Small ignition question.

Hey guys well good news I have a full ignition system now. With the new cap and rotor kit my 9mm wires work with my dist and looks great. Anyways I finally bought the final bit, the coil. I bought an MSD blaster 2 coil, it came with a ballast resistor, do I need to install this? I will be running the factory points ignition till later when I upgrade it. I really don't want to wire up this thing it won't look as neat, so if it can be avoided I would like to. What does that ballast resistor do anyways I am clueless?

Definately use it! It lowers voltage to the coil. They cost money and MSD would not include it if it was optional.

Are you using the factory ignition wire to the coil? If so, you may not need the ballast as the factory wire is a resistor wire.

Take a voltage reading and call MSD to see if it is in range for use without the ballast resistor.

My factory wire fir the same car as yours is only about 6.5 volts.

I would drop the points and go with an electronic ignition but upgrade you can do.

Yeah I plan to eventually drop the points down the road but not for now.

Max power that is what I was thinking, it is a resistor wire so I will take a reading and give msd a buzz.
