I suspect that the field resistor in the regulator is open circuit, thus when the points break the back e.m.f from the field is discharged across the contacts?

This is mostly for fun, so you can see the control box in operation. Click on picture for video. It will be good if you can get the audio along with it.

There is a wiring error that I did not immediately spot, because it was hooked up with non-original wire colors. The guy had the A and D leads reversed. That caused the extreme arcing. Oddly enough, once correctly wired it worked okay, no damage done.
