generator to alternator conversion

[tttuba]

I am sure at sometime here you have touched on this but can someone give me info on how to wire in an alternator to a generator wire harness? I am replacing the harness on my 47 gmc and someone had done the conversion to alternator but their wiring skills severely lacked. They had redone some of the wiring but all in the same color and with twice the wires that they needed. Needless to say I don't trust what they did and want to know how to do it the right way. The harness has 2 wires that went to the generator and then went to the voltage regulator. The regulator is no longer. The alternator is a one wire but willing to upgrade it to a multi-wire one. Please let me know the correct way to do this.
