Description of operation

DESCRIPTION OF OPERATION

Turning the ignition key of switch H1 to the end position (IGN) the electromagnet winding is energised (pin 50)by starter motor A20. This supply comes from the battery through the line of maxifuse IGN of B5.

In the automatic clutch version, this signal passes through the startup inhibition relay J81 : this is energised by the automatic clutch control unit M85 that supplies the consent signal from pin 25.

Pin 30 of A20,the actual motor, is powered with the voltage coming directly from battery A1.

The direct current generatedby the alternator A10 (pin B+) is sent to the battery A1, passing through maxifuse of B5.

When the alternator isnot in rotation, and does not recharge the battery, an earth signal is sentfrom pin D+ to cluster E50, pin 6 of connector A.

Cluster E50 receives ignition switch power supply (INT)to pin 5 of connector A of the line protected by fuse F22 of junction unit B1: when this signal arrives, the generator warning light switches on. With the engine running this signal becomes 12 V and the warning light switches off
