Description - HORNS - Alfa Romeo GT 1.8 T.SPARK
The car is fitted with a horn system which consists of two horns with different tones: a high tone and a low tone horn. Both horns are activated simultaneously.The horns are operated by pressing the sides of the steering wheel cover (around the Air Bag).The horn circuit is protected by a special fuse and controlled by a specific relay located in the engine compartment control unit.For safety reasons, the horns can be operated at any time, even when the key is turned to OFF (or removed).
Functional description - HORNS - Alfa Romeo GT 1.8 T.SPARK
The system for the horns is supplied through the horn relay T3 of the engine compartment control unitB1 from the direct line from the battery through the fuse F10 located inB1.The relay coil is energized by an earth signal when one of the steering switches is closed; these switches are connected via the clock spring to the stalk unitH5. The relay thereby supplies the high tone hornP10and the low tone hornP11.The connection for the horn contact is via the clock spring connectorD47, which also transmits the signals for the driver''s Air Bag and the steering wheel controls (for radio and telephone).
