Doug,
Great picture. Your alternator appears to have been converted to a single wire unit. You can see the little black plastic cap that covers the tabs on the internal regulator. You need no other regulator for this setup.
If you connect a Ohmmeter across + and - on your coil, a reading of 3 to 4 ohms means it has a internal resistor and no ballast resistor is needed. A reading on your meter of 1 to 2 means you need to stick a ballast resistor ahead of it.
