FUNCTIONAL DESCRIPTION (TD version)

When the key in the ignitions switch B1 is turned to the "START" position, it energises the winding of the electromagnet (pin 50) of the starter motor A11 and supplies (pin 30) the starter motor itself with current leading directly from the battery A1 thereby cranking the engine (in cars without ALFA ROMEO CODE, but fitted with car alarm, the starter motor supply "crosses" the theft alarm control unit N45 (pin B5 - B6) which cuts off the supply in the event of an alarm and the starting consent relay I10).

When the engine is running, the direct current generated by the alternator A3 (pin B+) is sent to recharge the battery A1; from chassis no..... via the branch terminal box G56 .

All the lines for supplying the various electric systems of the car branch from the terminal box G56 connected to the + terminal of the battery A1 (see "Supply").

When the alternator is not turning and therefore not charging the battery, an earth signal is sent from pin D+ to the instrument cluster C10 to turn on the corresponding warning light; once the engine has been started this signal becomes 12 V and the warning light goes off.
