They say due to the type of coil I have (pertronix flamethrower) I do not need a ballast resistor in front of the coil. They say the coil itself has is a 12 volt and has a built in resistor to manage the ingition module.
Does that sound right??? I would prefer not to fry my ignition but if I don't need a resistor I would prefer not to buy one and mount it on the firewall.
I attached the email trail with their specific comments. (it reads from the bottom up)
Thoughts???

Pertronix
Rich, just to let you know ballast resistors do not come in 12-volt / 6-volt
"models". They are rated by the amount of resistance they produce. Example;
you can purchase a 1-ohm, 1.5-ohm, 2-ohm etc resistor. To answer your
questions, no resistor required. The resister is in the coil itself.

so I should still put a 6 volt ballast resistor in front of the coil right?
Any recomendations on type?

Pertronix
Rich, a vast majority of the time there are no issues doing this. The coil
you are using is actually the coil we would recommend for 12-volt systems.

It is a 1167N6 electronic ignition
The coil is a 1.5 ohm part number 40011

Pertronix
Rich, I will need to know the part numbers of both the Ignitor kit and
the coil to advise you.

I have a 53 truck with a 6 volt generator and a 6v negative ground pertronix
ignition with a flamethrower coil. I am contemplating installing a 12 volt
alternator. Can I keep the current pertronix set up if I put a ballast
resistor in front of my current 6v pertronix flamethrower and ignition
module to keep the feed power to the coil at 6 volts.
