Yes
On a 12V system there is "bypass" wiring necessary. So the 12V coil has two inputs to indirectly power the points.. A full 12V input when starting because the starter draws so much and will rob the points of voltage/current. Then after start. the points run on a reduced/resisted voltage off the ballast input so they don't burn out.
So during start you "bypass" the ballast. Ballast drops voltage to approx 9V.
This is all accomplished by a side terminal on a foot starter switch OR an "R" terminal on a solenoid starter OR by an ignition switch with Ign 1, Ign 2 terminals.
A few years used a Looooooong folded "resistance wire" instead of a ballast resistor.
