How to hook up a Milano alternator
I have always been a 4 cylinder kind of guy. However, I am building
up a '66 Giulia Sprint GT, and my Alfa buddies have talked me into
1) replacing the generator with an alternator, and 2) as long as I'm
modifying the charging system, going with a 65A Milano/GTV6
alternator, rather than the 35 (?) amp unit that came on the 4
cylinder Alfas from the 1970's. Also, the Milano/GTV6 unit has
an internal regulator, resulting in less wiring/stuff underhood.
OK, so what are the connections on the thing? What I bought
through EBay (from someone locally, by the way) is a Bosch
0 120 489 715 * 716. K1 - 14v 65A -21. It basicly has three
connectors on the back:
A big 6mm stud marked "B+" that seems as if it ought to
be connected to the battery "+" terminal, yes?
A spade connector marked "D+". Hmm, that one is a
mystery. Maybe to the "idiot" light? And if so, I presume that
the other end of the idiot light goes to the ignition switch.
A spade connector marked "+" that is connected to a
capacitor mounted there at the back of the unit. I assume
this is for electrical noise surpression.
So, am I on the right track? Any other words of wisdom regarding
adapting these high amperage, internally-regulated alternators
to early cars? I am planning to re-wire the whole car, replace the
pointy-ended fuses with modern ones, install headlight relays,
etc.
