A 61 with an alternator ??? are you sure you don't 't mean a generator Try posting a picture


The car has been upgraded with an Abarth engine and 5 speed transmission. Here is a picture of the regulator that is installed on car. It has a 12 volt charging system. I'm not sure if 12 volt is original.


Here is the alternator


The car is fixed. The charging system was wired through a relay and the relay was bad.
