That distributor may also be from a "MagSpark" setup. "MagSpark"'s are hard to find and obtuse, so I don't know much about them. I have a "MagSpark" transformer, and it also has three primary terminals, one marked "Ignition" and the other two are obviously for the two leads to the distributor. I'm starting too believe that a "MagSpark" is nothing but and oddly packaged coil with two primary's and one secondary, just like the "FlashFire". Mallory called it a "Transformer", but I see no sign of AC current anywhere.
