I am having trouble with my 75 (milano) 3.0. It doesn't receive charging from the alternator. The alternator is rebuilt and tested so thats not the problem. It also has 0 ohm (contact) between the connector of D+ and on the Alfa Romeo Control.
In pursue of the problem I opened my Alfa Romeo Control unit, which had a loose component inside. It looks like a diode that has to be connected in the right direction.

Can someone look at their AR Control unit and see which way it is supposed to be mounted? It would be very much appreciated. I was thinking of just soldering it back on and hoping the charging problem would be fixed.
