Alfa Romeo 155 Starting and Charging Circuit Diagram

When the ignition key is turned in switch B1 to the STARTING position, it activates the coils of the solenoid (pin 50) of the starter motor A11 and with the voltage coming from the battery A1 (pin 30) supplies the actual starter motor, thus starting the engine.

Note: in vehicle equipped with an anti-theft device the power supply to the starter motor (ignition key in the STARTING position) crosses the anti-theft device control unit N45 which cuts of this power supply in the event of an alarm.(click image to enlarge)








The DC current generated by the alternator A3 is sent to the battery A1 passing through motor A11.

All the power supply lines of the various electrical system on the vehicle start from the branch terminal board G56 connected to the + terminal of the battery A1.

When the alternator does not turn and therefore the battery is not being charged, an earth signal is sent to the instrument panel C10 and illuminates the relative warning light. When the engine is started this signal becomes 12V and the warning light goes out.
