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 aluminum 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.
Electronic Points Boxe PN 8106 can be used with the Pro
Mag 12 generators. The Coil is specifically designed to handle
the voltage and current of the Pro Mag and can handle long endurance and marine events as well as drag racing events.
Another unique feature of the Pro Mag 12 is a 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 aluminum 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
