation and the block of cylinders of the engine. Check that there is no connection between contact of the sensor of a detonation and the block of cylinders of the engine.
