Voltage Regulator - electronic ignition
I would not run a mechanical regulator with any electronic distributor due to potential voltage spikes from the mechanical regulator.
The newer style alternators do not use dual fields, there is still only one field winding, it's just not grounded internally and requires a newer style regulator wired correctly to make it work. They are better than the old system but it requires a bit of work on your part. As stated above, the dgc333 is a good way to go with the least hassle on your part if all you require is a low amperage output.
