I have the stock 73 ignition, points distributor. I am installing an MSD BLaster 2 coil. Do I need to install a ballist resistor, or is the resistor wire from the starter enough?

Thanks, Steve.

If you are using a Points type dist,then it would be recomended to use the ballast.That what i`ve been told anyway :thumbs: :cheers:

the stock ign. has a feed that already has a resistor in it, only full 12V is given on startup, after that it's less.

I would use the ballast resistor and check what voltage you get, there are specs in the MSD manual (aren't there?) Maybe you'll even need 2 resistors, they come in several ratings.

I get 6 volts at the coil with the ballist resistor
