Squareback vs round back alternator?

Looks like you are on your way.

Just a point.

One side of the ballast resister should go to the coil. The other side should go to ign 1 and the ign1 side should have battery voltage ( 12 to 15v) with the key in the run position

The coil side should have much less like 5 to 8v depending on the rpm.

The ign2 wire should have approximately 8 to 12 v ONLY while cranking (key in the start position).

The ign2 wire should be attached to the same side of the ballast resister that the coil is attached to.

I assume you seperated the ign1 and ign 2 wire behind the key switch.
