Overcharging 73 Swinger

Ok. I have a 1973 Dodge Swinger, I keep melting my battery feed wire at CE37 to the alternator. Also over charging and the ammeter responds like a tachometer. New regulator, ballast, clean connections at all points. Disconnected the green wire at the alternator and it continues to charge. Disconnect the blue wire and no charge. I'm leaning to an alternator.... any ideas?
