GENERAL INFORMATION

Numbers of contacts of a connecting block of the control unit


PERFORMANCE ORDER
1. To disconnect the central wire of a high voltage from the distributor of ignition and to connect it to "weight".
2. To disconnect a connecting block.
3. To connect the voltmeter to extreme contacts "1" and "3", to include ignition. The voltmeter has to show tension about 9 Century. Otherwise to check conducting.
4. To shift back a protective cover from a block, to connect the voltmeter to contacts "1" and "2" and to establish a block in a nest on the ignition distributor.
5. To uncover the distributor, the runner and the antidust screen.
6. To turn a cranked shaft of the engine so that teeth of an anchor (1) distributor did not block the sensor of the Hall (2). To include ignition. Tension has to be 4 Century.
7. To turn a cranked shaft so that one of teeth of an anchor was combined with the Hall sensor. Tension has to decrease to 0–0,5 V. Vyklyuchit ignition. If tension differs from set, to replace the Hall sensor.
8. To connect an ohmmeter to contacts "1" and "4", then to contacts "2" and "27" and, at last, with "3" and "25". Resistance has to be equal in all cases to zero. If resistance differs from zero, means in conducting there is a break.
