I've converted my '68 points distributor to a Pertronix Ignitor. It works fine with the stock coil, and my car does not have a ballast resistor. I got an MSD Blaster2 coil to replace the stock one now (regular 12v coil), and it came with a ballast resistor to use with points ignitions. Since it's a pertronix setup, do I still need to use the ballast resistor? And what is the reason for a ballast resistor?
Anyone using MSD Blaster2 coil with Pertronix ignition?

Yes, you will need to use the ballast resister. The ballest resister lowers the voltage going to the coil so that it doesnt fry. Some coils are designed to not need a ballast resister...and others do, if it came with a resister then you need to use it.
You will want to wire the power for the ignitor to the ignition switch side of the ballast resister (it needs the full voltage).

I'm pretty sure the lower voltage was to protect the points, not the coil. Before I bent my pushrods and had to pull the engine, I was running the Pertronix Ignitor II in the stock dizzy and the matching Flamethrower coil. Worked great. I ran a full 12V to the coil and Pertronix ignition.
that is right that is how they show to wire it. i just installed one in a 55 ford truck with a y-block. no need for the resister.
