Converting 6 Volt Distributor To 12 Volts

Your coil does care , most factory manufactured coils need a resistor or they will overheat and quit . For about $15 at most part stores , you can get a standard size coil that does not need a resistor and works on straight 12 volt . NAPA "IC14SB" is one I have a part number for .
This comes up all the time on the Ford N tractor boards when converting to 12 volts .

The points do care. If a full 12 volts is used they will burn and pit, and if they're cheap, possibly even have components of the points melt. I learned those the hard way in the early days. You need to have about 2.5-3 ohms of primary resistance to reduce the voltage for points on a 12v system. This can be via the coil alone or it can be the combination of a coil and a resistor.

What year is the the 6 volt distributor (the points and condenser)? Anything '56 and up should be 12 volts already. You should be using a '57 and up distributor if you are using a "modern" carb. You definitely don't want the "Load-o-matic" distributor.
The only time the system should see 12v is during start up.

there's primary and secondary ignition circuits.
the primary is:
12volts>ballast resistor>coil positive terminal>negative terminal>points
> ground (-)
the points open and close the circuit through the ground.
the secondary is:
coil output>coil lead>rotor>distributor cap >plug wire>plugs.

Actually AMERICAN BOY, you have that backwards, the SECONDARY circuit is the secondary wiring of the ignition coil, rotor, distributor cap...

the points and the condenser.
before i can even use these in 12 volt system
i need to figure this out.
this is what Chrysler uses for ballast resistor.
Ballast Resisters
i know these backwards and forwards.
how does ford do it?
reminder: i just have drivetrain. i don't have the rest
of the car/truck.
plus i took break from mechanics for 20 years.

If i was doing it for a non stock application, I'd use one like the mopar unit. I find them more convenient. But for not a whole lot more you can get a 12v coil with enough primary resistance to work fine with points without the ballast resistor. You won't get the 12v bypass when starting but I've never found that to be a problem when everything is in reasonably good condition, and I think most people on here are capable of keeping things in reasonably good condition. That's how I did it when I ran points and I never regretted it.

that built in drop voltage coil is
also the fix for kohler gas engines and
here it comes chevy.
boy we're hitting all the other makes.
where do you put the ford resistor wire?
i'm just talking about physical location,
i don't mean wiring diagram wise.
doesn't sound like something you'd put
in bundle with other wires and put split loom on it.
doesn't it get hot?

The points don't care .
Cheap points dont last long on any voltage .
The capacitors job is to store energy to keep the points , 6v or 12v from burning . The difference between a 6v and 12v capacitor is close enough that it is not worth mentioning unless a feller wants to get technical and split hairs .
