MSD Ignition Installed

The MSD 6a or 6al and Master Blaster or MB II coil does not require or want the ballast resistor.

The ballast resistor is only there to reduce primary voltage to the coil after the engine is running. The full voltage of the system is applied during start.

The MSD does not require this. It wants a full 13.x voltage.

Drop the ballast resistor.

hth,

Jim (anyone want to buy some new ballast resistors?)
