1. Wire from ignition "ON" terminal to ballast, other side of ballast to coil pos.
2. Wire from starter solenoid "R" terminal to coil pos.
3. Wire from starter battery stud to ammeter. Other side of ammeter to ignition switch battery terminal. (provided ammeter can handle 12V system)
4. White wire (terminal 1 on 10si alternator) goes to a gen light, out gen light to Ignition "ON". or from term 1 straight to ignition "ON". Some folks use a diode inline from term 1 to ignition ON. A diode allows current to travel in one direction only. I use a light bulb, and no diode. The bulb supplies the necessary resistance for the exciter/white wire. It supplies a quick warning of low charge condition.
5. Wire from ignition switch battery terminal or from ammeter hot terminal to push button, out the push button to starter solenoid "S" terminal.
6. Yes, coil neg to dizzy.
7. Start motor.
Using an ammeter is not recommended by me, and I do not offer instructions for it. No. 3 is what the 1951 6V diagram shows.
The junction strip, if that is what it is, is not needed. Take it off.
If you have Pertronix, you didn't say. Do I see a Flame Thrower coil?
