The Electronic Points Box is the brain of the Pro Mag 12. These boxes contains electrical circuits that replace the points and are responsible for controlling the power that the generator produces. The Coil is also mounted in this strong, cast aluminium housing. The Points Box controls the spark duration and the unique full power firing sequence of the Pro Mag 12. The energy from the generator is controlled with Field Effect Transistor (FET) technology which is far superior to mags still using points as a trigger source. FETs are much more accurate, durable and capable of handling much more current. This is why the Pro Mag is capable of delivering full energy sparks throughout the entire rpm range of the engine while conventional magnetos fall short of full power at high racing rpm. Plus, the advanced Points Box keeps each spark glowing for up to 26° of crankshaft rotation. Another unique feature of the Pro Mag built-in Soft Touch Rev Control. The rpm limit is adjusted with plug-in modules and will save your expensive engine in the event of driveline failure or missed shifts. The limit is accurate to within 1% and operates by dropping the spark to individual cylinders then firing that plug on the next cycle to avoid filling the cylinder with fuel. This system provides a smooth, backfire free limit. Plus, you can plug in an MSD Two or Three Step Module Selector to provide multiple rpm limits that can be used during warm-up laps or for consistent holeshots. The cast aluminium housing of the Points Box provides a strong mounting foundation for the electronics and coil. All of the circuits receive a heavy duty coating of Humi-Seal for protection against vibration and moisture. Vibration Mounts are supplied along with matching Deutsch connectors and 6,000, 7,000 and 8,000 rpm modules.
