Thread: ballast or no ballast?

    Default ballast or no ballast?

    Engine: 622 ci chevy bowtie talldeck, marine application, normally aspirated

    ignition: MSD pro billet marine ready to run dist. pn 83606/ and soft touch rev control pn 8728

    Question: Do I have to run a ballast resistor even though the coil I chose says to use an external resistor? It wont start with a resistor and seems to run fine without one. My concern is burning up the coil or my distributor. Thanks

    sandcraft,

    No you do not want any resistor or resistors wires in place. You want to run full 12 volts to the coil and red of the 83606. Make sure that you have a good ground to that set up as well. Same thing applies to the 8728 unit.

    Thanks,
