MSD Blaster 2 coil, with Pertronix ignitor. Instructions say I need a ballast resistor. Do I really need one?
thanks,

The resistor is so you dont blow up the coil when the power is on. Doesnt matter points or electronic. Yes points need a little more resistance so there resistor has more ohms. Basically unless you run a MSD setup you need a resistor thats why they say that specifically. MSD setups dont have the coil wired directly from the igintion switch it runs through there ignition box first. There are very few coils that dont require a resistor and most that dont have one built in already. Pertronix setups still need a resistor unless you run there coil (which probably has one built in already) Its just you have to wire the pertronix box to have a full 12 volts so you cant run it off the resistor wire feeding the other brand of coil.
Basically you need to have a ballast resistor on your setup thats why MSD has it in there instructions.

Ack! I have researched and everything says either yes or no. I guess I'll call pertronix tomorrow.
I bought a ballast resistor with when I got the coil, but then I did something stupid. I started reading and researching, when doesn't seem to clear things up very often.
I'll call soon.
