The 10103 Giulietta Spider diagram I have shows eight wires connected as follows to five terminals on the regulator;
Terminal A1 - three wires; black to horn relay, 16ga red to headlight flashing relay and a 10ga red to the hot side of fuse #3.
Terminal A - one 10ga red wire from the battery cable post on the starter.
Terminal F - one 16ga black wire to the F (I think) terminal on the generator.
Terminal D - two blue wires, one 10ga to the generator and the other to the dynamo light on the dash.
Terminal E - ground
I suspect though that you may have a 750 Series car and I don't know if the wiring is the same. I'll try to find out....
Sorry, but I don't have an 85 diagram; only 84 and 86-88.
If either of you would like these diagrams, please send me your email address in a private message and I'll get them to you.
