If it is a "fast-on" or similar quick connect plug type, they can loose their "grip" and the resistance can build causing the alternator output voltage to drop which the regulator senses and corrects by adding more voltage (or is it current?) to the field. The poor connection can arc or vibration can drop the resistance for a moment and the alternator will pump out an overvoltage. I had this problem and it took me 2 months to finally identify it (with help from Bill Bainbridge at B&C). Are you using a B&B Alternator? If so, you need all three connectors in the male plug housing to stabilize it. You can interconnect 2 of them to utilize both field connection tabs in the alternator for redundancy.
